COMMONWEALTH vs. RAYMIE TYREE.

MARSHALL, C.J. We granted the defendant's application for further appellate review to consider his claim that evidence obtained during a warrantless search of a condominium unit (unit) where he was residing should have been suppressed. The defendant also sought to suppress evidence taken from him (his shoes) at the police station after his warrantless arrest, as well as evidence obtained during two subsequent searches of the unit. A Superior Court judge denied the motion to suppress in its entirety, concluding that exigent circumstances had justified the initial warrantless entry and search and that a third search of the unit was undertaken with the consent of the owner. The motion judge made no specific rulings regarding a second search, but his denial of the motion rested on an implicit conclusion that the second search, which was conducted pursuant to a warrant, was permissible. [Note 1] The defendant was convicted on one indictment charging armed robbery while masked, G. L. c. 265, § 17, [Note 2] and one indictment charging possession of a Class B substance, G. L. c. 94C, § 34. In an unpublished memorandum and order pursuant to its rule 1:28, the Appeals Court affirmed. Commonwealth v. Tyree, 72 Mass. App. Ct. 1111 (2008).

For the reasons that follow, we conclude that, at the hearing on the defendant's motion to suppress, the Commonwealth failed to introduce evidence sufficient to satisfy its burden of showing that exigent circumstances justified the initial entry and search of the unit. Evidence obtained during that search, including the defendant's shoes seized at the police station after his arrest, should have been suppressed. We further conclude that evidence as to the armed robbery while masked conviction obtained during the second search was properly seized pursuant to a search warrant

Page 678

and supporting affidavit, and that, as to the drug conviction, evidence of drug paraphernalia was properly admitted under the plain view doctrine. Finally, we conclude that the third search was proper because consent was given by the owner of the unit. Because we cannot conclude that the failure to suppress the evidence obtained pursuant to the initial warrantless entry and search was harmless beyond a reasonable doubt, we reverse the defendant's convictions and remand for a new trial.

1. Facts. We summarize the relevant facts from the motion judge's findings, which are supported by the record, supplemented as necessary with uncontested facts from the motion hearing. [Note 3] At about 9:15 P.M. on April 8, 2003, the manager of the Sun City Variety Store in Tyngsborough was robbed by two masked men. After responding to the scene of the robbery, the police obtained a description of the two armed assailants from the store manager. He informed the police that the assailants had taken money from him and from the store, and had fled in a white "box" van.

Tyngsborough Detective Sergeant Charles C. Chronopoulos was informed by another officer at the scene, Daniel Smith, that Raymie Tyree and Wayne Hoffman fit the store manager's description of the assailants. [Note 4] Officer Smith believed that the two lived at 103 Cardinal Lane. Based on this information, Officer Shaun Wagner was dispatched to 103 Cardinal Lane, a unit adjoining others within a townhouse condominium complex approximately two to three miles from the scene of the robbery. Officer Wagner noticed a white box van in the condominium complex's common parking lot, noted that the hood of the van was still warm to the touch despite the snowy weather, and relayed this information to

Page 679

Sergeant Chronopoulos. Sergeant Chronopoulos and other officers then drove to the condominium complex to join Officer Wagner. [Note 5]

At some point, Sergeant Chronopoulos left the complex, returned to the scene of the robbery, and brought the store manager with him to the condominium complex. The manager told the police that the white box van in the parking lot "looked like" the one the robbers had used. [Note 6] Looking through the van's window, the manager said that a money band that was visible on the front passenger seat looked "similar" to the bands that had been on money taken by the assailants from the store. There is nothing in the record to suggest that anyone inspecting the van would have been visible from 103 Cardinal Lane. [Note 7]

Sergeant Chronopoulos drove the manager back to the store and then returned to the condominium complex, joining five other officers. [Note 8] Two, including Sergeant Chronopoulos, were in plain clothes. The six officers then approached 103 Cardinal Lane. Three officers went to the area behind the unit, while Sergeant Chronopoulos and two others went to the front door. All had their guns drawn. There is no evidence that any lights, movements, or activity of any kind had been seen or heard by the police inside 103 Cardinal Lane at any time.

Shortly after 11 P.M., approximately one hour and forty-five minutes after the robbery, Sergeant Chronopoulos knocked on the front door. After two to three minutes, Sandra Markee, the

Page 680

owner of the unit, opened the door. [Note 9] Sergeant Chronopoulos identified himself as a Tyngsborough police officer and told Markee that the police were investigating an armed robbery. At the motion hearing, Sergeant Chronopoulos and Markee disputed the details of the ensuing conversation. The motion judge found that the officers told Markee they were looking for Tyree and Hoffman in connection with an armed robbery, that the officers "then entered Markee's condominium," and that Sergeant Chronopoulos "then directed Markee to open the sliding glass door in the living room area" so that three officers, who had gone around to the back of the unit, could enter.

Once all six officers were inside, Sergeant Chronopoulos and two other officers went to the basement, with their guns drawn. There they saw and smelled evidence of recent cocaine use. After hearing noises behind a bulkhead door the officers forced the door open and found the defendant, who was "wasted," "disoriented," and "drooling," and "appeared to be under the influence of drugs." Sergeant Chronopoulos also noticed that the shoes the defendant was wearing had soles similar to footprints Sergeant Chronopoulos had seen in the snow outside the Sun City Variety Store shortly after the robbery. The officers arrested the defendant for unlawful possession of narcotics and seized a "crack pipe" and what appeared to be narcotics.

After taking the defendant into custody and conducting a "sweep" of the unit for other individuals, Sergeant Chronopoulos left two officers inside the unit while he went to the Tyngsborough police station to secure search warrants for 103 Cardinal Lane and the white box van. At least one officer remained inside with Markee overnight until Sergeant Chronopoulos returned with other officers at 8:15 A.M. the following day, April 9, 2003, to execute the warrants. [Note 10] During this, the second search, the officers recovered drug paraphernalia, [Note 11] a black winter jacket, and

Page 681

a black semiautomatic replica gun. [Note 12] They also recovered a brown paper money band marked "500" from the right front passenger seat of the van.

Later that day, the police learned that the construction company for which Hoffman worked had reported a white box van as stolen. Hoffman went to the Tyngsborough police station that evening and denied stealing the van. The police did not arrest or charge Hoffman with a crime; they telephoned Markee and asked her to allow Hoffman to stay at 103 Cardinal Lane that night, "presumably in order to keep track of his whereabouts," as the motion judge found. The defendant remained in custody.

Two days later, on April 11, 2003, at about 1 P.M. Sergeant Chronopoulos obtained an arrest warrant for Hoffman. After being brought to the Tyngsborough police station, Hoffman told Sergeant Chronopoulos that guns and masks used in the robbery were in the ductwork in the basement's rafters at 103 Cardinal Lane, but "they would not be there for much longer." [Note 13] Sergeant Chronopoulos and three other officers immediately went to 103 Cardinal Lane, taking Hoffman with them. When Markee opened the door, Sergeant Chronopoulos told her he believed there were weapons in the basement and he wanted to search for them. He presented her with a consent to search form, which she signed. Now searching the unit for the third time, the police recovered a closed duffel bag from the ceiling area of the basement, opened the bag, and found two masks and two replica handguns, one black and one silver.

2. Procedural background. We describe briefly the relevant proceedings in the Superior Court. The defendant moved to suppress the evidence obtained during each of the three searches, including his shoes. [Note 14] At the evidentiary hearing on his motion and in their initial written submissions, the parties' discussion of the initial warrantless entry and search on April 8 focused

Page 682

exclusively on whether Markee had consented to the search. [Note 15] After the hearing the motion judge issued an order, sua sponte, stating: "Although not raised by the parties at the motion hearing or in their Memoranda, the Court would ask both parties to brief the question of whether the entry and search by police of 103 Cardinal Lane on April 8, 2003, was justifiable on the basis of exigent circumstances and/or hot pursuit." [Note 16] After supplemental briefing, the motion judge issued findings of fact and rulings of law, concluding that Markee had not consented to the initial entry and search on April 8, but that, because of exigent circumstances, the officers' initial entry and search was justified. The motion judge further found that Markee had freely and voluntarily consented to the third search of her unit on April 11. [Note 17] The motion to suppress was denied in its entirety. The defendant proceeded at trial with a defense that he was not the person who had committed the robbery with Hoffman.

3. Motion to suppress the evidence seized during the initial warrantless entry and search. In reviewing a ruling on a motion to suppress, we accept the judge's subsidiary findings of fact absent clear error. We independently review the judge's ultimate findings and conclusions of law. Commonwealth v. Colon, 449 Mass. 207, 214, cert. denied, 522 U.S. 1079 (2007).

The Commonwealth does not challenge the motion judge's conclusion that Markee did not voluntarily consent to the initial warrantless entry and search of 103 Cardinal Lane on April 8.

Page 683

We therefore consider first whether that entry and search was justified by exigent circumstances. See Commonwealth v. DeJesus, 439 Mass. 616, 619 (2003). On a careful review of the record we conclude that the Commonwealth did not introduce evidence sufficient to sustain its burden of showing that a search warrant was not required because of exigent circumstances. [Note 18]

The legal principles that govern the resolution of this case are well established. Warrantless searches of a residence presumptively violate the Fourth Amendment to the United States Constitution and art. 14 of the Declaration of Rights of the Massachusetts Constitution. See Commonwealth v. Vuthy Seng, 436 Mass. 537, 549-550, cert. denied, 537 U.S. 942 (2002). The presumption against warrantless searches reflects the importance of the warrant requirement to our democratic society. A warrant ensures that any governmental intrusion into a dwelling "is justified by a careful prior determination of probable cause and necessity" by a neutral arbiter, a judge or magistrate, not by police officers who will themselves carry out the search. K.B. Smith, Criminal Practice and Procedure § 4.18 (3d ed. 2007). See Commonwealth v. Marquez, 434 Mass. 370, 374 (2001), quoting Commonwealth v. Forde, 367 Mass. 798, 805 (1975) ("The right of police officers to enter into a home, for whatever purpose, represents a serious governmental intrusion into one's privacy. It was just this sort of intrusion that the Fourth Amendment

Page 684

[and art. 14 were] designed to circumscribe by the general requirement of a judicial determination of probable cause" [emphasis added]).

Given the high value that our Federal and Massachusetts Constitutions assign to the warrant requirement, particularly in relation to a dwelling, we impose a heavy burden on the Commonwealth to justify every warrantless search: in the absence of consent, the Commonwealth must prove both probable cause to enter the dwelling [Note 19] and the existence of exigent circumstances. See Commonwealth v. DeJesus, supra (for nonconsensual entry to be valid, there "must be probable cause and there must be exigent circumstances"). Under the exception for exigent circumstances, "there must be a showing that it was impracticable for the police to obtain a warrant, and the standards as to exigency are strict." Commonwealth v. Forde, supra at 800, and cases cited. See Commonwealth v. Washington, 449 Mass. 476, 486 (2007), quoting Commonwealth v. Cast, 407 Mass. 891, 904 (1990) (Commonwealth "must show . . . 'that it was impracticable for [officers] to get a warrant' " [emphasis in original]).

Notwithstanding these foundational requirements, the Commonwealth asks us to hold that exigent circumstances always justify a warrantless entry and search in the aftermath of a crime involving a firearm where the police have reason to believe (i.e., probable cause) that an armed suspect is in a particular place, even in circumstances where it is not impracticable to obtain a warrant. None of the cases on which the Commonwealth relies, nor any decided since Commonwealth v. Forde, supra, supports so broad a proposition. [Note 20], [Note 21]

The Commonwealth is correct that some of the circumstances

Page 685

to which courts have looked to determine whether exigent circumstances exist were present in this case. See Commonwealth v. Forde, supra at 801, 807 (stating that whether exigent circumstances exist depends on consideration of "the circumstances in their totality" and suggesting circumstances that "have tended to support a finding of exigency"). There was "a showing that the crime was one of violence or that the suspect was armed." Id at 807. There was a "clear demonstration of probable cause." Id. And there was "strong reason to believe that the suspect was in the dwelling." Id. However, evidence of additional circumstances, one or more of which invariably is present in our cases supporting a conclusion of exigency, was wholly absent in this record. We focus on four such circumstances relied on by the motion judge for which there was no record evidence.

(a) Risk of destruction of evidence. The Commonwealth argues, and the motion judge summarily agreed, that there was a risk that evidence at 103 Cardinal Lane, specifically money and physical evidence such as clothing and guns, would be lost or destroyed absent immediate police action. The record does not suggest any such threat, for at least two reasons. See Commonwealth v. DeJesus, 439 Mass. 616, 621 (2003) (warrantless entry impermissible "in the absence of specific information supporting an objectively reasonable belief that evidence will indeed be removed or destroyed unless preventative measures are taken"); Commonwealth v. Huffman, 385 Mass. 122, 126 (1982) (same).

First, the circumstances in this case were insufficient to support an objectively reasonable belief that the stolen money imminently would change hands. The Commonwealth argues that

Page 686

stolen "cash is likely to be disposed of quickly," and we have noted "the fungible nature of money in general, and the tendency of illicit money to change hands quickly." Commonwealth v. Washington, 449 Mass. 476, 485 (2007). But in each case in which money was the focus of the warrantless search, the conduct underlying the search involved ongoing illegal drug activities where further drug sales or purchases were possible. See id. at 478 (exigent circumstances where suspects were driving away from drug deal and could have disposed of cash had police not acted immediately); Commonwealth v. Lopez, 38 Mass. App. Ct. 748, 750 (1995) (exigent circumstances where surveillance outside apartment building after controlled drug buy could not prevent money from being transferred between apartments inside); Commonwealth v. Lee, 32 Mass. App. Ct. 85, 87-89 (1992) (exigent circumstances where drug sale occurred in defendant's supermarket and surveillance without entry could not prevent money from changing hands quickly inside and evading detection). Here, the record reveals that the police had no reason to suspect that any illicit drug distribution was occurring at the unit, [Note 22] and the suspects had no way to slip the stolen cash out of the unit while the police maintained their surveillance at the front and rear of the premises. See Commonwealth v. Washington, supra at 478; Commonwealth v. Lopez, supra; Commonwealth v. Lee, supra.

Second, the Commonwealth maintains, and the judge found, that any delay risked the destruction of the suspects' clothing and masks. However, the record reveals no reasonably objective basis to believe that the guns and clothing used in the robbery were "susceptible to destruction or removal" from the unit. Commonwealth v. Cataldo, 69 Mass. App. Ct. 465, 474 (2007). The police had a presence at the front and the rear of the unit prior to the warrantless entry, no evidence suggests that the occupants were aware of the police presence during that time, and no evidence suggests that they had any incentive to remove or destroy evidence, or that they might be in the process of doing

Page 687

so. See Commonwealth v. DeJesus, supra at 620 n.3; Commonwealth v. Molina, 439 Mass. 206, 210 (2003); Commonwealth v. Huffman, supra at 125-127. See also Part 3 (b), infra.

(b) Risk of a suspect's flight. Risk of a suspect's escape is another circumstance that may support a finding of the requisite "exigency" for a warrantless search. See Commonwealth v. Forde, 367 Mass. 798, 807 (1975) ("a likelihood that the suspect would escape if not apprehended" is one relevant circumstance in evaluation of exigency). The Commonwealth does not argue that any information available to the police before they entered 103 Cardinal Lane supports the motion judge's statement that any delay to obtain a warrant "would have also risked the possibility of the assailants fleeing," and correctly so, for there is no such evidence. [Note 23] To the contrary, the assailants were masked and had no reason to believe the store manager might recognize them. (He did not.) Cf. Commonwealth v. Duarte, 56 Mass. App. Ct. 714, 720 (2002) (that victim and assailant knew one another increased likelihood that assailant "would flee to avoid apprehension or, at a minimum, take prompt action to conceal" or otherwise dispose of evidence). Nor did they have reason to believe police were likely to locate them in the immediate aftermath of the robbery: there was no evidence that the assailants were followed as they left the store, and the police were led to 103 Cardinal Lane only by information an officer had obtained during the investigation of a wholly unrelated domestic incident. [Note 24], [Note 25] The police had made no contact with any individual

Page 688

who was likely to have warned the suspects that the police were searching for them. See Commonwealth v. Lee, supra at 90 (exigent circumstances where suspect's son and others had just been arrested and would likely be able to contact suspect soon).

In addition, the presence of officers at both the front and rear of the unit made escape unlikely, and there was no evidence suggesting that anyone inside 103 Cardinal Lane was aware of, or likely to be aware of, the police presence outside the unit before Sergeant Chronopoulos knocked on the front door. See Commonwealth v. Huffman, supra at 125 n.6 ("Exigent circumstances may arise if a defendant becomes aware, or is certain to become aware, of an officer's presence"). [Note 26] When Sergeant Chronopoulos knocked on the front door, Markee opened the door and gave the police no reason to believe that the possible suspects had been apprised of the police presence, nor did the police see or hear signs of other occupants. See Commonwealth v. Colon, 449 Mass. 207, 217, cert. denied, 522 U.S. 1079 (2007) (exigent circumstances where there was no response after police knocked, but officers heard noises inside); Commonwealth v. Moran, 370 Mass. 10, 12 (1976) (same). [Note 27]

Page 689

In short, on the record before us, the police had no reason to believe that the suspects were likely to flee the residence in the time it would have taken to procure a warrant to search the premises.

(c) Risk of harm to police or others. In Commonwealth v. Moran, supra, this court held that exigent circumstances existed where the police had reason to believe that seeking a warrant would jeopardize the safety of police or others. See Commonwealth v. Moore, 54 Mass. App. Ct. 334, 340 (2002); Commonwealth v. Saunders, 50 Mass. App. Ct. 865, 875 (2001), S.C., 435 Mass. 691 (2002); Commonwealth v. Donoghue, 23 Mass. App. Ct. 103, 108-109 (1986), cert. denied, 481 U.S. 1022 (1987). Although the motion judge stated that any delay in entering 103 Cardinal Lane to obtain a warrant "risked . . . harming the officers and anyone else inside 103 Cardinal Lane," the record is devoid of any evidence to support that conclusion, and the judge cited none. [Note 28], [Note 29]

The Commonwealth argues that "[i]nherent" in the aftermath of any violent crime or crime involving a firearm is "an objectively reasonable belief" that there is a "likelihood" that others will be harmed if police maintain physical surveillance of the premises while seeking a warrant. Were we to agree, no warrant would be required in any case where the police search for suspects in the aftermath of a violent crime. None of our cases supports

Page 690

such a ruling. Here, no evidence suggests that the police were in any danger prior to their entry or that they believed Markee, whom they knew to be the occupant of the unit, was in danger. The entry occurred in the middle of the night, and there is no evidence that any other persons were in the vicinity, or likely would be. See Commonwealth v. Moore, supra at 338 (exigent circumstances where officers immediately responded to reports of shots being fired from apartment window); Commonwealth v. Saunders, supra (exigent circumstances where armed suspect fled from police into densely populated apartment complex at time when children were about to begin leaving for school). The police had no reason to believe that immediate action was necessary to locate any victims. See Commonwealth v. McDermott, 448 Mass. 750, 766-767, cert. denied, 552 U.S. 910 (2007) (exigent circumstances where officers feared more victims may be in suspect's residence after suspect killed seven coworkers in shooting rampage); Commonwealth v. Young, 382 Mass. 448, 457-458 (1981) (exigent circumstances where trail of blood from murdered body led police directly to apartment); Commonwealth v. Donoghue, supra at 108 (exigent circumstances where "unusually brutal" nature of assault that had just occurred suggested suspect was dangerous and there may be other victims). Nor was there any evidence to suggest that the suspects were likely to engage in violence to avoid capture while the police sought a warrant.

(d) Impracticability of obtaining a warrant. In evaluating whether exigent circumstances existed, we also have placed particular emphasis on whether police "consider[ed] how long it would take to obtain a warrant" before acting, Commonwealth v. Pietrass, 392 Mass. 892, 899 (1984), and whether police engaged in an unjustified delay before seeking a warrant. Here the record is devoid of evidence that obtaining a warrant before the police entered the unit was impracticable. See Commonwealth v. Huffman, 385 Mass. 122, 125 (1982) (no exigent circumstances where "Commonwealth did not offer any evidence as to the time it would take to get a warrant, or indicate that it would be impractical to get one"). [Note 30] Cf. Warden, Md. Penitentiary v. Hayden, 387 U.S. 294, 298-299 (1967) (exigent circumstances where police converged on suspect's house within minutes of armed

Page 691

robbery and speed "was essential" to protect officers and prevent escape). There is no evidence that the police had reason to believe that a warrant would be unobtainable had they sought one before entering the unit. Contrast Commonwealth v. Boswell, 374 Mass. 263, 270-271 (1978) (exigent circumstances where probable cause was "in doubt" before police knocked on door and recognized person who answered as suspect).

(e) Conclusion. For purposes of reviewing whether a warrantless search falls within the narrow exception of exigent circumstances, we evaluate "the scene as it could appear to the officers at the time, not as it may seem to a scholar after the event with the benefit of leisured retrospective analysis." Commonwealth v. DeJesus, 439 Mass. 616, 620 n.3 (2003), quoting Commonwealth v. Young, supra at 456. In this case, neither the police nor the Commonwealth defended the warrantless entry and search on the basis of exigent circumstances until after the motion judge invited them to do so. See notes 15 and 16, supra. We are reticent to apply a "leisured retrospective analysis," Commonwealth v. Young, supra, and to disregard the perceptions of officers at the scene who had not suggested that an exigency existed. See Commonwealth v. DiGeronimo, 38 Mass. App. Ct. 714, 727 (1995) (finding of exigency "cannot rest on an after-the-fact discovery of a justification that never occurred to, nor was mentioned by, the police but is subsequently imputed to them in an effort to salvage a well-intentioned but flawed prosecution"). No facts in evidence support a conclusion of exigent circumstances. [Note 31] Evidence

Page 692

discovered and seized during the initial entry and search on April 8 should have been suppressed. [Note 32]

4. Search pursuant to a warrant on April 9. The warrantless entry into and search of 103 Cardinal Lane on April 8 were invalid. Accordingly, we must now consider whether that initial illegality impermissibly tainted the evidence seized by the police during the second search of the unit on the following day, after the police had secured a search warrant. Here too the law is settled, and in applying it to the facts in this case -- in particular the affidavit of Sergeant Chronopoulos signed in support of the warrant -- we conclude that the evidence seized during the April 9 search was admissible.

Evidence obtained during a search pursuant to a warrant that was issued after an earlier illegal entry and search is admissible as long as the affidavit in support of the application for a search warrant contains information sufficient to establish probable cause to search the premises "apart from" observations made during the initial illegal entry and search. Commonwealth v. DeJesus, 439 Mass. 616, 625 (2003). In such circumstances, the search pursuant to a valid warrant provides an independent source for the challenged evidence "untainted by information discovered during the initial [illegal] entry." Id. at 627. See Commonwealth v. Blake, 413 Mass. 823, 830 (1992), quoting Segura v. United States, 468 U.S. 796, 813-814 (1984) ("Whether the initial entry was illegal or not is irrelevant to the admissibility of the challenged evidence [if there is] an independent source for the warrant under which the evidence was seized").

After excluding all information obtained from the impermissible

Page 693

warrantless entry and search, we conclude that the remaining portions of Sergeant Chronopoulos's affidavit in support of the search warrant contained more than adequate information to support a finding of probable cause to search 103 Cardinal Lane and the white box van for evidence related to the armed robbery. [Note 33] The untainted information in the affidavit included the store manager's description of the two assailants and the white box van; Officer Smith's knowledge that Hoffman and the defendant fit the description of the assailants, were known to be driving a white box van, and were living at 103 Cardinal Lane; the discovery of the white box van parked in the condominium complex's parking lot with its hood warm to the touch; and the store manager's identification of the white box van and the money band visible through the van's window. Because the untainted information in the Chronopoulos affidavit established probable cause to believe evidence related to the armed robbery would be found at 103 Cardinal Lane and inside the van, justifying the issuance of the search warrants, the black jacket found in the unit and the paper money band found in the van as the result of the April 9 search were properly admitted.

The seizure of the drug paraphernalia -- the scale, razors, baking soda, and other drug-related items, see note 11, supra -- during the April 9 search raises a different inquiry. The portions of the search warrant explicitly authorizing their seizure were based on the paragraphs of the Chronopoulos affidavit that described items he had seen in the condominium unit during the illegal search on April 8. Excluding these observations, the Chronopoulos affidavit contains insufficient information to establish probable cause to search 103 Cardinal Lane for evidence of drug use or distribution. Accordingly, those portions of the search warrant permitting officers to search for such evidence were invalid. See United States v. Harris, 403 U.S. 573, 577

Page 694

(1971) ("showing of probable cause" is "necessary to support a search warrant"); Commonwealth v. Lett, 393 Mass. 141, 142 (1984) ("tainted portion of a search warrant is severable from the valid portion").

Our conclusion that the drug-related evidence was seized pursuant to tainted portions of the search warrant, however, does not end the matter. As we now explain, the items of drug paraphernalia were properly admissible under the plain view doctrine, which became operative when the valid search was conducted on April 9.

Items seized pursuant to invalid portions of a warrant need not be suppressed if they were discovered in plain view during a search authorized by the valid portions of the warrant. Commonwealth v. Lett, supra at 147. Under the plain view doctrine, "if police are lawfully in a position from which they view an object, if its incriminating character is immediately apparent, and if the officers have a lawful right of access to the object, they may seize it without a warrant." Commonwealth v. Hinds, 437 Mass. 54, 61 (2002), cert. denied, 537 U.S. 1205 (2003), quoting Commonwealth v. D'Amour, 428 Mass. 725, 730-731 (1999). "In the case of contraband and fruits and instrumentalities of crime, the nexus to criminal activity is obvious." Commonwealth v. Balicki, 436 Mass. 1, 8 (2002), quoting Commonwealth v. D'Amour, supra at 731. It was immediately apparent to the police that the drug paraphernalia discovered during the valid search on April 9 were instrumentalities of crime. [Note 34]

Under art. 14, the plain view doctrine applies only if the police come across the item inadvertently. Commonwealth v. Balicki, supra at 8-9. We have concluded, however, that the inadvertence requirement is "particularly ill-suited when applied to items listed in the invalid portion of a severed warrant, for it [is] at odds with the more . . . basic requirement that search warrants describe things to be seized with particularity."

Page 695

Commonwealth v. Lett, supra, quoting United States v. Freeman, 685 F.2d 942, 954 n.7 (5th Cir. 1982). Where, as here, police seize items listed in the invalid portion of a partially valid warrant, the proper inquiry "is not whether the discovery was inadvertent but whether the items seized in plain view were seized within the scope and intensity of the search permitted under the terms of the valid portions of the warrant." Commonwealth v. Lett, supra. See Commonwealth v. D'Amour, supra at 730.

The search the police conducted on April 9 was appropriate in scope and intensity to the valid portions of the warrant. The items of drug paraphernalia were all discovered on a table in the basement bedroom or in the "cellar storage area," areas where the guns and masks the officers were seeking could have been hidden. The drug paraphernalia seized in plain view during the April 9 search pursuant to the valid portions of the search warrant were properly admitted in evidence at trial.

5. Search pursuant to consent of owner. We turn now to the third and final search, and affirm the motion judge's finding that the search was justified by Markee's consent. Police may search a house without a warrant if a person with "common authority" over the premises consents, freely and voluntarily, to the search. United States v. Matlock, 415 U.S. 164, 171 (1974). In such cases, the Commonwealth "must show 'consent unfettered by coercion, express or implied.' " Commonwealth v. Sanna, 424 Mass. 92, 97 (1997), quoting Commonwealth v. Voisine, 414 Mass. 772, 783 (1993). The Commonwealth must also establish "something more than mere 'acquiescence to a claim of lawful authority.' " Commonwealth v. Sanna, supra, quoting Commonwealth v. Voisine, supra. "The voluntariness of an individual's consent to a warrantless entry is an issue of fact, and must be examined in the circumstances of the case. . . . When reviewing the denial of a motion to suppress evidence, we accept the motion judge's subsidiary findings of fact absent clear error." (Citations omitted.) Commonwealth v. Sanna, supra. Here the motion judge's finding that Markee voluntarily consented to the officers' search of her home on April 11 is fully supported by the record.

Markee signed a consent to search form before the officers

Page 696

entered her home on April 11 to conduct the search. [Note 35] Markee testified that she did not read the form, nor was it read to her by any of the officers, but she signed the form because she "was told" her house would be "wrecked" if she did not do so. There was no evidence that Markee could not read, and the judge clearly discredited her testimony on this point, as he was free to do.

The defendant argues that Markee's consent was not freely given because it was obtained through the "exploitation" of a prior illegality, specifically the warrantless entry and search on April 8, three nights earlier. We disagree. Police may rely on consent to conduct a search despite a previous invalid entry or search, so long as the "consent was an act of free will, unaffected by the taint of the [prior] illegality." Commonwealth v. Loughlin, 385 Mass. 60, 63 (1982), citing Brown v. Illinois, 422 U.S. 590, 603-604 (1975). Three days had passed since the initial invalid entry before Markee gave her consent for the search on April 11, during which time she had agreed, at the request of the police, that Hoffman could stay with her, and the police had searched the unit a second time pursuant to a partially valid search warrant. See Part 4, supra. Based on all the evidence, we conclude that the effects of the illegality of the initial search had sufficiently dissipated and did not taint Markee's later consent. Contrast Commonwealth v. Loughlin, supra at 64 (consent tainted when suspect was not advised of his right to refuse consent, "[n]o significant time elapsed between the illegality and the 'consent,' " and no "intervening event occurred that dissipated the effect of the illegality"). Finally, as the evidence shows, Markee's "words and actions placed no limitations on the scope of the entry to which [s]he was consenting." Commonwealth v. Sanna, supra at 99. The guns and masks discovered in the course of the search on April 11 were properly admitted.

6. Motion to suppress defendant's shoes seized at the police station. Our conclusions regarding the validity of the three searches do not end our analysis. The Commonwealth, citing Commonwealth v. Street, 56 Mass. App. Ct. 301, 307-309 (2002), argues that the defendant's shoes, which were seized at the

Page 697

police station after his arrest, were properly admitted, even if the arrest of the defendant in the condominium on April 8 was invalid because it was made in the course of an illegal entry and search of 103 Cardinal Lane. We disagree.

The question here is whether evidence -- in this case shoes -- taken from the defendant after his arrest in the course of an unlawful entry or search is the "fruit of the poisonous tree" and thus not admissible, or whether such evidence is untainted and thus admissible. See Wong Sun v. United States, 371 U.S. 471, 484-488 (1963); Commonwealth v. Damiano, 444 Mass. 444, 453-454 (2005). In Commonwealth v. Pietrass, 392 Mass. 892, 900 (1984), this court held that, when police make an arrest within a dwelling after an unlawful warrantless entry, they have "no legal justification for being inside" and can "justify" their seizure of clothes worn by the defendant at the time of the arrest "neither on the basis of the 'plain view' doctrine nor as a search incident to a lawful arrest. Similarly, the clothing taken from the defendant" at the police station after the illegal arrest "must be suppressed as 'fruit of the poisonous tree.' " Id., quoting Wong Sun v. United States, supra. [Note 36], [Note 37]

In Commonwealth v. Street, supra, the Appeals Court concluded that the Pietrass case had been implicitly overruled on

Page 698

the issue whether items seized from a defendant outside the home following an illegal warrantless entry or search are admissible by Commonwealth v. Marquez, 434 Mass. 370 (2001) (Marquez). See Commonwealth v. Street, supra at 308 n.12. In Marquez, supra at 372, 377-379, we "adopt[ed] the principles enunciated" in New York v. Harris, 495 U.S. 14 (1990) (Harris), that "where the police have probable cause to arrest a suspect, the exclusionary rule [of the Fourth Amendment] does not bar [the admission] of a statement made by the defendant outside of his home, even though the statement is taken after an arrest made in the home in violation of [his rights]" (emphasis added). Marquez, supra at 372 n.1, quoting Harris, supra at 21. The Appeals Court reasoned that, if the exclusionary rule did not bar the admission of statements made by the defendant outside the home following his arrest in the wake of an illegal home search, then items of clothing seized from the defendant outside the home following his arrest in the wake of an illegal home search must also be admissible. [Note 38] Commonwealth v. Street, supra at 309, citing Harris, supra, and Marquez, supra. We conclude that the reasoning in Marquez and Harris concerning a defendant's

Page 699

statements does not extend to the seizure of the defendant's shoes at the police station after he was arrested on the illegal entry of 103 Cardinal Lane.

As we explained in Marquez, supra at 377, quoting Harris, supra at 20, "the purpose of the warrant requirement for an arrest in the home is 'to protect the home, and anything incriminating the police gather[] from arresting [a defendant] in his home' " (emphasis added). The warrant requirement serves an important deterrent purpose: to ensure "the police know that a warrantless entry will lead to the suppression of any evidence found, or statements taken, inside the home" (emphasis added). Harris, supra at 20. See Marquez, supra at 378. We also noted, however, that an "arrest in a home without a warrant but with probable cause" does not render unlawful "continued custody of the suspect once he is removed from the house." Id. at 377-378, quoting Harris, supra at 18. Thus the statement made by the defendant at the police station "was not the product of being in unlawful custody [and] [n]either was it the fruit of having been arrested in the home rather than someplace else" (emphasis added). Marquez, supra at 378, quoting Harris, supra at 19. Upholding "otherwise valid statements given by defendants at the police station" after an "invalid arrest," we concluded, would not weaken the deterrent purpose of the warrant requirement. Marquez, supra.

That deterrent purpose would, however, be impaired by allowing the police to acquire items in the defendant's possession at the time of an arrest in the course of an illegal warrantless entry or search. There is a significant difference in the speech at issue in the Marquez and Harris cases and the item (shoes) seized by the police from the defendant in this case. As an attribute of the person, speech is indistinguishable from the person himself; it goes where he goes, and is not "property" that can be "owned" and "alienated" in the usual sense of those words. On the other hand, physical items in the arrestee's possession that are seized following an illegal warrantless search are "the fruit of [the defendant's] having been arrested in the home rather than someplace else." Marquez, supra at 378, quoting Harris, supra at 19. The particular clothing, shoes, or other physical items an arrestee is wearing or carrying depend directly

Page 700

on the time and place of the arrest. Permitting the postarrest seizure of those items in the wake of a warrantless entry or search would invite the police to circumvent the well-settled rule that, in the course of an illegal warrantless entry and search, any physical evidence police take "from the defendant" while still in the home must be suppressed. See Marquez, supra. The risk of manipulation is particularly apparent in cases where, as here, the police note the potential evidentiary relevance of a piece of a suspect's clothing while they are still unlawfully in the home. Just as statements made in the course of an illegal entry or search must be suppressed, see id., so, too, must clothing or shoes the defendant was wearing and other items that were in the defendant's possession at the time of entry. We cannot assume the defendant would have been wearing the same shoes had the police proceeded by summons or waited to arrest him lawfully at another time or place. See Commonwealth v. O'Connor, 406 Mass. 112, 117 (1989) (unlawfully discovered evidence admissible when discovery of evidence "by lawful means was certain as a practical matter"). [Note 39] The defendant's shoes should have been be suppressed.

7. Harmless error. Having concluded that the evidence seized during the initial entry and search on April 8 and the defendant's shoes, which were seized immediately thereafter at the police station, should have been suppressed, we must now determine whether the erroneous admission of that evidence was "harmless beyond a reasonable doubt." Chapman v. California, 386 U.S. 18, 24 (1967). See Commonwealth v. Molina, 439 Mass. 206, 211-212 (2003) (constitutional errors preserved before or during trial reviewed to determine whether they are "harmless beyond a reasonable doubt"); Commonwealth v. Perez, 411 Mass. 249, 260 (1991) (same). See also Commonwealth v. Vinnie, 428 Mass. 161, 163-164, cert. denied, 525 U.S. 1007 (1998) (harmless beyond reasonable doubt standard for preserved constitutional errors is more favorable to defendant

Page 701

than standards applicable to certain other errors). We have recognized that a constitutional violation gives rise to presumptive prejudice that can be overcome only where the Commonwealth makes an "affirmative showing" of harmlessness beyond a reasonable doubt. Commonwealth v. Rios, 412 Mass. 208, 214 (1992). Commonwealth v. Macdonald (No. 1), 368 Mass. 395, 399 (1975).

In considering the "essential" question "whether the error had, or might have had, an effect on the jury and whether the error contributed to or might have contributed to the verdicts," Commonwealth v. Perrot, 407 Mass. 539, 549 (1990), our focus is not on whether the jury could have convicted the defendant had the tainted evidence been excluded; it is not enough for the Commonwealth to demonstrate that its other, properly admitted evidence was "sufficient" to convict the defendant or that the inadmissible evidence was "consistent" with the admissible evidence. Commonwealth v. Dagraca, 447 Mass. 546, 554-555 (2006). See Commonwealth v. Marini, 375 Mass. 510, 520-521 (1978) (error not harmless beyond reasonable doubt despite admissible evidence that "would certainly have been enough to warrant a guilty verdict"). Rather, we ask whether, on the totality of the record before us, weighing the properly admitted and the improperly admitted evidence together, we are satisfied beyond a reasonable doubt that the tainted evidence did not have an effect on the jury and did not contribute to the jury's verdicts. We look to factors such as "the importance of the evidence in the prosecution's case; the relationship between the evidence and the premise of the defense; who introduced the issue at trial; the frequency of the reference; whether the erroneously admitted evidence was merely cumulative of properly admitted evidence; the availability or effect of curative instructions; and the weight or quantum of evidence of guilt." Commonwealth v. Dagraca, supra at 553, and cases cited. See also Commonwealth v. Mahdi, 388 Mass. 679, 697 (1983) (these factors, though "useful," are "not exclusive or exhaustive"). We apply the principle of harmless beyond a reasonable doubt "with restraint." Commonwealth v. Gilday, 367 Mass. 474, 498 (1975). An assertion that the error is harmless beyond a reasonable doubt is most particularly vulnerable where the over-all

Page 702

strength of the Commonwealth's case radiates from a core of tainted evidence. See, e.g., Commonwealth v. Dagraca, supra at 554 (error not harmless: "By introducing the defendant's improperly procured admissions twice during trial and then highlighting them during closing argument, the prosecutor unmistakably relied on them in a significant way. This was not surprising, precisely because the defendant's admissions to the police were the only direct evidence that he lived in the house").

Here, the prosecutor's closing argument, summarizing the evidence she argued to the jury was the most damaging to the defendant, reveals that the Commonwealth's case stood on a foundation of improperly admitted evidence. The prosecutor repeatedly tied the defendant to the crimes by referring to tainted evidence, and referred to the tainted evidence in order to corroborate the testimony of the police officers and, more important, the critical testimony of Hoffman, who had been called by the Commonwealth and whose credibility was otherwise significantly undermined on cross-examination. [Note 40] The prosecutor told the jury, among other things, that:

(1) The defendant's shoes seized by the police and the shoe print evidence placed the defendant "at the scene at Sun City Variety that night behind that dumpster exactly where [the store manager] said the man who robbed him was standing," and "also corroborate[] the other things that Wayne Hoffman told you" (emphasis added). [Note 41]

(2) The drugs and the crack pipe the police found in the warrantless search of 103 Cardinal Lane on April 8, as

Page 703

well as the defendant's presence in the bulkhead of the unit's basement, were "consistent with what Wayne Hoffman told you happened that night" (emphasis added).

(3) "[Hoffman] told you that they had committed that robbery because they needed money for drugs. He told you that they had bought the drugs from the dealer when the dealer arrived at the home after they got back. Gave him the money, they bought drugs, they burned the drugs down to a form where it could be smoked and they smoked them using a crack pipe. That's consistent with what the detectives found when they arrived there" (emphasis added).

(4) "You also need to evaluate [Hoffman's] testimony just as you evaluate the testimony of any other witness for credibility. You need to compare it to the other evidence in the case. . . . So compare [Hoffman's testimony] to the other evidence in this case, see what corroborates what he told you" (emphasis added). [Note 42]

(5) "I would suggest to you doesn't [evidence that only a small amount of drugs were found in 103 Cardinal Lane on April 8] corroborate what Wayne Hoffman told you?" (emphasis added).

The repeated emphasis on the improperly admitted evidence in the prosecutor's closing argument -- including, among other things, the officers' observations of the defendant's intoxicated state and presence in the basement of the unit and the drugs seized in the course of the warrantless search on the night of April 8, and the discovery of the defendant wearing shoes with soles that matched prints made at the scene of the robbery -- reflects the centrality of that evidence to the Commonwealth's case, including the vital importance of inadmissible evidence in shoring up Hoffman's credibility. Indeed, beyond Hoffman's testimony and the fact that the defendant was residing with Markee at 103 Cardinal Lane, no untainted evidence ties the

Page 704

defendant to the van, the drugs, [Note 43] the guns and the masks, or the store on the night of the robbery. We cannot ignore that the improperly admitted evidence had the dual purpose of both tying the defendant to the crime and supporting Hoffman's credibility, thus intensifying the harm to the defendant's rights. The "cumulative prejudicial effect[s]" of the evidence that should have been excluded, Commonwealth v. Charros, 443 Mass. 752, 766, cert. denied, 546 U.S. 870 (2005), quoting Fahy v. Connecticut, 375 U.S. 85, 91 (1963), struck "at the jugular of the defendant's . . . defense" that he was not Hoffman's accomplice. Commonwealth v. Mahdi, 388 Mass. 679, 697 (1983). The unlawful evidence "contributed to or might have contributed to the verdicts" (citations omitted). [Note 44] Commonwealth v. Molina, 439 Mass. 206, 212 (2003), quoting Commonwealth v. Perrot, 407 Mass. 539, 549 (1990). A new trial, conducted in accordance with today's holding, is mandated.

8. Conclusion. For the reasons stated above, the defendant's convictions cannot stand. Accordingly, the judgments are reversed, the verdicts are set aside, and the cases are remanded to the Superior Court for a new trial.

So ordered.
