WILLIAM JANSEN, petitioner.

SPINA, J. We consider in this case a challenge to an order entered by a judge in the Superior Court, pursuant to Mass. R. Crim. P. 17 (a) (2), 378 Mass. 885 (1979), [Note 1] that William Jansen

Page 113

submit to a buccal swab for deoxyribonucleic acid (DNA) analysis [Note 2] at the request of Richard C. Lampron, the defendant in pending aggravated rape cases, who contends that the DNA analysis will yield exculpatory evidence that is highly relevant to his defense. Jansen is not a codefendant in the criminal proceedings against Lampron, nor has he been charged separately with any offense. Jansen sought review of the judge's order by filing a petition for relief pursuant to G. L. c. 211, § 3, with a single justice of this court, who reserved and reported the matter, without decision, to the full court. [Note 3] For the reasons that follow, we affirm the order.

During the evening of September 24, 1998, at a house in Lee shared by Lampron, Jansen, and Aaron Kincaid, the victim, Gail, [Note 4] was allegedly drugged and sexually assaulted. [Note 5] Being acquainted with all three men, Gail identified Lampron and Kincaid as the only two perpetrators, although Jansen was also present in the house at the relevant time. Kincaid purportedly showed a videotape of the incident to some friends, but it has since been destroyed. [Note 6]

On March 25, 1999, Lampron was indicted on four charges of aggravated rape (G. L. c. 265, § 22), and on March 31, 1999,

Page 114

he was indicted on one charge of administering a drug with intent to stupefy or overpower to enable sexual intercourse (G. L. c. 272, § 3). He then fled the jurisdiction until March, 2002, when he was returned to Berkshire County. In the meantime, Kincaid was tried and convicted on four indictments charging aggravated rape, arising from the events of September 24, 1998. See Commonwealth v. Kincaid, 61 Mass. App. Ct. 657, 657, S.C., 444 Mass. 381 (2005).

Among the items produced at Kincaid's trial was a hair "barrette" [Note 7] that Gail claimed was inserted in her vagina during the sexual assaults. DNA testing conducted at the behest of the State police crime laboratory during its investigation indicated that there was a mixed sample of DNA in sperm fraction on the barrette. Kincaid was the primary source of the DNA, a fact that he apparently did not challenge because his defense was that he had engaged in consensual sexual intercourse with Gail on the night in question. The other source of DNA on the barrette was not identified at his trial.

Once Lampron was returned to Berkshire County, the Commonwealth filed a motion to obtain a blood sample, which was allowed. DNA testing on that sample could not definitively include or exclude Lampron as a minor source of DNA found on the barrette. On May 14, 2002, Lampron filed a motion for an order to take a blood sample from Jansen, claiming that such sample would lead to material and relevant evidence that was crucial to establishing Lampron's innocence. A judge denied his motion, concluding that Lampron had failed to demonstrate the requisite probable cause for the issuance of such an order.

Lampron then hired a private investigator to obtain a sample of Jansen's DNA. During the early morning of July 23, 2004, the investigator's associate saw a person whom he believed to be Jansen leave a residence carrying two white bags of garbage. The associate obtained one of the bags from the street and brought it to the investigator, who extracted several bottles and cans. The items were placed in plastic bags and marked for evidence. They were then turned over to Brian G.D. Wraxall,

Page 115

the executive director, chief forensic serologist, and technical leader of Serological Research Institute. In an affidavit, Wraxall stated that he extracted, prepared, and analyzed samples of saliva taken from the bottles and cans in the garbage of the person whom the investigator had identified as Jansen. He positively identified DNA on the bottles and cans as belonging to the same person who was the secondary DNA source on the barrette. Wraxall concluded that the primary donor was Kincaid, and the secondary donor was Jansen. [Note 8]

To avoid any chain of custody problems involved in matching the DNA from the bottles and cans with the DNA on the barrette, Lampron filed a motion in the Superior Court for an order to compel Jansen to provide a buccal swab for DNA analysis. Both Jansen and the Commonwealth opposed Lampron's motion on the ground that the judge lacked the authority to enter such an order with respect to a private citizen. Following a hearing, the judge allowed the motion, concluding that, in accordance with Mass. R. Crim. P. 17 (a) (2), and pursuant to the standard set forth in Matter of a Grand Jury Investigation, 427 Mass. 221, 226, cert. denied sub nom. A.R. v. Massachusetts, 525 U.S. 873 (1998), Lampron had made the requisite showing that there was "a reasonable basis for believing ([]probable cause, if you wish)" that a buccal swab from Jansen would significantly aid Lampron's defense. [Note 9]

Jansen and the Commonwealth both now contend that the judge lacked any authority to compel Jansen, a third party not charged with any criminal offense, to submit to a buccal swab for DNA analysis at Lampron's request. As such, they argue that the judge's order must be reversed. We disagree.

Article 12 of the Declaration of Rights of the Massachusetts Constitution provides that "every subject shall have a right to

Page 116

produce all proofs, that may be favorable to him . . . and to be fully heard in his defen[s]e by himself, or his counsel, at his election." The express purpose of art. 12 is to give criminal defendants the right to present evidence that may be exculpatory. See Commonwealth v. Gagnon, 408 Mass. 185, 196 (1990). The Commonwealth has no obligation to collect evidence that may be helpful to a defendant. See Commonwealth v. Lapage, 435 Mass. 480, 488 (2001) ("While the prosecution remains obligated to disclose all exculpatory evidence in its possession, it is under no duty to gather evidence that may be potentially helpful to the defense"). Thus, a defendant has the constitutional right to present evidence at trial that some other individual may have committed the particular crime of which the defendant has been accused. See Commonwealth v. Conkey, 443 Mass. 60, 66 (2004), and cases cited; Commonwealth v. Harris, 395 Mass. 296, 300 (1985). The defendant must show that "the acts of the other person are so closely connected in point of time and method of operation as to cast doubt upon the identification of [the] defendant as the person who committed the crime." Commonwealth v. Hunter, 426 Mass. 715, 716-717 (1998), quoting Commonwealth v. Keizer, 377 Mass. 264, 267 (1979). Here, the means by which Lampron intends to make such a showing is a buccal swab from Jansen that, he expects, will provide exculpatory DNA evidence.

The source of the judge's authority to enter an order compelling Jansen to provide a buccal swab flows from rule 17 (a) (2) and our common law. Rule 17 (a) (2) provides that "[a] summons may . . . command the person to whom it is directed to produce the books, papers, documents, or other objects designated therein" (emphasis added). [Note 10] In Commonwealth v. Lampron, 441 Mass. 265, 270 (2004), we stated that "[a] judge's power under rule 17 (a) (2) includes the power to direct a nonparty to produce documentary evidence [or objects] prior to trial to allow the parties to inspect such documents or objects in preparation of trial." See Commonwealth v. Oliveira,

Page 117

438 Mass. 325, 339 n.15 (2002) (rule 17 [a] [2] permits defendant to summons objects from third party). See also K.B. Smith, Criminal Practice and Procedure § 1559 (2d ed. 1983 & Supp. 2004). Contrary to Jansen's unsupported assertion, we conclude that saliva is an "object" in the possession of a third party. See State v. Little, 249 Or. 297, 307 (1967), cert. denied, 390 U.S. 955 (1968) (bodily substances, including blood, hair, and saliva, are tangible "objects"). See also Webster's Third New Int'l Dictionary 1555 (1993) ("object" is "a discrete visible or tangible thing"). Cf. Fathke v. State, 951 P.2d 1226, 1228 (Alaska Ct. App. 1998) (palm print and fingerprints easily viewed as "objects").

We have stated that a summons issued pursuant to rule 17 (a) (2) is not a discovery tool, see Commonwealth v. Lampron, supra at 269, and it may not be used to subvert the pretrial discovery provisions of Mass. R. Crim. P. 14, 378 Mass. 874 (1978). [Note 11] See Mass. R. Crim. P. 17 (a) (2). See also Commonwealth v. Oliveira, supra. Rule 17 (a) (2) is intended to expedite trial proceedings by avoiding delays caused when counsel undertakes the task of examining documents or objects produced in response to a summons. See Commonwealth v. Lampron, supra at 270. See also K.B. Smith, Criminal Practice and Procedure, supra. Here, the judge's order requiring Jansen to provide a buccal swab in advance of trial comports with the intent of rule 17 (a) (2) by avoiding the inevitable, and perhaps prolonged, delay of waiting for a laboratory to prepare and

Page 118

analyze Jansen's saliva for DNA comparison purposes once Lampron's trial has started. [Note 12]

Before any books, papers, documents, or objects can be summonsed from a nonparty pursuant to rule 17 (a) (2), the defendant must make a factual showing that they are relevant and have evidentiary value to his defense. See Commonwealth v. Lampron, supra at 266-267, 269 (defendant may obtain order requiring production of treatment records of alleged rape victim where records contain information relating to issues of consent, state of mind, and motive to fabricate); Commonwealth v. Wanis, 426 Mass. 639, 643-645 (1998) (defendant may obtain order requiring production of records from police internal affairs division where information is relevant to material issue in criminal proceedings and could be beneficial to defense). This standard comports with the Federal analogue of rule 17 (a) (2), Fed. R. Crim. P. 17(c), on which our rule was modeled. See Commonwealth v. Lampron, supra at 269-270; Matter of a Grand Jury Subpoena, 411 Mass. 489, 500-501 (1992). See also United States v. Nixon, 418 U.S. 683, 699-700 (1974) (articulating test for compulsory production of material prior to trial pursuant to subpoena). "Potential relevance and conclusory statements regarding relevance are insufficient for a Federal rule 17 subpoena." Commonwealth v. Lampron, supra at 269, citing United States v. Jackson, 115 F.R.D. 664, 667-669 (D. Kan. 1994). Rule 17 (a) (2) also provides that the summons to a third party must not be "unreasonable or oppressive." See Commonwealth v. Oliveira, supra at 340. The decision whether documentary evidence and objects should be produced prior to trial under rule 17 (a) (2) is reserved to the sound discretion of the judge. See Commonwealth v. Lampron, supra at 271, citing Commonwealth v. Wanis, supra at 642.

Here, Jansen's DNA has significant relevance and evidentiary value to Lampron's defense. Lampron has shown that DNA testing performed by Wraxall indicated the clear presence of Jansen's DNA on the barrette and, in Wraxall's opinion, the

Page 119

absence of DNA that could be conclusively matched to Lampron. Without commenting on the strength or weakness of the Commonwealth's evidence against Lampron as a whole, the exculpatory value of this factual showing cannot be minimized or deemed inconsequential. Thus, in light of the possible chain of custody issue, a buccal swab from Jansen, in advance of trial, is critical to the preparation of Lampron's defense against charges of aggravated rape. Moreover, we conclude that the buccal swab test, in these circumstances, is reasonable. See Doe v. Senechal, 431 Mass. 78, 85, cert. denied, 531 U.S. 825 (2000) (buccal swab test reasonable where it will significantly aid in determination of paternity). See also Commonwealth v. Maxwell, 441 Mass. 773, 777 n.9 (2004) (because buccal swab test does not involve skin penetration, it is arguably less intrusive than taking of blood sample extracted by needle).

Contrary to the arguments raised by Jansen and the Commonwealth, the judge's order does not implicate Jansen's rights under the Fourth Amendment to the United States Constitution and art. 14 of the Massachusetts Declaration of Rights. Not every search and seizure has a constitutional dimension. See Commonwealth v. D'Onofrio, 396 Mass. 711, 714-715 (1986); Commonwealth v. Clegg, 61 Mass. App. Ct. 197, 203 (2004). The Fourth Amendment and art. 14 apply "to searches and seizures conducted by or at the direction of the State." District Attorney for the Plymouth Dist. v. Coffey, 386 Mass. 218, 221 (1982). "The constitutional analysis is triggered only when either the Federal or State government is significantly involved in the search, either participating in it or directing it in some way." Id. See generally J.A. Grasso & C.M. McEvoy, Suppression Matters Under Massachusetts Law § 3-3 (2004); 1 W.R. LaFave, Search and Seizure § 1.8 (4th ed. 2004). We recognize that a private individual may become an agent of the State, with constitutional implications, if government officials have instigated or participated in a search or seizure by that individual. See Commonwealth v. Leone, 386 Mass. 329, 333 (1982); Commonwealth v. Richmond, 379 Mass. 557, 561-562 (1980); Commonwealth v. McCambridge, 44 Mass. App. Ct. 285, 289 (1998). See also Coolidge v. New Hampshire, 403 U.S. 443, 487 (1971) ("The test . . . is whether [a private

Page 120

individual], in light of all the circumstances of the case, must be regarded as having acted as an 'instrument' or agent of the [S]tate"). That has not happened in this case.

Here, there simply has been no governmental involvement in the procurement of Jansen's DNA by Lampron. Quite to the contrary, the Commonwealth has advocated vigorously against Lampron's efforts to obtain a buccal swab from Jansen. Lampron is not seeking Jansen's DNA at the behest of the Commonwealth in order to advance a criminal prosecution. Rather, Lampron, acting in a private capacity, is furthering his own ends by attempting to secure all favorable proofs in advance of trial which, as he has shown, will significantly aid in the preparation of his defense by demonstrating a lack of physical evidence to support the charges against him. See Hooper v. Sachs, 618 F. Supp. 963, 968 (D. Md. 1985), aff'd, 823 F.2d 547 (4th Cir.), cert. denied, 484 U.S. 954 (1987) (where purpose of private citizen in conducting search pursuant to discovery order is to further individual interest, search retains its private character and is not subject to Fourth Amendment strictures). Cf. Doe v. Senechal, supra at 84-85 (Fourth Amendment has no application to private litigants seeking to obtain buccal swab paternity test in civil action). The Fourth Amendment and art. 14 have no application in the present context. [Note 13]

We make a final observation as to any future action by the Commonwealth to obtain a buccal swab from Jansen. As we have discussed, the Commonwealth's efforts in this regard, constituting governmental action, would implicate the Fourth Amendment and art. 14. See District Attorney for the Plymouth Dist. v. Coffey, supra at 221. The procedures with which the Commonwealth must comply in order to satisfy constitutional muster will vary depending on the stage of the proceedings at

Page 121

which a buccal swab is sought. Before an individual has been charged, we have concluded that a search warrant for a blood sample can be issued only on a showing of probable cause that the subject of the warrant committed a crime and that the evidence sought would aid in its investigation. See Matter of Lavigne, 418 Mass. 831, 835-836 (1994). At this stage, we also have stated that "in deciding whether to order an extraction of blood, the judge 'must weigh the seriousness of the crime, the importance of the evidence to the investigation and the unavailability of less intrusive means of obtaining it, on the one hand, against concern for the suspect's constitutional right to be free from bodily intrusion on the other.' " Id. at 836, quoting Matter of an Investigation into the Death of Abe A., 56 N.Y.2d 288, 291 (1982). Once a grand jury investigation has begun, such evidence may be compelled only if the grand jury have "a reasonable basis for believing (have probable cause for believing, if you wish) that a blood sample will provide test results that will significantly aid . . . in their investigation of circumstances in which there is good reason to believe a crime has been committed." Matter of a Grand Jury Investigation, 427 Mass. 221, 226 (1998). See Commonwealth v. Williams, 439 Mass. 678, 682-683 (2003). Finally, once an individual has been indicted, a request for blood sample must be based on a showing that the "defendant's blood will probably produce evidence relevant to the question of the defendant's guilt." Commonwealth v. Trigones, 397 Mass. 633, 640 (1986). In each of these contexts, the individual from whom the sample is sought must be given notice and an opportunity to be heard. See Commonwealth v. Maxwell, supra at 778. [Note 14]

Order affirmed.
