COMMONWEALTH vs. JASON BARBOSA.

CYPHER, J. The defendant, Jason Barbosa, was convicted by a Superior Court jury in June, 2008, of unlawfully having a firearm under his control in a motor vehicle, G. L. c. 269, § 10(a); unlawful possession of ammunition, G. L. c. 269, § 10(h)(1); and possession of marijuana, G. L. c. 94C, § 34. In the following jury-waived trial, the defendant was found guilty of the subsequent offender charges related to the firearm and marijuana convictions. [Note 1] On appeal, the defendant argues that the evidence was insufficient to prove that he had knowledge or control of the firearm. He also challenges the Commonwealth's reliance on drug analysis certificates for the marijuana and the ballistics certificate for the revolver, invoking the principles established in Melendez-Diaz v. Massachusetts, 129 S. Ct. 2527 (2009). [Note 2] We reverse the defendant's conviction of possession of marijuana, and we affirm the convictions of possession of a firearm and ammunition.

Facts. Situated in a cruiser in an emergency cut-out on route 24 in Randolph at about 8:50 P.M. on December 8, 2006, State police Troopers Robert Lima and Michael Guerriero stopped a car driven by the defendant. They had observed the car swerving from one side of the middle lane to the other, high-beam headlights flashing, and, as it passed them, they noticed that the car had no front license plate. As they caught up to the car, they observed the car's dark tinted windows and altered exhaust. As the car stopped, they saw that one of the right rear lights was not working.

Trooper Lima approached the driver's side, with Trooper Guerriero behind him, and asked for the defendant's license and registration. The defendant was alone in the car. Trooper Lima detected an odor of marijuana. Trooper Lima described the defendant as being very nervous and fidgety during the brief conversation when the defendant produced his license and the

Page 342

car's registration. [Note 3] To determine whether the dark tinted windows were within legal limits, Trooper Lima took a test instrument from the cruiser and went back to the car on the passenger side, where he found that window lowered, conducted the test, and determined that the light transmitted was above the minimum requirement. He intended to test a rear window which appeared darker, but was told the rear windows could not be lowered. Trooper Lima also noticed that the odor of marijuana was stronger than he had previously detected. The defendant appeared more nervous and turned his body ninety degrees, looking into the rear seat a couple of times.

Trooper Lima asked whether he could search the interior of the car. The defendant gave permission and said that he would stand outside. When the defendant got out of his car, Trooper Lima pat frisked him and found a BlackBerry Smartphone cellular telephone in one pants pocket and a cylindrical metal object in the other. Trooper Lima recognized this as a grinder -- a device for shredding marijuana -- and observed what he believed to be particles of marijuana in the grinder. For his safety, and because it was cold, Trooper Lima placed the defendant in the back seat of the cruiser, telling him he was not under arrest.

Trooper Guerriero then carried out a detailed search of the interior of the car. He found a plastic bag of what he thought was marijuana and a number of empty plastic bags inside the boot covering the gear shift lever. Trooper Guerriero found a loaded revolver under the rear seat when, intending to look under the seat, he lifted it slightly and it "spr[a]ng forward and went upright." The defendant then was handcuffed and arrested. 1. Possession of the firearm. The defendant argues that the evidence was insufficient to prove knowledge, dominion, or control over the revolver and ammunition. We examine whether the evidence, viewed according to the familiar standard set forth in Commonwealth v. Latimore, 378 Mass. 671 , 677-678 (1979), was sufficient for the jury to find beyond a reasonable doubt that he constructively possessed the revolver. Constructive possession requires proof that the defendant had "knowledge coupled with the ability and intention to exercise dominion and control

Page 343

[internal citations omitted]." Commonwealth v. Brzezinski, 405 Mass. 401 , 409 (1989). Knowledge may be proved by circumstantial evidence. Commonwealth v. Sespedes, 442 Mass. 95 , 99 (2004), and cases cited.

The defendant was traveling alone in a car that he maintained and frequently operated, although it was registered to his mother. [Note 4] The defendant repeatedly glanced at the location of the firearm during the traffic stop. The defendant's mother denied ownership of the firearm. It is a reasonable inference that the revolver was purposefully hidden in a well under the rear seat, but was accessible with minimal difficulty because of the unusual folding action of the seat. [Note 5] Also, there were items in the car and in the trunk that appeared to be linked to the defendant: a number of compact discs (CDs) scattered in the car, male clothing and footwear, and a quantity of "homemade" CDs in the trunk. The jury reasonably could infer that the defendant knowingly had the revolver under his control. The motion for a required finding of not guilty properly was denied.

2. Drug analysis and ballistics certificates. The defendant argues that the holding of Melendez-Diaz v. Massachusetts, 129 S. Ct. 2527 (2009), that "[t]he Sixth Amendment does not permit the prosecution to prove its case via ex parte out-of-court affidavits," requires the reversal of his convictions. Id. at 2542. Although the defendant did not object to the introduction of the certificates on confrontation grounds, we review the constitutional issue as if it had been preserved by proper objection and determine whether the admission of the certificates was harmless beyond a reasonable doubt. Commonwealth v. Vasquez, 456 Mass. 350 , 352 (2010).

a. The marijuana. "[T]he Commonwealth must prove beyond a reasonable doubt 'that a substance is a particular drug' because such proof is an element of the crime charged." Commonwealth v. Vasquez, supra at 361, quoting from Commonwealth v. McGilvery, 74 Mass. App. Ct. 508 , 511 (2009). Where, as here,

Page 344

drug analysis certificates were erroneously admitted, "the Commonwealth must show that other properly admitted evidence of guilt is 'overwhelming,' in the sense that it is 'so powerful as to "nullify any effect" ' that the improperly admitted evidence 'might have had' on the fact finder or the findings. Commonwealth v. Tyree, [ 455 Mass. 676 ,] 704 n.44 [(2010)], quoting Commonwealth v. Dagraca, [ 447 Mass. 546 ,] 555 [(2006)]." Commonwealth v. Vasquez, supra at 362.

There was no evidence other than the certificate that the substance in the plastic bag seized from under the boot over the gearshift was marijuana. [Note 6] Trooper Lima read the portion of the certificate which stated that the "vegetable matter was found to contain [m]ari[j]uana." In the Commonwealth's opening statement, the prosecutor stated that the "evidence will show that the substance was tested at the state lab, and the substance was, in fact marijuana." There were numerous, matter-of-fact references to the substances as marijuana. The troopers did not open the plastic bag seized to conduct any field tests, such as burning or smelling the raw substances. Although Trooper Lima testified that he smelled marijuana and observed what looked like marijuana when he approached the car, he did not at any time express an opinion based on any objective criteria, such as training or expertise. See Commonwealth v. Vasquez, supra at 365, quoting from Commonwealth v. Melendez-Diaz, 76 Mass. App. Ct. 229 , 233 (2010) ("admission of drug certificates not harmless beyond reasonable doubt where 'word "cocaine" frequently was used by the police, but at no time did the officers cite any objective evidence, criteria, or field tests; they did not articulate how their expertise permitted them to identify the

Page 345

substances as cocaine' "); Commonwealth v. Rodriguez, 76 Mass. App. Ct. 235 , 244 (2009) (testifying officer not asked to identify substance based on his experience as narcotics officer). See also Commonwealth v. Dawson, 399 Mass. 465 , 467 (1987). Contrast Commonwealth v. Madera, 76 Mass. App. Ct. 154 , 158 (2010) (detectives testified to their years of experience and training in narcotics). Accordingly, the admission of the drug certificates was not harmless beyond a reasonable doubt, and the defendant's conviction of possession of marijuana must be reversed.

b. The revolver. The holding in Melendez-Diaz applies to the ballistics certificate in this case. See Commonwealth v. Depina, 456 Mass. 238 , 248 (2010). See also Morales v. Massachusetts, 129 S. Ct. 2858 (2009). "The Commonwealth's burden to prove that a weapon is a 'firearm' in the statutory sense is not a heavy one. See Commonwealth v. Nieves, 43 Mass. App. Ct. 1 , 2 (1997). 'It requires only that the Commonwealth present some competent evidence from which the jury reasonably can draw inferences that the weapon will fire,' id., and that it is under a certain length. See G. L. c. 140, § 121 (definition of '[f]irearm')." Commonwealth v. Loadholt, 456 Mass. 411 , 430-431 (2010).

The evidence that the revolver would fire elicited at trial was as follows. Trooper Guerriero, who first saw the fully loaded gun, picked it up to determine if it was "authentic and not a replica." [Note 7] Concluding it was authentic, he replaced it in the well under the rear seat where he found it. Trooper Lima took the revolver and began the process for preserving evidence. He made the revolver safe, removing six rounds of ammunition and placing the ammunition and the revolver in plastic bags, and identified them for processing to the State police laboratory. Trooper Guerriero delivered them for analysis.

Subsequently, the revolver and five rounds of ammunition were returned with one "spent" round (or casing with the slug

Page 346

missing). Trooper Lima testified that it appeared that the laboratory test firing had been made with the "spent" round, explaining why the casing returned differed from the five live rounds that had been returned intact. He was asked, without objection, whether the revolver had been test fired and if there were any malfunctions. He replied "yes" and "[t]here were none," respectively, to these questions. He did not read from the ballistics certificate. [Note 8]

The ballistics certificate was not emphasized by the Commonwealth. In closing argument, defense counsel pointed out that the jury were not required to believe or accept the certificate. The Commonwealth did not refer to the certificate in its closing argument. The judge did instruct the jury that the certificate was prima facie evidence to be considered with all the evidence.

In determining whether, under these particular circumstances, the admission of the ballistics certificate was harmless beyond a reasonable doubt, we are guided by two cases, Commonwealth v. Depina, supra, and Commonwealth v. Pittman, 76 Mass. App. Ct. 905 (2010). In Depina, a gun found loaded with four live rounds and one "spent" casing was returned after examination by the State police firearms identification section with three spent casings and one live round. The police testified that the three spent rounds had been test fired. The "jury could reasonably infer that the State police had test fired the revolver using the live rounds." Id. at 250. The court concluded: "In view of this evidence, we are satisfied beyond a reasonable doubt that, even without the certificate, the evidence that the revolver was a working firearm . . . was overwhelming." Ibid. In Commonwealth v. Pittman, supra at 905, 907, a gun found fully loaded was submitted with two live rounds to the State police laboratory for testing. Local police testified that one round was used in test firing, and explained the difference between the live round and the empty casing returned. "[T]here

Page 347

was overwhelming evidence independent of the ballistics certificate that the gun in question was operable." Ibid. [Note 9]

In the present case, where the revolver was found loaded, the revolver and six live rounds were submitted for testing, five rounds were returned intact with one "spent" round, there was testimony explaining that evidence and the test firing, and there was a lack of emphasis on the certificates, we are constrained to conclude that the Commonwealth has established that the other evidence of guilt is so " 'overwhelming,' in the sense that it is 'so powerful as to "nullify any effect" ' that the improperly admitted evidence 'might have had' on the fact finder." Commonwealth v. Vasquez, supra at 362, quoting from Commonwealth v. Tyree, supra at 704 n.44.

c. The ammunition. "With respect to 'ammunition,' there is no requirement of current functionality. The Commonwealth need not prove that 'particular ammunition is capable of being fired'; it only must show that 'the putative ammunition is designed for that purpose.' " Commonwealth v. Loadholt, 456 Mass. at 431, quoting from Commonwealth v. Mendes, 44 Mass. App. Ct. 903 , 904 (1997). The evidence that the revolver was found loaded with bullets and that one round was used in test firing the revolver overwhelmingly proved that the ammunition was designed for use in a firearm. See Commonwealth v. Muniz, 456 Mass. 166 , 173 (2010). The admission of the ballistics certificate was harmless beyond a reasonable doubt.

Conclusion. On the indictment charging possession of marijuana, the judgment is reversed, and the verdict and subsequent offense finding are set aside. The remaining judgments are affirmed.

So ordered.
