Victor Nieves was found guilty by a jury of six of knowingly having in his possession or under his control in a vehicle a firearm without a license, in violation of G. L. c. 269, § 10(a). On appeal, Nieves argues — we think persuasively — that the trial judge erred in denying his motion for a required finding of not guilty on the ground that the evidence was insufficient to enable the jury to find beyond a reasonable doubt that the gun was a working firearm, capable of discharging a bullet. Accordingly, we reverse the judgment.
“To constitute a ‘firearm’ within the meaning of G. L. c. 140, § 121, and hence within the prohibition of G. L. c. 269, § 10(a), the ‘instrument in question must be (1) a weapon, (2) capable of discharging a shot or bullet, and (3) under a certain length.’ ” Commonwealth v. Raedy,
The burden on the Commonwealth in proving that the weapon is a firearm in the statutory sense is not a heavy one. It requires only that the Commonwealth present some competent evidence from which the jury reasonably can draw inferences that the weapon will fire. So, for example, testimony from an expert that a firing pin could easily be fashioned to make a weapon work as a submachine gun could take to the jury the question of fact whether the gun was a machine gun. Commonwealth v. Bartholomew,
Here, the only evidence that the Commonwealth presented was the gun itself. A proffer under G. L. c. 140, § 121A, of a certificate by a ballistics expert of the firearms identification section of the department of public safety was excluded on a defense objection in the course of a bench conference transcribed as “inaudible.”
Accordingly, we reverse the judgment under G. L. c. 269, § 10(a), set aside the verdict, and order entry of judgment for the defendant.
So ordered.
Notes
The exclusion of the § 121A certificate is puzzling, but the Commonwealth has not contested it in its responsive memorandum.
