Edition: 2009
Statute: G.L. c. 269, § 11C
The Commonwealth must prove three things beyond a reasonable doubt:
Every firearm must bear a serial number permanently inscribed on a visible metal area. Commonwealth need not prove every part of the number was physically damaged; must prove some part was intentionally damaged.
Specific intent required: Jury must be instructed on specific intent (Instruction 3.120).
If jury finds defendant possessed a firearm with a defaced serial number, they are permitted (but not required) to accept that as sufficient proof that defendant was the person who caused the damage. If there is contrary evidence, possession testimony is weighed like any other evidence. See Instruction 3.260 (Prima Facie Evidence).
Rupp, 57 Mass. App. Ct. 377, 386 (2003).
The Commonwealth must prove five things beyond a reasonable doubt:
"Received" defined: Knowingly took custody or control. Not necessary that defendant personally possessed it, as long as they knowingly exerted control. Mere presence not enough; Commonwealth must prove knowledge, power, and intent to control.
If jury finds defendant knowingly received a firearm with defaced serial number, permitted to accept that as sufficient proof that defendant knew of the defacement. Weigh against contrary evidence.
