Revised: November 2021
Statute: G.L. c. 140, § 131L
The Commonwealth must prove three things beyond a reasonable doubt:
Standard definitions. Firearm: barrel less than 16 inches. Rifle: rifled bore, barrel 16+ inches. Shotgun: smooth bore, barrel 18+ inches, overall 26+ inches.
A weapon is not kept or stored when it is carried by the defendant or when it is under their immediate control.
"Carried" requires actual physical possession of the firearm. Reyes, 464 Mass. 245, 258 n.19 (2013); Patterson, 79 Mass. App. Ct. 316, 319 (2011).
"Under the control" requires that a person be sufficiently near the firearm to immediately prevent its unauthorized use. If not close enough to immediately prevent unauthorized use, one is not in control of it.
A firearm is unsecured when it is accessible to a person not authorized by law. A firearm is properly secured when it is either:
- Stored in a locked container; or
- Has an engaged tamper-resistant mechanical lock or other safety device.
A safety device is properly engaged if it renders the weapon inoperable by any person other than the owner or other lawfully authorized user. Cantelli, 83 Mass. App. Ct. 156 (2013).
