PITTSFIELD -- A 64-year-old Pittsfield man received a state prison sentence on Monday for being found guilty of the same weapons charges as his 30-year-old son.

Gerald V. Gaetani of Bradford Street was ordered to serve concurrent 2 1/2 year state prison sentences by Berkshire Superior Court Judge Mary Lou Rup.

Following a two-day trial last week, a Superior Court jury deliberated about four hours before finding Gaetani guilty on Thursday.

Gerald V. Gaetani’s son, Justin C. Gaetani, of Pittsfield, is serving a five- to eight-year state prison sentence on the same charges. The younger Gaetani turned down on a plea deal for a two-year jail sentence and was found guilty in April following a jury trial.

According to trial testimony, Pittsfield Police found a small arsenal of weapons in the elder Gaetani’s apartment where they had gone to look for his son who was wanted in connection with a vandalism incident in Dalton.

During his father’s trial, Justin Gaetani testified that he had moved the guns and ammunition to his father’s apartment.

Gerald Gaetani was found guilty of three counts of illegal possession of a large capacity weapon; 12 counts of illegal possession of a large capacity feeding device; single counts of illegal ownership of a firearm, rifle or shotgun, and possession of ammunition without a Firearms Identification Card; three counts of improper storage of a large capacity firearm; and one count of improper storage of a firearm.

Gaetani was given the state prison sentences for the illegal possession of a large capacity weapon and illegal possession of a large capacity feeding device charges. He was given a concurrent jail sentence on the other charges.
