BOSTON, MASSACHUSETTS – [DOJ MEDIA STATEMENT, NO BOOKING PHOTO PROVIDED] – A Hyannis man was sentenced yesterday for being a felon in possession of a firearm. Specifically, the defendant possessed and sold a Chinese SKS .762 caliber rifle.
Ryan Diefenbach, 33, was sentenced by U.S. Senior District Judge William G. Young to six years in prison to be followed by three years of supervised release. In July 2024, Diefenbach pleaded guilty to one count of being a felon in possession of a firearm. In November 2022, Diefenbach, along with co-defendant Donnell Pina, was indicted by a federal grand jury.
In September 2021, Diefenbach, and allegedly Pina, sold a Chinese SKS .762 caliber rifle to a confidential informant in Hyannis. Due to previous felony convictions, including prior convictions for carrying a firearm without a license, unlawfully possessing a firearm, possessing a firearm with a defaced serial number and assault with a dangerous weapon, Diefenbach was prohibited from possessing firearms.
At the time Diefenbach committed the offense, the charge of being a felon in possession provided for a sentence of up to 10 years in prison, up to three years of supervised release and a fine of up to $250,000.
Acting United States Attorney Joshua S. Levy and James M. Ferguson, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms & Explosives, Boston Field Division made the announcement today. Assistant United States Attorney Elianna J. Nuzum of the Major Crimes Unit is prosecuting the case.
