A federal grand jury in Sacramento returned a two-count indictment Thursday against a 29-year-old Fairfield man and Hells Angels Motorcycle Club member, charging him with possessing a firearm with an obliterated or altered serial number and possessing an unregistered short-barreled shotgun, a federal official said.
Michael Mahoney is the third person to be indicted in the Eastern District of California based on an investigation into a brutal beating in the clubhouse for the Vallejo chapter.
The other two defendants — Jaime Alvarez of Vallejo and Dennis Killough Jr. of Vacaville, both 51— were indicted by a grand jury on May 27.
According to court documents, in October 2021, two different victims — both of whom were members of a different motorcycle club that is considered a “puppet,” or subordinate, club of the Hells Angels — were beaten by Mahoney, Alvarez, Killough, and other club members based on perceived infractions of the Hells Angels’ rules, U.S. Attorney Phillip A. Talbert said in a press statement.
Court records show that on Dec. 8, 2021, law enforcement officers executed a search warrant at Mahoney’s Fairfield home and found several firearms, including a Smith & Wesson .38-caliber revolver with a serial number that had been scratched off, as well as a Sears & Roebuck 12‑gauge shotgun with a barrel that had been sawed off to approximately 12.75 inches in length, he noted.
Mahoney had not registered his ownership of the shotgun with the National Firearms Registration and Transfer Record, as required by federal law, Talbert added.
