VACAVILLE, CA – Another member of the notorious Hells Angels Motorcycle Club is facing federal charges, this time for illegally possessing ammunition. Kenneth Caspers Jr., 55, of Vacaville, was indicted by a grand jury this week, adding to a growing list of arrests stemming from a brutal beating that occurred at the club’s Vallejo clubhouse in October 2021.
Caspers is the fourth individual to be indicted in connection with the assault, which targeted members of a rival motorcycle club considered a “puppet” club to the Hells Angels. Authorities allege Caspers, along with Jaime Alvarez, Dennis Killough Jr., and Michael Mahoney, participated in the beating, motivated by perceived violations of Hells Angels rules. The investigation, a multi-agency effort, has peeled back layers of violence and intimidation associated with the outlaw motorcycle gang.
The ATF, leading the federal probe, discovered the illegal ammunition during a search of Caspers’ Vacaville residence on December 8, 2021. Agents seized 18 rounds of .22‑caliber, .25‑caliber, and/or .38 caliber ammunition from Caspers’ bedroom and bathroom. Crucially, Caspers is a convicted felon, barred by law from possessing either firearms or ammunition. This isn’t his first offense; court records indicate a prior felony conviction for the very same crime.
If convicted of being a felon in possession of ammunition, Caspers faces a maximum sentence of 10 years in prison and a $250,000 fine. However, sentencing will be determined by the court, taking into account federal guidelines and other relevant factors. As with all criminal cases, Caspers is presumed innocent until proven guilty beyond a reasonable doubt. The government is being represented by Assistant U.S. Attorneys Aaron D. Pennekamp and Jason Hitt.
Meanwhile, the three other defendants indicted in the beating – Alvarez, Killough, and Mahoney – have already pleaded guilty and are awaiting sentencing. Alvarez is scheduled to appear in court on March 7, 2023, Killough on March 27, 2023, and Mahoney on May 2, 2023. Each faces a potential 10-year prison sentence and a $250,000 fine. The investigation involved a broad coalition of law enforcement agencies, including the Solano County District Attorney’s Office, Solano County Sheriff’s Office, Vacaville Police Department, Vallejo Police Department, Fairfield Police Department, and the FBI.
Federal officials have framed the case as part of “Project Safe Neighborhoods,” a nationwide initiative aimed at reducing violent crime and gun violence. The program emphasizes community partnerships and strategic enforcement. While the Hells Angels have long operated in the shadows, this latest indictment underscores a renewed federal focus on dismantling their criminal activities and bringing those responsible for violence to justice. The case highlights the continued threat posed by organized crime groups and the dedication of law enforcement to protecting communities.
