Bruce Meyer, a college student, was found dead in the parking lot of his Brewster, New York, apartment building on December 14, 1975. The cause of death was five point-blank gunshot wounds to the head from a .22 caliber handgun fitted with a silencer.

Investigators linked Meyer’s killing to the Hells Angels Motorcycle Club and believed it was retaliatory. The case proved difficult to prosecute because of the group’s secretive nature, and no arrests have ever been made; the investigation later grew cold and remains open.
