Bruce McGregor Davis is an American convicted murderer and former member of the Manson Family cult, frequently described as Charles Manson's "right-hand man." Unlike some of the more infamous members of the group, Davis was not involved in the high-profile Sharon Tate or LaBianca murders. Instead, he was convicted for his role in the brutal 1969 killings of musician Gary Hinman and stuntman/ranch hand Donald "Shorty" Shea.
