A former Gilpin County sheriff’s deputy is under fire for assaulting and permanently blinding a Denver man in one eye during an arrest last year, according to a lawsuit filed Tuesday. Christopher Bustos is suing former Gilpin County sheriff’s deputy Filip Perry in Denver County District Court for his use of force and for violating Bustos’ constitutional protections against unreasonable searches and seizures, the lawsuit stated. On March 19, 2023, Perry approached a car that had been reported stolen after another officer noticed it parked in the garage of the Ameristar Casino in Blackhawk.
