The death of a handcuffed man who was pummeled by New York prison guards was ruled a homicide in an autopsy report, lawyers for his family said Wednesday. The report issued by the county medical examiner's office last week concludes that the cause of Robert Brooks' death in December was compression of the neck and multiple blunt impact injuries. Body camera video shows corrections officers assaulting Brooks for about 10 minutes while he was handcuffed on a medical examination table at Marcy Correctional Facility on Dec. 9.
