New York’s attorney general has appointed a special prosecutor in the death of a man who was beaten by state corrections officers.

New York State Attorney General Letitia James says her office is recusing itself from the investigation into the alleged beating that resulted in the death of an inmate in Upstate New York.

The state prison inmate died Dec. 10 after being beaten by correction officers at Marcy Correctional Facility in Oneida County.

The New York attorney general's office released new police body-worn camera video Friday as part of its investigation into the fatal beating of inmate Robert Brooks at the Marcy Correctional Facility upstate.

Inside Marcy Correctional Facility, the news of Robert Brooks’ death – while undeniably tragic – did not come as a complete shock, one inmate told CNN.

The New York attorney general’s office has recused itself from the high-profile case involving the beating death of state prisoner Robert Brooks due to an internal conflict, officials said on Thursday. Four corrections officers under investigation are currently represented by attorneys from the attorney general’s office in other cases.

Three of the officers involved in a fatal beating of Robert Brooks, a handcuffed inmate at the Marcy Correctional Facility upstate New York, were previously accused of abuse and assault, according to court documents obtained by CNN.

Some of the Corrections Officers involved in the death of Robert Brooks have previous complaints and lawsuits on their record.
