A former prison guard convicted of first-degree manslaughter in the death of Robert Brooks at Marcy Correctional Facility has been transfered from New York state custody to an out-of-state prison, the New York State Department of Corrections and Community Supervision (DOCCS) said Tuesday.

Nicholas Anzalone, who pleaded guilty to the charge and was sentenced in November to a 22-year prison sentence and five years of post-release supervision, was moved out of New York on March 5, DOCCS confirmed. 

“DOCCS determined that his continued placement in a New York State facility posed significant safety and security concerns for the individual, correctional staff, and the broader incarcerated population,” DOCCS said in a statement.

The state made the transfer under the Interstate Corrections Compact, which permits participating states to transfer incarcerated individuals under specified circumstances. Transfers are considered on a case-by-case basis following a review of multiple factors by the involved states.

Brooks, 43, died from compression of the neck and internal injuries at 3:52 a.m. Dec. 10, nearly seven hours after he arrived at Marcy from nearby Mohawk Correctional Facility prison, according to the medical examiner in the case. His death was ruled a homicide. The beating was inadvertently captured on body-cameras worn by correction officers, providing prosecutors key evidence in the case.Â
