A special prosecutor says he made offers to resolve criminal cases against 10 New York prison guards indicted in the beating death of a handcuffed man.

Six correctional officers were charged with murder last month in the December death of Robert Brooks, 43, whose brutal beating was captured on body-worn cameras. Three other prison employees were charged with manslaughter and another with evidence tampering.

The prosecutor’s offer to David Walters, charged with second-degree manslaughter, was to plead guilty to the existing charge with a recommendation for a mid-range sentence, his attorney Nick Passalacqua said.

Fitzpatrick also is investigating the death of Messiah Nantwi on March 1 at Mid-State Correctional Facility in Marcy. A court filing by the attorney general’s office said there is “probable cause to believe” that as many as nine correctional officers either caused or could be implicated in his death.
