A mentally ill man was caught on video being viciously pummeled by a prison guard who switched off his body cam before the beating began. In the March incident, Terrance Debose, 47, was tied to a chair in a Cuyahoga County Jail cell in Cleveland, Ohio, when Corrections Cpl. Nicholas Evans started beating the restrained man. Another corrections officer, Timothy Dugan, also punched Debose before the video ended.
