BALTIMORE (AP) — A Maryland correctional officer charged in a federal prison brutality probe shirked his duty to stop the beating and get medical help for the badly injured prisoner, a prosecutor said in her opening statement Thursday.

Sgt. Josh Hummer contends, thought, that he saw no misconduct when he looked inside Kenneth Davis’ cell nearly six years ago at the medium-security Roxbury Correctional Institution near Hagerstown. All Hummer saw as he wandered by, looking for a pair of lost gloves, was an officer squatting down to talk to Davis, lying beneath his bunk with his face to the wall, defense attorney Clarke Ahlers told the U.S. District Court jury.
