Cleveland police are searching for a man who they say broadcast a killing on Facebook Live on Sunday. The person is Steve Stephens, a member of “the assertive community treatment team” at Beech Brook, a mental health organization in northeast Ohio. He is said to have driven up to an elderly man and shot him while broadcasting his moves and intent to kill as he went along. Stephens is described as 6-foot-1, 244 pounds and bald with a full beard. He is wearing a dark blue and gray- or black-striped polo shirt and believed to be driving a white- or cream-colored vehicle, according to police.
