Cleveland police were still searching Monday for a man who they said filmed himself killing an elderly man, uploaded the video to Facebook and bragged about having committed many other homicides.

The suspect, identified as Steve Stephens, is considered armed and dangerous, police said after the homicide in northeast Cleveland near the Lake Erie shore.

“Suspect did broadcast the killing on Facebook Live and has claimed to have committed multiple other homicides which are yet to be verified,” the police said in a statement, referring to Facebook’s live-streaming video service.

Facebook later clarified that Stephens had posted a video, rather than broadcast live, although he had appeared on Facebook Live at one point in the day.

The video of the attack was on Facebook for about three hours before being removed.

Officers believe Stephens, who worked for a behavioural health agency, might be driving a white or cream-coloured sports utility vehicle.
