Cleveland police are searching for a man accused of shooting and killing a man live on Facebook Sunday afternoon.

This Facebook Live video still shows Steve Stephens, who is accused of broadcasting himself shooting and killing a man Sunday afternoon.Facebook
The shooting happened on East 93rd Street just south of the Interstate 90 in the city's Glenville neighborhood, Cleveland police spokeswoman Sgt. Jennifer Ciaccia said. The accused shooter, Steve Stephens, broadcast the shooting live on Facebook.
The video of the killing remained up on Facebook for nearly three hours before it was taken down. His page has also been deactivated.
Stephens, whose name on Facebook was "Stevie Steve," broadcast another video of himself about 3 p.m., claiming to have killed other people and talking on the phone admitting that he snapped and "messed up." Those killings have yet to be verified, Ciaccia said.
Stephens has also written several Facebook statuses saying his claims of the additional killings are real and saying he was shooting because of "Joy Lane."
Stephens is 6-feet 1-inch tall, weighs about 240 pounds and has a full beard. He was wearing a dark-striped polo shirt at the time of the shooting and the Facebook Live broadcasts.
Stephens is driving a white or cream-colored SUV and is considered armed and dangerous, Ciaccia said. Anyone who spots Stephens should immediately call 911 and not approach him.
This post will be updated when further details about the shooting becomes available.
Nothing about 15 people though but he does claim to have shot more than one person
