In a separate video, Stephens claimed to have killed more than a dozen other people.

An Ohio man shot dead an elderly person on Sunday afternoon and streamed the murder on FaceBook.

Steve Stephens claimed to be angry at a woman while committing the coldblooded killing and using the social networking site to broadcast it. Stephens is at large and police have urged the suspect to turn himself in.

Cleveland Police chief Calvin Williams said officers were searching for him in the Cleveland area and beyond.

The victim was identified as 74-year-old Robert Goodwin Sr.

In the video, which appears shaky, Stephens gets out of his car and appears to randomly target Goodwin, who was holding a shopping bag. Stephens says the name of a woman, whom Goodwin does not seem to recognize.

“She’s the reason that this is about to happen to you,” Stephens told Goodwin before pointing a gun at him. Goodwin can be seen shielding his face with the shopping bag.

Mayor asks him to surrender

Cleveland Mayor Frank Jackson publicly urged Stephens to turn himself in to police and not to “do any more harm to anybody.”

“Any problems he is having, we can have a conversation,” Mr. Jackson said.

In a separate video, Stephens claims to have killed more than a dozen other people. Mr. Williams said police have not verified any other shootings or deaths. “There are no more victims that we know are tied to him,” he said.

They’ve been talking with family and friends of Stephens, who is employed at Beech Brook, a behavioral health agency headquartered in Pepper Pike, near Cleveland, he said.

‘We are shocked’

“We are shocked and horrified and we don’t know anything more about it,” agency spokeswoman Nancy Kortemeyer told WOIO-TV. “We hope and pray that he is arrested as soon as possible and we hope and pray for a resolution quickly.”

It was not immediately known what Stephens does for the agency, which has said it will serve more than 18,000 children and families this year, according to its website.

The authorities said Stephens broadcast the video live on the social media network Sunday afternoon. It was up for about three hours before it was removed. His Facebook page also has been removed.

Spate of such incidents

This is not the first time Facebook Live has been used to broadcast violence or death. In January, four people in Chicago were arrested after they allegedly beat and taunted a mentally disabled man live on the social media site. Then in March, a 15-year-old Chicago girl was apparently sexually assaulted by five or six men or boys on Facebook Live, and none of the roughly 40 people who watched the live video reported the attack to police, authorities said.

“This is a horrific crime and we do not allow this kind of content on Facebook,” said a spokesperson for Facebook. “We work hard to keep a safe environment on Facebook, and are in touch with law enforcement in emergencies when there are direct threats to physical safety.”

Police say Stephens should be considered armed and dangerous.

The FBI is assisting in the investigation.
