CLEVELAND, OH (AP) -- A manhunt is underway for a suspect who police say killed a man on the street Sunday while streaming it live on Facebook.

Law enforcement is searching the Cleveland area and beyond for Steve Stephens, the suspect police say walked up to an elderly man and shot him while on video, said Cleveland Police Chief Calvin Williams.

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

Cleveland Mayor Frank Jackson publicly urged Stephens to turn himself into police and not to "do anymore harm to anybody."

"Any problems he is having, we can have a conversation," Jackson said.

In the video, Stephens claimed to have killed more than a dozen other people. Williams said police have not verified that information.

"There are no more victims that we know are tied to him," he added.

The chief also said they've been talking with Stephens' friends and family.

"What happened today was senseless," Williams said.

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

"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.

Williams said Stephens may be driving a newer model white Ford Fusion, possibly with a temporary license plate. He is described as a black man with a bald head and beard, standing 6 foot 1 inch and weighing 240 pounds. Anyone with information is asked to call 911.

ORIGINAL STORY 4/16/2017 @ 6:30 p.m.

CLEVELAND, OH (NBC NEWS) -- Cleveland police were searching Sunday for a man who they said killed a person live on 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. The FBI was providing assistance, a spokeswoman told NBC News.

Police said Sunday that the man "broadcast the killing on Facebook Live and has claimed to have committed multiple other homicides which are yet to be verified."

A series of posts Sunday on what authorities said was Stephens' Facebook page complained that he had "lost everything" to gambling. The posts named specific people whom the user wanted to talk to, and at one point he wrote "I killed 12 people today" and wouldn't stop until he could speak to his mother and a second woman.

Later, the user posted: "I killed 15 today because of [the second woman]." The user called it his "Easter day slaughter."

NBC News archived the posts before the account was removed. Police stressed that no other victims had been found.

Stephens was described as black, 6 feet, 1 inch tall, weighing 244 pounds and bald with a full beard. He was last seen wearing a black or dark blue and gray striped polo shirt and was driving a white Ford Fusion with temporary tags, authorities said.

As a precaution, students at Cleveland State University were told to shelter in place or stay away from the school.

No other information was immediately available.
