Police said Stephens, 37, killed Robert Godwin Sr, 74, while the pensioner was collecting aluminium cans in Cleveland, Ohio. After what was reportedly a brief pursuit, Stephens turned a gun on himself. "There's two things. Either he's dead somewhere, or someone is holding him up somehwhere else".

Pennsylvania State Police said Steve Stephens was spotted Tuesday morning in Erie County, in the state's northwest corner.

"As the officers approached that vehicle Steve Stephens took his own life", he said.

Earlier, police warned that Stephens may have left the state of OH for Pennsylvania, New York, Indiana or MI. He said it looked like the man was shot in the head or in the ear area.

"It was a horrific crime - one that has no place on Facebook, and goes against our policies and everything we stand for", Facebook VP of Global Operations Justin Osofsky said in a blog post late Monday.

Within a day, authorities expanded the search nationwide and offered a $50,000 reward for information leading to his capture and prosecution.

"We're still asking Steve to turn himself in", said Williams.

"We would have preferred that it had not ended this way", Mr Williams added, saying he and the community would have had "a lot of questions" for Stephens.

Police earlier had said that Stephens had broadcast it on Facebook Live. Stephens' Facebook page also was eventually removed. His attorney at the time, Trent Binger, said today that he remembered Stephens discussing gambling problems. No one reported it, according to Facebook. A third video, showing the suspect declaring his intent to kill the victim, was uploaded to Facebook but not reported by users, and was discovered after the killing.

According to a timeline released by Facebook, Stevens first posted a video of himself announcing his plan to kill some and two minutes later posted a video of himself shooting and killing Godwin.

Stephens had worked since 2008 as a vocational specialist and youth mentor at Beech Brook, a behavioural health agency located outside Cleveland.

"I want him to know what he took from us".

In the interview, Miller and three other relatives - Godwin's former wife, Dorothy Crumpton and his daughters, Tammy Godwin and Naujia Godwin - described the victim as a good man and father. "My heart is just broke".

"I am relieved to know that he is off the street and that he can not hurt any other family", Haymon said.

Facebook CEO Mark Zuckerberg pauses as he delivers his keynote address during the 2011 Facebook f8 conference. However, Williams said those accounts were not set up by the family and there's no way to know where the money is going.
