Stephens was accused of shooting 74-year-old Robert Godwin Sr.in Cleveland on Sunday and uploading a video of the murder to Facebook.
Pennsylvania State Police troopers, joined by officers from the borough of Wesleyville, chased Stephens for about a mile along Buffalo Road, the state police said. She said the chase slowed suddenly from 50 miles per hour to about 20 miles per hour when the road narrowed from four lanes to two.One of the pursuing troopers picked his spot - in front of an abandoned school - and hit Stephens' bumper to get him to stop. Williams added that police "wanted to bring him in safely" so they could talk to him to try to understand his motives.
Seventy-four-year-old Robert Godwin Sr. was gunned down Sunday afternoon while he was collecting aluminum cans, shortly after he had been with some of his children for Easter.
The incident was the latest grisly crime posted on Facebook, reviving questions about videos posted on the world's largest social network, and how - or if - they can be monitored.
"We have a lot more to do", Mark Zuckerberg said.
"She's the reason why this is about to happen to you", Stephens said on a video posted on Facebook. He said he "just snapped". "One thing I do want to say, is that I forgive [the killer]".More news: Cavs hold off Pacers in Game 2
"I'm not happy he's dead at all, not at all".
Stephens pulled up to the next window, where restaurant owner Thomas DuCharme and a supervisor tried stalling him by telling him his fries were delayed. "We were just trying to make sure [the employee] got in contact with the state police". Authorities say Stephens shot and killed himself during the pursuit.
The Godwin sisters told Lane that none of this was her fault and that they don't hold any animosity for her.
On Tuesday morning, Stephens took his own life inside his auto in Erie, Pennsylvania. His vehicle did a half-turn and came to rest against the curb, and she heard a gunshot, she said.
Facebook said it removed the video of the shooting 23 minutes after learning of it. "We prioritize reports with serious safety implications for our community, and are working on making that review process go even faster".
