State police gave chase and the suspect shot himself "as the vehicle was spinning out of control", police said. Williams added that police "wanted to bring him in safely" so they could talk to him to try to understand his motives.
Stephens drove off, leading police on a short chase. Stephens posted video of the crime on his Facebook page, then in a series of other live videos, claimed to have killed others.
The video, which was posted on Sunday by OH man Steve Stephens, showed the graphic murder of 74-year-old Robert Godwin Sr.
The company said it disabled Stephen's account within 23 minutes of receiving the first report about the video of the fatal shooting and two hours after receiving any report. "Our hearts go out to the family and friends of Robert Godwin Sr. and we have a lot of work.and we will keep doing all we can to prevent tragedies like this from happening".
The murder was later posted to the social media site by the killer, who was said to be distraught over a break-up with his girlfriend. He said he "just snapped".
In an interview with CNN, several of Godwin's children said they held no animosity toward Stephens, either.
"I'm not happy he's dead at all, not at all".
She said her father would be proud of their choice to forgive.
Pennsylvania State Police said that they had received a tip-off from workers at the fast food chain shortly after 11:00 on Tuesday.
Stephens stopped for a moment at a McDonald's drive through in Erie, Pennsylvania, where an employee noticed him. Acting on a tip from McDonald's employees, Pennsylvania state troopers spotted him leaving the restaurant and pursued him.
DuCharme said a supervisor went to the window and tried to stall Stephens by telling him that his order of fries would need more time to cook.
By the time he pulled out of the driveway and onto Buffalo Road, state police were behind him, DuCharme said. "We would prefer that it had not ended this way because there are a lot of questions, I'm sure, that not only the family, but the city in general would have had for Steve".
Stephens' vehicle sustained minor damage after a trooper couldn't stop in time and hit the auto, but no injuries to law enforcement were reported. The Ford Fusion did a half-turn and came to rest at the curb.
