Pennsylvania State Police received a tip just after 11 a.m. Tuesday that Steve Stephens' vehicle was spotted in the parking lot of a McDonald's in Erie, Penn., about 100 miles away from Cleveland, Ohio, where Robert Godwin Sr. was killed on Easter Sunday.
Stephens posted the violent video of himself shooting Godwin to Facebook, and it took them almost 2 hours to find and remove the footage.
The break in the case came when police received a tip that Stephens was at the McDonald's in Erie, in the northwestern corner of the state, about 100 miles east of Cleveland. The drive-thru worker thought she recognized Stephens and called police, restaurant owner Thomas DuCharme Jr. told the Erie Times-News.
"At a little after 11, state police officers received information that Stephens' white vehicle was parked in a McDonald's auto park", said Williams. "Steve eventually stopped his vehicle and as officers approached his auto, he took his own life".
Pennsylvania police said he shot himself with a handgun about a mile from the McDonald's following a low-speed pursuit - at under 50 miles (80 kilometres) per hour.
"The next thing I know, they're approaching the auto".
On Sunday afternoon, 74-year-old Robert Godwin Sr. was shot and killed in Cleveland while walking home from Easter dinner with his family. Stephens later posted the video of him shooting and killing Godwin on Facebook.
Authorities in Cleveland urged a nationwide debate on the issue of violence on social media and to find answers to the plague of gun crime rocking America.
Mr Zuckerberg said during his keynote speech at the company's F8 developer conference in California that the company's "next focus is to build community" and also to build "common ground" between users. "And we will keep doing all we can to prevent tragedies like this from happening". Facebook said it removed the video 23 minutes after learning of it.
Facebook took down the video, as well as others he posted, and disabled his account within a few hours.
"He just took his nuggets and said, 'I have to go, ' and he drove off", Sayers told The Times.
The employee took Stephens' money and waited for him to drive up to the next window before calling the police, DuCharme said.
Mr Godwin did not seem to recognise the name.
"In addition to encouraging Stephens to turn himself in, Debbie Godwin voiced her forgiveness, saying, "(Y) ou know what, I believe that God would give me the grace to even embrace this man. "Some have killed themselves after they ran", Elliott said.
In the footage Stephens pulls over in a vehicle on a street in Cleveland as he says: "Find me somebody to kill, gonna kill this guy right here".
