During a press conference on Tuesday afternoon, Cleveland Police Chief Calvin Williams told reporters that Pennsylvania police had received a tip from someone who said they saw a white Ford Fusion, the vehicle police had said Stephens was driving, in a McDonald's parking lot.
After the horrific Cleveland shooting of 74-year-old Robert Godwin was posted to Facebook, the video remained for almost two hours before the social media company took it down.
Facebook boss Mark Zuckerberg has said the social network "has a lot of work to do" in order to prevent repeats of the Cleveland shooting of Robert Godwin Sr, after a video of his murder was shared on the site.
Troopers from the Pennsylvania State Police responded to the tip and Stephens sped away, police said.
"This started with one tragedy and ended with another person taking their own life", said Cleveland Police Chief Calvin Williams.
Facebook said Stephens' account was suspended within 23 minutes of the murder video being reported, but admitted it needs to "do better". Then, he posted video of the attack on his Facebook Page.
Godwin's daughter Brenda Haymon learned of Stephens' death as she was planning funeral arrangements for her father, according to CNN. Acting on a tip, Pennsylvania State Police spotted Stephens, 37, in Erie County, in the state's northwest corner, and went after him.
Stephens was found dead near Buffalo Road and Downing Avenue around 11:10 a.m., police said. In it, he said, "I snapped, I just snapped".
During the manhunt, Stephen D. Anthony, special agent in charge of the FBI in Cleveland, said, "There's not a federal agency in the United States that is not involved in some way". He had many traffic violations but no criminal record, Williams said.
As officers approached the area, Stephens took off in his vehicle. She said state troopers weren't far behind.
Police said it wasn't clear whether Stephens had any help while he was on the run or where he had been and that investigators will try to retrace his steps.
On Monday evening, Facebook announced that it was launching a review for reporting harmful content following the killing.
In interviews before Stephens' death, Godwin's relatives said they forgave his killer.
Seconds before the shooting, Stephens asked the victim to say the name of a woman believed to associated with the suspect.
Within a day, authorities expanded the search nationwide and offered a $50,000 reward for information leading to his capture.
Cleveland police say they are searching for a homicide suspect who broadcast the fatal shooting of another man live on Facebook.
