The video allegedly published by Stephens was published to Facebook on Easter Sunday. The incident took place in the afternoon as the victim was walking home from Easter dinner with family in Cleveland. He had been collecting cans on his walk, and police believe he was randomly targeted.
Stephens has been on the run since the shooting, which was reported by several people who watched the video on Facebook.
Reports that he was seen in Philadelphia came into authorities around 1 p.m. Monday. They converged on Fairmount Park, WPVI said, but so far, no one has been found.
Stephens is a 37-year-old black man who works as a jobs counselor for teens and adults.
