The spokesperson added that the shooting itself was not broadcast on Facebook Live but was uploaded after the incident took place.
Stephens is a case manager at a behavioural health agency called Beech Brook from Pepper Pike, near Cleveland.
He helped the kids and young adults find career opportunities and prepare themselves for the working world, said Nancy Kortemeyer, senior director of marketing and public relations at Beech Brook.
Police reported getting dozens and dozens of tips, and nine schools in Philadelphia were locked down Monday while authorities investigated possible sightings of Stephens.
Police say Stephens killed 74-year-old Robert Godwin Sr.
As for the shooting victim, Godwin appeared to have been selected at random, gunned down while picking up aluminum cans Sunday afternoon after spending Easter with some of his children. In his last video, Stephen said he "snapped" and will continue killing until he is caught. No additional victims have been found, though officers are searching multiple locations, police said.
Godwin was a retired foundry worker and was apparently shot by Stephens while out collecting aluminium cans in a plastic shopping bag.
Local police are being aided by state and federal authorities, cleveland.com said. Anyone with information should call 911. Robert Godwin Jr. told WOIO about his father.More news: A 'Sci-Fi' Cancer Therapy Fights Brain Tumors, Study Finds

The shooter says a woman's name and asks Godwin to repeat it.
"Hopefully I'm gonna try to kill as many people as I can".
Meanwhile, law enforcement officials are warning residents in Pennsylvania, New York, Indiana and MI to be on the lookout for Stephens, who is still at large.
Police say Stephens should be considered armed and unsafe. Stephens is driving a white Ford Fusion with temporary license plates, according to Cleveland police.
This story has been corrected to show that Mayor Frank Jackson, not Police Chief Calvin Williams, urged Stephens to turn himself in and not to "do anymore harm to anybody".
As police continue to hunt for a man they suspect of allegedly broadcasting a homicide on Facebook Sunday, officials from the social network are calling it a "horrific crime".
Police and the Federal Bureau of Investigation in Cleveland said 37-year-old Steve Stephens could still be in the city or in surrounding states.
The video of the killing was up for about three hours before it was removed. She says he spent the day before the shooting doing one of the things he loved most, fishing in Lake Erie. No information about the victim has been released.
