Original story:

The search for the man responsible for killing 74-year-old Robert Godwin Sr. and posting the murder on Facebook was still underway Tuesday, according to authorities. Steve Stephens’ last known location was Cleveland, Ohio, where the killing took place Sunday, but law enforcement urged people in Pennsylvania, New York, Indiana and Michigan to be on the lookout.

“This is what we would consider a national search for Steve,” Cleveland Police Chief Calvin Williams told reporters Monday. “So, we are not going to leave any stone unturned.”

Williams confirmed that a detective spoke to Stephens’ on his cellphone following the murder in an attempt to convince him to give himself up, though no other details regarding the call were given. Reports emerged of a “ping” from Stevens’ cell phone in Erie, Pennsylvania, about 100 miles east of Cleveland. Williams said he could not confirm such reports, while police in Erie said they had no knowledge of a “ping” in the area. Williams also said there was no concrete evidence that Stevens had left Ohio.

Godwin’s family said they wanted justice for their father in an interview with CNN’S Don Lemon Monday night.

“The man who videotaped my father getting shot stripped him of his dignity,” Godwin’s son, Robby Miller, told Lemon. “And to post it online for the whole world to see, I’m just angry. No, I don’t want that man to die. I want him brought to justice. I just want him brought to justice.”

Facebook confirmed it removed the original video depicting the murder, though copies had proliferated on the site and other social media. “We know we need to do better,” Facebook’s Global Operations Vice President Justin Osofsky said in a community post Monday.

“This is a horrific crime and we do not allow this kind of content on Facebook,” a spokeswoman for the company said in a statement Monday. “We work hard to keep a safe environment on Facebook and are in touch with law enforcement in emergencies where there are direct threats to physical safety.”
