CLEVELAND -- Cleveland police say investigators were in contact via cellphone with a suspect who they say fatally shot an elderly man in a gruesome video posted on Facebook.

Police and the FBI in Cleveland said Monday that the suspect, 37-year-old Steve Stephens, could still be in the city or in surrounding states. Late Sunday, police issued an aggravated murder warrant for him and said in a statement that he may have traveled out of state. The search has expanded to other states, and residents of Pennsylvania, New York, Indiana, Michigan and Ohio, in particular, were asked to be on the alert.

Chief Calvin Williams says detectives talked with Stephens by cellphone Sunday after he shot 74-year-old Robert Godwin Sr. but haven’t had contact since.

“Early in this investigation we did have contact with him, direct contact,” Williams said. “The detectives did of course try to convince him to turn himself in and of course that hasn’t happened to date.”

Williams wouldn’t detail Stephens’ demeanor while on the phone with investigators.

“Obviously he’s got deep, deep issues,” Williams said. “Whether he was calm or not, he committed a heinous crime in this city.”

Williams stressed that investigators don’t know where Stephens is and said his last known location was at the scene of the Cleveland slaying. Williams urged Stephens to turn himself in, but said if he doesn’t, “We’ll find him.”  http://www.cbsnews.com/news/steve-stephens-facebook-killing-suspect-was-in-contact-with-cops-via-cell-chief-says/?ftag=CNM-00-10aab8a&linkId=36583672
