The search for Steve Stephens is now a national manhunt.

Law enforcement officials across the country are continuing to look for Stephens, who is suspected of allegedly killing a stranger and posting a video of the homicide to Facebook Sunday.

At a Monday afternoon press conference, authorities said there is now a $50,000 reward for information leading to the arrest of the 37-year-old man. The FBI has placed Stephens on their 'Most Wanted' list.

Cleveland Police Chief Calvin Williams asked Stephens, who he referred to as Steve, to call a friend so the search could end peacefully.

An alleged spotting in Philadelphia earlier Monday afternoon was proven to not be accurate, officials said.

The victim has been identified as 74-year-old Robert Godwin, Sr.

If you see Stephens, do not approach him. He is considered to be armed and dangerous.
