Reporter and Photog Killing -- Suspect Shoots Himself ... Posted Chilling Videos as Police Chased

11:20 PM PT -- Williams has been pronounced dead at the hospital.

Bryce Williams -- the man who shot and killed a Virginia reporter and photographer -- turned a gun on himself, but survived the shooting.

Police say they found him with a pulse, but he's in critical condition. While police were chasing Williams -- aka Vester L. Flanagan -- he put up the videos on Facebook and Twitter. One of the clips shows him walking up to his victims. Another shows him firing the deadly shots at point blank range.

Twitter and FB almost immediately suspended his accounts.

Williams claims the shooting was retaliation for Alison Parker and Adam Ward reporting him to human resources. He's not specific about why. He also claims Alison had made racist comments.

WDBJ says Williams was hired in April 2012 and fired a year ago.
