The gunman in the shooting deaths of two television journalists in Virginia on Wednesday was a veteran anchorman with a history of workplace grievances, his former employer, Virginia's WDBJ said on Thursday. Vester Flanagan, 41, who went on the air under the name Bryce Williams, was a former employee of WDBJ7 in Virginia, where both of the slain journalists worked. He shot himself as police pursued him on a Virginia highway hours after the shooting. Flanagan, who was African-American, died later at a hospital, police said. Earlier on Wednesday, the journalists, who were both white, were shot dead during a live television broadcast. Hours after the shooting, someone claiming to have filmed it posted video online. The videos were posted to a Twitter account and on Facebook by a man identifying himself as Bryce Williams. The videos were removed shortly afterward. In one video, a handgun was clearly visible as the person filming approached the female reporter. He graduated from San Francisco State University in 1995 with a degree in radio and television, the school confirmed. According to a Facebook page believed to belong to the suspect, he was originally from Oakland, California, but most recently living in Roanoke, Virginia, where WDBJ7 broadcasts. There, he gained a reputation as someone who was difficult to work with because of his anger, station manager Jeff Marks said during a live broadcast. On February 1st 2013, two news managers and the HR manager notified Flanagan of the decision to terminate his employment. He reacted angrily, telling them that they would have to call the police, because he was going to make a 'stink' and it was going to be in the headlines, station General Manager Jeff Marks said. On the way out, he handed a wooden cross to the news director... and he said, you'll need this, Marks added.
