REPORTER AND PHOTOGRAPHER KILLED ON LIVE TV

Police have identified a reporter as the suspect who allegedly killed two of his former colleagues on live television this morning in Virginia.

Vester Lee Flanagan, who is known professionally as Bryce Williams, has been identified as the suspect by the Augusta County Sheriff's office.

Sometime between last night and this morning, ABC News received a fax from someone who says he is Bryce Williams. It is a lengthy document – 23 pages. ABC News has turned it over to authorities.

Alison Parker, 24, and Adam Ward, 27, were killed in the field during a live news segment in Moneta, Virginia, according to their station, WDBJ-TV, a CBS affiliate serving the Roanoke-Lynchburg television market.

A third person was injured in the shooting, sources familiar with the situation said. Virginia Gov. Terry McAuliffe described the unnamed alleged gunman in a radio interview as a disgruntled employee of the station whom police are currently pursuing, adding that an arrest was "imminent."

The shooting was reported at 6:45 a.m. and the Franklin County sheriff confirmed that it is considered an active-shooter situation, adding that the suspect is believed to be male.

Franklin County school officials said three schools are on lockdown in the area of the shooting and that police officers are offering additional security.

Neighboring Bedford County Public Schools said, "We have placed all schools on perimeter lockdown status following a shooting in Franklin County this morning. This is a precautionary measure suggested by law enforcement."

The shooting itself took place at Bridgewater Plaza, a recreational facility with shops, restaurants, a mini golf course and boat rentals, where Parker and Ward were reporting on tourism.

WDBJ president and general manager Jeffrey A. Marks went on air this morning confirming the two deaths and noting that both victims were in relationships with other staffers at the station. Chris Hurst, who was dating Parker, posted tributes on his Twitter feed:

Marks said it was his "very very sad duty" to report their deaths, and noted that the shooting is under investigation. "We have other members of the team with us today holding back tears, frankly," Marks said.

He said Parker was a graduate of James Madison University in Harrisonburg, Virginia, while Ward was a graduate of Virginia Tech in Blacksburg, Virginia.

Marks and the anchors confirmed on air that Ward's fiancee was a morning producer at the station who was celebrating her last day at work today before starting a new job. Parker reportedly brought in balloons as part of the celebration before going out for the fatal live report.

Jay Webb, the news director at ABC affiliate station WHSV-TV in Harrisonburg (about two hours away) who had previously worked at WDBJ for several years, said he knew both victims. "Unthinkable," he told ABC News this morning, adding that he was especially close to Ward. "It’s a very hard time in our newsroom here this morning, as it is, I’m sure, across newsrooms across the country this morning."

He said he also knew Parker because she recently interned at his station before getting the job at WDBJ, which is owned by Schurz Communications of South Bend, Indiana.

"Alison was vibrant," he said. "Both extremely good people, will be missed."

The FBI's Roanoke office, a satellite of its field office in Richmond, is sending agents to the scene, the agency said.

Meanwhile, the New York Police Department, as a precaution, said it is moving critical-response vehicles to television stations across the city.
