UPDATED: 3 p.m. ET

A news reporter and a cameraman were killed Wednesday morning in a shooting that was captured during a live TV broadcast outside of Roanoke, Virginia. Adding to the shock, the gunman then posted his own video of the shooting on Facebook and Twitter.

The shooting happened during a live report on WDBJ7, the local CBS affiliate. Morning reporter Alison Parker and her cameraman Adam Ward were shot dead. The woman they were interviewing was wounded.

Police then pursued the gunman, identified as Vester Flanagan, along Interstate 81, eventually taking him into custody more than three hours away after he had apparently shot himself. Flanagan died at around 1:30 p.m. at a nearby hospital, state police said.

But before his capture, Flanagan, using his on-air name Bryce Williams, apparently posted videos on Facebook and Twitter that showed the shooting from the gunman's perspective. He also tweeted accusations against "Alison" and "Adam."

Virginia Gov. Terry McAuliffe said earlier on Wednesday that the suspect was a "disgruntled employee."

Flanagan was a former reporter at WDBJ7, the station said. "About two years ago we had to separate him from the company," the station's general manager, Jeffrey A. Marks, told CNN. He said he couldn't remember any connection between Flanagan and the victims and wasn't sure whether they had overlapped at the station.

"He did make some accusations against people some time ago," Marks said. "You can never imagine that somebody's going to come back and act on those issues."

Meanwhile, ABC News said it had received a 23-page fax after the shooting Wednesday morning, apparently from Flanagan, and had turned it over to authorities.

In the document, the writer identifies himself as Bryce Williams, with the legal name of Vester Lee Flanagan II. Flanagan, who is black, says the Charleston church shooting in June triggered his outrage, and cites other mass shootings in the U.S. as inspirations.

The shooting occurred while Parker and Ward were at Bridgewater Plaza near Smith Mountain Lake, a reservoir community about 50 miles southeast of Roanoke. Parker was interviewing Vicki Gardner, head of the SML Chamber of Commerce, when the gunman fired off at least half a dozen shots.

Viewers heard screams and "Oh my God!" before the feed cut back to a visibly disturbed anchor in the newsroom, who said, "OK not sure what happened there. We will of course let you know as soon as we find out what those sounds were."

A screengrab from the video, which has since been removed from YouTube, showed the apparent shooter aiming the gun toward the cameraman just before the camera drops to the ground and the feed cuts.

The video, as seen on WDBJ7's live broadcast, spread quickly on the Internet, but most copies were just as quickly taken down. The videos that were apparently posted by Flanagan himself were also swiftly removed by social networks.

Gardner, who was being interviewed, was shot in the back. She was transported to a hospital where she underwent surgery and was in stable condition Wednesday afternoon.

Parker was 24; Ward was 27.

The station tweeted, "We love you, Alison and Adam."

Remembering the victims

Parker grew up in the area and is a former WDBJ7 intern. The James Madison University graduate previously worked at WCTI NewsChannel 12 in Jacksonville, North Carolina, according to a bio on the station's website. Ward graduated from Salem High School and Virginia Tech, the station said.

Viewers took to the news station's Facebook page to remember the journalists.

"I want to say I do not know any of you personally but I am so devastated by what happened," wrote Robin Rodenbaugh. "You all were really strong to keep it together on the air just now but I know you are shocked beyond belief. I'm so sorry this happened and to our community."

"My heart is breaking over the loss of Alison and Adam," wrote Nancy Martin Coleman. "I didn't know either personally, but they become part of our families and homes by watching them every day."

Chris Hurst, an anchor at WDBJ7, tweeted after the shooting that he and Parker were "in love" and had just moved in together. "We were together almost nine months. It was the best nine months of our lives. We wanted to get married. We just celebrated her 24th birthday," he said, calling her "the most radiant woman I ever met."

"I cannot tell you how much they were loved by the WDBJ7 team," said Parks, adding that "they both were in love with other members of the team here and our hearts are broken."
