5 Things to Know This Morning

— -- Your look at five key topics related to Wednesday's shooting in Virginia.

1. Remembering the Victims

Reporter Alison Parker, 24, and cameraman Adam Ward, 27, were fatally shot Wednesday while filming a live television segment. The colleagues worked at WDBJ, a CBS affiliate serving the Roanoke-Lynchburg, Virginia television market.

2. Alleged Gunman Dead

A former reporter at the station, Vester Lee Flanagan II – known professionally as Bryce Williams – allegedly shot the co-workers. He later died of a self-inflicted gunshot wound, authorities said.

3. After Shooting, Alleged Gunman Details Grievances in ‘Suicide Notes’

A man claiming to be Bryce Williams called ABC News over the last few weeks, saying he wanted to pitch a story and wanted to fax information. He never told ABC News what the story was.

A fax was in the machine Wednesday (time stamped 8:26 a.m.) almost two hours after the shooting. A little after 10 a.m., he called again, and introduced himself as Bryce, but also said his legal name was Vester Lee Flanagan, and that he shot two people this morning. While on the phone, he said authorities are “after me,” and “all over the place.” He hung up. ABC News contacted authorities immediately and provided them with the fax.

In the 23-page document faxed to ABC News, the writer says “MY NAME IS BRYCE WILLIAMS” and his legal name is Vester Lee Flanagan II. He writes what triggered the carnage was his reaction to the racism of the Charleston church shooting:

4. Alleged History of Problems at Former TV Station

The trail of workplace rage that appears in part to have led a Virginia news reporter to shoot two colleagues on live television is meticulously -– even hauntingly -– laid out in a long series of memos filed as part of Flanagan’s lawsuit against his onetime employer.

5. Reflections From Loved Ones

Parker was dating another reporter at WDBJ-TV in Roanoke, Virginia, Chris Hurst.

In a series of tweets, Hurst described Parker as “the most radiant woman I ever met.”

“We were together almost nine months,” Hurst wrote. “It was the best nine months of our lives. We wanted to get married. We just celebrated her 24th birthday.”

Meanwhile, Ward was engaged to WDBJ morning producer Melissa Ott, who was celebrating her last day at work Wednesday before starting a new job in Charlotte, North Carolina. Ward had plans to move with his fiancee and get out of news, according to one of his co-workers, news anchor Jean Jadhon.
