Did the station have any prior knowledge and able to stop this from happening? Only time will tell as they continue their investigation.
According to Yahoo:
Someone using the name of WDBJ TV news shooter Bryce Williams sent a 23-page fax to ABC News the night before the incident, which the network turned over to authorities.
“Sometime between Tuesday night and this morning, ABC News received a fax from someone claiming to be Bryce Williams,” the network reported. “It is a lengthy document: 23 pages. ABC News has turned it over to authorities.”
It’s not known what the fax contained or whether authorities have authenticated that it was in fact sent by Williams.
Williams is the name the shooter used professionally; his real name is Vester Flanagan. Flanagan filmed himself shooting reporter Alison Parker, 24, and cameraman Adam Ward, 27.
He posted videos and rants on Twitter and Facebook airing his grievances with the journalists. His tweets included:
“Alison made racial comments.”
“EEOC report filed. They hired her after that?”
“Adam went to HR on me after working with me one time!!!”
“I filmed the shooting. See Facebook.”
