Just moments after he shot two innocent journalists to death on live TV and before shooting himself, Bryce Williams said, in a message, that "I've been a human powder keg for a while....just waiting to go BOOM."
The gunman wrote the words in a chilling fax sent to ABC News, according to a statement released by network. The Virginia shooter sent the manifesto after killing WDBJ-TV journalists Alison Parker and Adam Ward, resulting in a manhunt that concluded when officers closed in.
The manifesto cited the Charleston shooting as the trigger point for the plotting of the savage attack.
While the shooter, who formerly worked as a reporter for the Roanoke station, is now dead, the investigation is far from over.
The manifesto, as well as the gunman's other efforts to reach out to journalists and his social media posts just after the attack will be key pieces of information investigators will use to piece together what happened and why.
Franklin County Sheriff Bill Overton said authorities are looking at his past employment at WDBJ as well other evidence to attempt to determine a motive for the killings.
"Many of you have gotten a lot of the correspondence, emails that had been sent out. It's obvious that ... this gentleman was disturbed in some way of the way things had transpired," and that "at some point in his life, things spiraled out of control," Overton stated.
