AFP reports that the former TV reporter who shot two journalists dead during a live broadcast in Virginia before killing himself warned he had been a "human powder keg... just waiting to go BOOM."
The gunman- Vester Lee Flanagan, 41, also known as Bryce Williams, posted chilling footage of Wednesday's murder online.
Reporter Alison Parker, 24, and cameraman Adam Ward, 27, were fatally shot at close range while conducting an on-air interview for WDBJ, a CBS television affiliate in Roanoke, about 240 miles (385 kilometers) southwest of Washington. It was unclear whether the shooter even knew Parker before the attack.
