First-person shooter: Armed with a gun and a camera, a social-media murderer goes viral

It almost looked like a first-person shooter video game: A handgun in a man’s grasp comes into view. A woman appears in the gunman’s sights. Shots are fired.

But this was no game. It was the chilling video by a killer of him stalking his prey - two television journalists live on-air for a station in Virginia that fired him for erratic behaviour in 2013.

A small audience will have witnessed the attack live on television. But internet users, even if only for a brief time, had a first-person view of his horrific crime after the killer fired off tweets while on the run and then posted his sickening video online.

“This seems like we’re turning a new page in the internet era,” Endpoint Technologies Associates analyst Roger Kay said.

“It’s definitely a new frontier. Except for ISIS, really nobody has done this.”
