San Bernardino Shooter’s Neighbor Often 'Intoxicated,' Would Ask People for Adderall

In a 2014 video, Enrique Marquez appears intoxicated and calls himself “G-Man."

— -- The man accused of helping San Bernardino shooter Syed Farook acquire his guns loves punk rock and once called himself “G-Man,” according to new video obtained by ABC News.

In the video, Marquez appears sitting on a couch at a party in late 2014. The camera closes in on his face as he asks, “Hello, how’s it going?”

“My name’s G-man,” Marquez says to the camera.

Michael G. Stone, an acquaintance of Marquez who took the video, told ABC News Marquez was a fan of a punk rock band called BDSM, and would often show up at their shows and parties.

“We had huge six to eight dozen people parties. He would just show up at almost all of them,” Stone said. “He was intoxicated… he would always ask people for Adderall”

Today, Marquez pleaded not guilty to all five charges against him at his arraignment hearing in court today. A trial date has been set for Feb. 23.
