The alleged gunman in Friday night’s shooting at the University of California Santa Barbara campus also stabbed his three roommates in their home before beginning his rampage, Santa Barbara County Sheriff Bill Brown told reporters Saturday night.

“It was a pretty horrific crime scene’’ at the apartment, Santa Barbara County Sheriff Bill Brown told reporters.

From there, 22-year-old Elliot Rodger allegedly drove to a sorority on the campus, where he shot three female passersby, two of whom would later die from their injuries. The suspect then allegedly shot a third victim to death outside of a nearby deli and ran over pedestrians and cyclists as he fled the scene in a black BMW.


Rodger engaged police in a shootout before he died from what authorities said appeared to be a self-inflicted gunshot wound.

Rodger was reportedly under psychiatric care and “diagnosed with ‘highly functional Asperger’s syndrome’ as a child, the BBC reported.

An unnamed source close to the family told the LA Timesone of Rodger’s parents contacted police last month over concerns about videos he posted online that threatened violence. Washington Post reporter Phillip Bump said police told him they investigated Rodger but concluded he was not dangerous.

Rodger apparently filmed himself lamenting his social status and the alleged mistreatment from females he said pushed him to the massacre and posted it online:

In one portion of the video, entitled “Retribution,’’ Rodger said “if i can’t have you, girls, I will destroy you.’’ He specifically referenced a group of sorority girls he planned to target.
