A 22-year-old man went on a shooting and stabbing rampage on Friday night near the University of California, Santa Barbara (UCSB) campus in Isla Vista, killing six students and injuring 13 more. The confirmed suspect claimed it was his "day of retribution" for a lifetime of rejection by women.
The suspect frequently posted misogynistic and racist comments on "Men's Rights Activist" online forums and posted several videos online detailing his hatred of women and humanity in general and his feelings of alienation. In a YouTube video posted before the attack, the suspect details his plan to "punish" women through a killing spree. He had also written a 140-page manifesto about his life and his thoughts on women, calling women "a plague" and claiming they should be kept in concentration camps.
The suspect's mother and therapist had previously become concerned by the suspect's increasingly violent online posts and videos. According to a lawyer for the family, the therapist reported concerns to a local mental health service which referred the report to police. Officers conducted a welfare visit a month before the attack, visiting the suspect in his home, but did not see the need to investigate further.
The course of events Friday night left nine crime scenes. He first stabbed to death his three roommates in his apartment, then tried to enter the Alpha Phi sorority house on the UCSB campus. The sorority members did not open the door when he repeatedly knocked. He then drove around Isla Vista, shot a man in a deli, then opened fire on pedestrians, killing two women. His reckless driving injured more as he attempted to flee from police. Eventually, he got in a shoot-out with the police before killing himself with a gunshot wound to the head.
