The man featured in a disturbing YouTube video who went on a killing spree murdering at least six and wounding several more was identified Saturday evening by authorities as Elliot Rodger, 22.
Calling him "severely mentally disturbed," Santa Barbara County Sheriff Bill Brown said the 22-year-old stabbed to death three individuals at his residence "prior to [the] shooting rampage" that took place near the University of California, Santa Barbara campus Friday night.
The entire incident left at least seven dead, including Rodger, and was described by authorities as "obviously the work of a mad man." Several others were wounded and seven individuals remain hospitalized. Three of the victims have been identified.
