Authorities have identified the three men found fatally stabbed in the California apartment of Elliot Rodger, who police say fatally shot three others in a killing spree that ended with his suicide.
The Santa Barbara sheriff's office said Sunday that the victims were 20-year-old Cheng Yuan Hong and 19-year-old George Chen -- both from San Jose- - and 20-year-old Weihan Wang of Fremont.
The three UC Santa Barbara students were the first killed in Friday night's rampage. Hong and Chen are listed on the lease as Rodger's roommates. Investigators were trying to determine whether Wang was also a roommate or was visiting the night of the killings.
Rodger, 22, may have done so out of intense frustration at his rejection by women, which he detailed in multiple, shocking online videos.

Santa Barbara County Sheriff Bill Brown confirmed Saturday that Rodger was the man suspected of having shot and killed six people, shot and injured seven others, run over four more and left a 13th with unspecified injuries Friday night as he stalked the streets of Isla Vista, near Santa Barbara.
Rodger — the son of Peter Rodger, an assistant director on the blockbuster movie "The Hunger Games" — killed himself, apparently with a gunshot wound to the head, Brown said.
"It's very apparent the severe extent of how disturbed Mr. Rodger was," Brown said late Saturday afternoon. Earlier in the day, Brown had called the gunman "obviously ... a madman."
The Rodgers family is cooperating with investigators, said Alan Shifman, an attorney for the family, who said it was Rodger's own parents who alerted authorities to the distressing videos their son posted to YouTube — videos in which Rodger, a student at nearby Santa Barbara City College, complains that his college years have been torture because he could never get a date.
