The man suspected of killing six people in the Santa Barbara area on Friday night has been identified as Elliot Rodger, the son of an assistant director on The Hunger Games.

“The Rodger family offers our deepest compassion and sympathies to the families involved in this terrible tragedy,” the family said in a statement obtained by People. “We are experiencing the most inconceivable pain and our hearts go out to everyone involved.” Peter Rodger served as a second-unit director on the first installment of the popular film franchise.

According to authorities, the 22-year-old went on a rampage near the University of California, Santa Barbara, stabbing three men in his apartment before driving a BMW in a series of shootings. He fatally shot two female university students in front of a sorority and a third male student inside a deli. Thirteen people were injured, including two bicyclists hit by Rodger’s car, while others were hit by gunfire before the car crashed. Rodger — a high-functioning patient with Asperger syndrome, family lawyers tell ABC — was found dead with a gunshot to the head. Authorities believe the wound was was self-inflicted.

A student at Santa Barbara City College, Rodger’s parents had become concerned about him in recent weeks, reporting disturbing videos he posted to YouTube to police, according to the family’s lawyer. Officers made a “welfare call” on Rodger on April 30 but “determined he did not meet the criteria for an involuntary mental health hold,” Sheriff Bill Brown said in a news conference on Saturday.

Rodger’s final YouTube video, in which he promises “retribution” against women, was posted hours before the rampage. “I’ll take great pleasure in slaughtering all of you,” he says in the video, which was taken down by YouTube on Saturday due to violation of the site’s terms of services.

“I don’t know why you girls are so repulsed by me,” he says in the clip, describing his frustration at never experiencing intimacy with a women, according to The Associated Press. “I am polite. I am the ultimate gentleman. And yet, you girls never give me a chance. I don’t know why.”

His anger extended to men who dated the women he was unable to connect with, saying, “I deserve girls much more than all those slobs.” After his acts of violence, he expected everyone to “finally see that I am, in truth, the superior one, the true alpha male.”

Sheriff Brown told CNN on Sunday that investigators are wrapping up a few details in the case, but “for the most part, I think, we have a pretty clear picture of what happened.”
