Three victims of the murder rampage in Isla Vista were identified today, one of whom was a 19-year-old UC Santa Barbara student from Westlake Village.

Weiss graduated from Westlake High School in 2013 and played on the school's water polo team and was in her first year at UCSB, according to friends who spoke to news media.

Weiss' sorority sister, Katie Cooper, was also among those killed, Santa Barbara County Sheriff's Bill Brown said. A third victim was identified by the sheriff as Christopher Ross Michael-Martinez, 20, of San Luis Obispo.

Cooper, who was studying art history and archaeology at UCSB, graduated from high school in Chino Hills, according to news reports that cited her Facebook page.

Thirteen others were injured, eight who were wounded by gunfire and four who were struck by the gunman's vehicle. The shooter, identified as Elliot Rodger, 22 also died.

Three males were found stabbed to death in Rodger's apartment, victims of attacks that preceded the shooting spree, while Cooper and Weiss were gunned down outside the Alpha Phi sorority, said Santa Barbara County Sheriff's Bill Brown. Martinez was shot and killed in a delicatessen, the sheriff said.

"You don't think it will happen to your child until it does," Richard Martinez, speaking to media outside the Santa Barbara County Sheriff's Department headquarters, said of his son. "Chris was a really great kid. Ask anyone who knew him."

He shared a photo of his son, a bat on his shoulder and clad in a Little League baseball uniform, who he said was an English major at UCSB and dreamed of one day being an attorney.

"His death has left our family lost and broken," Richard Martinez said.

"They talk about gun rights," he continued. "What about Chris' right to live? When will this insanity stop? When will enough people say, 'Stop this madness.' We don't have to live like this. Too many have died. We should say to ourselves: Not one more."

Rodger had posted a series of videos on YouTube detailing how lonely and unloved he was and how he would take revenge.

He was found dead with an apparent gunshot wound to the head inside a black BMW from which he fired shots, the sheriff said. Deputies found three handguns in his car and hundreds of rounds of ammunition in magazines, he said.

One of the guns was bought in Burbank and all were purchased legally by the suspect, Brown said.

Rodger's father, Peter Rodger, is credited as an assistant director on the "The Hunger Games" films. He also directed shows for HBO and other TV networks.
