TWIN FALLS, ID — A 59-year-old man from Santa Clarita was among those killed in Saturday's mass shooting at an Idaho In-N-Out Burger that left three dead and seven wounded, according to reports.

Among the deceased is Christopher Claunch, a longtime Idaho resident who grew up in Canyon Country, his sister, Kimberly Castaneda, told KTLA.

The attack at a new In-N-Out in Twin Falls, Idaho, ended when the gunman, identified by police as 24-year-old Chad Williams, shot and killed himself. On Monday, police were still trying to determine why Williams carried out the attack, which happened early in the afternoon in a busy shopping plaza in the southern Idaho city.

Garren Taylor, one of Claunch's friends, said that two years ago, Claunch completed a rehab program for alcohol abuse at Renaissance Ranch Recovery Center in Rupert, Idaho, and was immediately hired there. Taylor said Claunch, known to those close to him as "Toph," had since then dedicated his life to helping others get sober.

"He helped hundreds of people," Taylor recalled Monday. "He was just a gift to anyone he came in contact with. It wasn't about the paycheck, his attitude was: 'I get to help someone today.'"

His sister told KTLA that Claunch was the life of the party and an excellent cook.

The other victims include 23-year-old In-N-Out worker Ashley Garibay of Stockton, who was also killed, according to KCRA, as well as a driver charging his electric taxi and a former law enforcement officer who tried to intervene, both of whom were wounded, according to friends and relatives of the two men. Of those injured, two were treated at a hospital and released, three were listed as stable, and two others were in critical condition, police said Sunday.

Details Of The Shooting

During the attack, an off-duty state trooper and a civilian fired on Williams and diverted him from the restaurant, Police Chief Matthew Hicks said.

Detectives are confident that Williams acted alone, Hicks said Sunday, noting that Williams' family is cooperating fully with the investigation.

Many details about Williams' life were still unknown Monday, but an initial search of court records in Idaho and Arizona, where he used to live, didn't show any criminal cases matching his name and birth date.

Elijah Moseley, who lived across the hall from Williams in a College of Southern Idaho dorm a few years ago, described him as "an introvert" and "a pretty chill guy."

"I was never scared or weirded out by him," he said.
