TWIN FALLS, Idaho (VINnews) — TWIN FALLS, Idaho (AP) — A civilian whose actions were captured on video during Saturday’s deadly shooting outside an Idaho In-N-Out Burger said in an ABC News interview that the gunman’s confidence “immediately crumbled” after he returned fire, a confrontation police say likely prevented additional casualties.

Jordan Salinas, 35, said he was driving with his girlfriend near the Twin Falls restaurant when they noticed people running from the area. As they approached, Salinas said he saw a man later identified as 24-year-old Chad Williams standing with a rifle pointed toward passing vehicles.

“I saw the individual with his rifle pointed at the vehicles,” Salinas told ABC News. “He seemed unusually comfortable aiming that rifle at those cars.”

Video recorded by a bystander and widely shared online shows Salinas taking cover behind a roadside sign before stepping out and firing his handgun toward the gunman. Authorities have not said whether any of Salinas’ shots struck Williams.

Salinas said he immediately instructed his girlfriend to call 911 while he assessed the unfolding attack. Carrying a legally owned FN Five-seveN semiautomatic pistol, he moved behind cover before returning fire.

“As soon as some rounds started coming at him, everything changed immediately,” Salinas said. “All that bravado he had immediately crumbled.”

According to investigators, Williams had opened fire outside the restaurant, killing two people and wounding seven others. Authorities said he later fled toward a nearby parking lot, where he died from a self-inflicted gunshot wound.

Twin Falls Police Chief Shannon Hicks said Sunday that the actions of Salinas and an off-duty law enforcement officer who also confronted the gunman disrupted the attack and likely saved lives.

“We believe these actions drove the suspect from the scene and prevented further casualties,” Hicks said during a news conference.

Police have not determined whether Williams was struck by gunfire from either Salinas or the off-duty officer, but investigators said the exchange forced him away from the crowded restaurant area.

The two people killed were identified as Christopher Claunch, 59, and Ashley Garibay, 23, an In-N-Out employee. Five of the seven people injured remained hospitalized Sunday, including two in critical condition, authorities said.

Salinas, a healthcare worker who is also the full-time caregiver for his disabled brother, said the shooting marked the first time he had ever aimed his firearm at another person.

He told ABC News he had prepared for such a scenario after witnessing the aftermath of the 2021 shooting at Boise Towne Square mall, where two people were killed and several others were wounded.

“I hoped I would never have to use that training,” Salinas said.

Authorities said Williams had previously attended the College of Southern Idaho but did not graduate. Investigators are reviewing his background and online activity as they work to determine a motive for the attack.

The shooting has drawn national attention not only because of the deadly attack but also because of the actions of Salinas and the off-duty officer, whose intervention came before responding officers arrived.

Law enforcement agencies generally advise people confronted with an active shooter to flee if possible, hide if escape is not an option and fight only as a last resort. Police in Twin Falls said the actions of Salinas and the off-duty officer helped interrupt the attack under extraordinary circumstances.

The investigation remains ongoing.
