Authorities have identified Chad Williams, 24, as the sole gunman responsible for a shooting at an In-N-Out Burger in Twin Falls, Idaho, on Saturday afternoon. The incident left at least three people dead and seven others wounded, officials said Sunday.

The shooting occurred shortly after 2:30 p.m. inside the busy restaurant, prompting panicked customers to seek cover both inside the establishment and in the parking lot. Police received multiple calls reporting gunfire and screaming as chaos unfolded during what had been a typical Saturday afternoon for shoppers and diners at the local shopping center.

Twin Falls Police Chief Matthew Hicks described the actions of an off-duty state trooper and a private citizen who returned fire as “heroic,” crediting them with helping to drive the suspect away from the scene and possibly preventing additional casualties. Williams died from a self-inflicted gunshot wound before law enforcement arrived, Chief Hicks confirmed. The motive behind the shooting remains under investigation.

The identities of the victims have not been officially released, as some family members have not yet been notified. However, social media posts and local sources have provided some information. Among those killed was an In-N-Out employee, described by the company’s president, Lyndi Snyder, as a valued team member who was assisting customers at the time of the attack.

Two other victims have been identified publicly. Christopher Claunch, who worked at the Renaissance Ranch Recovery Center in Rupert, Idaho, died from injuries sustained in the shooting. Claunch, originally from California, had found sobriety after years of struggling with alcoholism and dedicated himself to helping others after completing a recovery program. He was remembered by family and friends as a devoted partner, lover of the outdoors, and a caring individual who remained positive despite past hardships.

Another injured individual, 62-year-old taxi driver Terry Dudley, was shot while charging his electric vehicle nearby, according to a fundraising page established by his employer. Dudley, a widower with four children, was described as loyal, compassionate, and deeply valued by his community and co-workers.

Among the seven wounded, two remained in critical condition Sunday, three were stable, and two had been treated and released from local hospitals. Authorities are continuing to interview hundreds of witnesses to reconstruct the timeline of events.

In a related development, shortly after law enforcement arrived at the scene, officers were involved in a separate shooting during the search for Williams. No injuries were reported in that incident, which is now under review by the Jerome Police Department.

The investigation into the shooting is being led by the Twin Falls Police Department in coordination with the Federal Bureau of Investigation. Chief Hicks emphasized that the Williams family has been notified and is cooperating with authorities as they work to clarify the circumstances and possible motives behind the attack.
