Three killed, seven injured in Twin Falls In-N-Out shooting; suspect identified as Chad Williams

TWIN FALLS, Idaho - A mass shooting at the newly opened In-N-Out Burger on Blue Lakes Boulevard left three people dead and seven others injured on Saturday afternoon, August 1, 2026, authorities said. The suspect, identified as 24-year-old Chad Williams, died of a self-inflicted gunshot wound.

The Twin Falls City Communications Center began receiving 911 calls reporting shots fired at approximately 2:29 p.m. local time. Multiple agencies, including Twin Falls police, Idaho State Police, neighboring departments, and federal partners, responded to the busy commercial area near the I.B. Perrine Bridge. Roads were temporarily closed and nearby businesses locked down before the threat was declared over and restrictions lifted.

Twin Falls Police Chief Matthew Hicks confirmed the casualty figures during a Sunday news conference: three victims deceased, seven injured (two treated and released, three in stable condition, and two remaining in critical condition as of the latest updates). The numbers are preliminary. Victim identities have not been publicly released by police out of respect for families still being notified.

In-N-Out Burger President Lynsi Snyder confirmed that one of the company's associates, a female employee, was among those killed. "We lost one of our beautiful Associates tonight. She was taking care of our most important asset - our Customers," Snyder said in a statement. She added that the gunman "ended his life shortly after" the attack. One of the injured has been identified by his employer as Terry Dudley, a North Star Taxi driver who was shot while charging his Tesla and is expected to face a lengthy recovery.

Williams, the lone shooter, opened fire with a long or AR-style rifle in and around the restaurant, which had opened on July 24 as part of In-N-Out's expansion into Idaho. Investigators said he acted alone. A motive has not been determined. Police have warned the public against sharing unverified information circulating on social media, including false identifications of the shooter.

An off-duty Idaho State Police trooper and an armed civilian returned fire toward the suspect. Officials said their actions helped drive Williams away from the immediate scene and prevented further casualties. Twin Falls County Sheriff Jack Johnson called the pair "true heroes in our community" who "diverted the shooter and without a doubt saved many lives." Multiple reports and social media videos have identified the civilian as 35-year-old Jordan Salinas of Kimberly, Idaho, who has spoken about drawing his handgun and engaging the shooter.

The FBI is assisting the investigation and has established a digital media tip line at fbi.gov/twinfallsshooting for anyone with photos, videos, dashcam footage, or other relevant material. Crisis counseling resources have been made available to the community.

The investigation remains active. Authorities continue to review evidence, conduct interviews, and notify next of kin.
