Twin Falls: Police release new details in fatal In-N-Out shooting; investigation remains active

TWIN FALLS, Idaho (KIFI) — Twin Falls Police released new information Friday about the August 1 mass shooting at the city's In-N-Out Burger, saying investigators still have no known motive while confirming the suspect acted alone. The investigation remains active with assistance from the FBI, Idaho State Police and the Twin Falls County Sheriff's Office.

Police said 24-year-old Chad Williams opened fire at the restaurant, killing three people and injuring seven others before dying from a self-inflicted gunshot wound after being confronted by an off-duty law enforcement officer and an armed citizen.

During Friday's news conference, Chief Matthew Hicks said detectives continue reviewing surveillance video, processing evidence and conducting interviews with witnesses. Officials emphasized there is no evidence anyone else was involved, and investigators believe Williams acted alone. However, authorities say the case is far from over as they continue working to determine what led to the attack.

Police said 10 people were struck by gunfire, including the suspect. Of the three victims killed, two died inside the restaurant while one died in the parking lot. Officials also confirmed one of those killed was an In-N-Out employee.

The three people killed were identified as Ashley Garibay, 23, of Stockton, California, Dale Schultz, 66, of Salt Lake City, and Christopher Claunch, 59, of Hagerman. Some victims' identities have not yet been released publicly as authorities continue coordinating with their families.

Investigators also recognized the actions of two men who engaged the shooter.

Police identified Jordan Salinas, an off-duty law enforcement officer, as one of the people who returned fire during the incident. They also recognized retired Twin Falls police officer AJ Scott (Austyn James Scott), who confronted the gunman. Authorities credited their actions with helping prevent additional casualties.

Officials outlined the scale of the emergency response, saying the first officer arrived within about three minutes of the initial 911 call. It took investigators approximately 90 minutes to confirm there was only one suspect.

Dispatchers received 85 emergency calls within the first 10 minutes of the shooting, while more than 150 first responders from approximately 50 agencies responded to the scene.

Support services remain available for victims and their families. Twin Falls officials said assistance is being provided through the American Red Cross, while the city is partnering with NOVA to provide counseling and other recovery resources.

Authorities stressed Friday that the investigation remains active and ongoing. Detectives with the Twin Falls Police Department continue working alongside the FBI, Idaho State Police, and the Twin Falls County Sheriff's Office as they analyze evidence and continue interviewing witnesses. Police are still asking anyone with photos, videos, or additional information that has not yet been shared with investigators to come forward.
