A Saturday afternoon that should have been ordinary turned into one of the worst days Twin Falls, Idaho has ever seen. On August 1, 2026, a gunman opened fire at a newly opened In-N-Out Burger restaurant on Blue Lakes Boulevard — killing three people, injuring seven more, and sending hundreds of witnesses scrambling for safety before the threat was brought to an end.
The suspected shooter, identified as 24-year-old Chad Williams, died from a self-inflicted gunshot wound. Three people are dead. Two remain in critical condition as of Sunday. And a community that had spent the week celebrating the arrival of a beloved new restaurant is now grappling with grief, fear, and the question that never seems to stop being asked in this country: why?
What Happened
At 2:29 p.m. on Saturday, multiple 911 calls flooded into Twin Falls emergency dispatch reporting shots fired at the In-N-Out Burger on Blue Lakes Boulevard, located in one of the city’s busiest commercial corridors — a stretch of the north side filled with national retailers, hotels, a movie theater complex, and restaurants that serve both local residents and travelers passing through.
What officers arrived to find was, in the words of Twin Falls Police Chief Matthew Hicks, “one of the most chaotic instances a law enforcement officer can face in their career.” There were potentially hundreds of people in the area at the time of the shooting — patrons inside the restaurant, customers in the drive-thru lane, people in the adjacent parking lot charging their electric vehicles, shoppers moving between nearby stores. Witnesses described chaos: screaming, people diving under tables, others barricading themselves in the restaurant’s bathrooms while gunfire rang out outside.
Eyewitness Lane Koehn, 34, was sitting at a red light just outside the restaurant when the shooting began. He told NBC News he saw a person emerge from the drive-thru line carrying what appeared to be an AR-style rifle and begin firing. Bullets struck the car directly in front of him. Koehn watched as the gunman moved erratically through the lot, apparently uncertain where to go next — and said what changed the dynamic was a man in the drive-thru line with a handgun who began shooting back.
“I could tell he was panicked,” Koehn said of the shooter. “He was looking around, kind of erratic. Somebody in the drive-thru line with a handgun was shooting at him.” Koehn believes that armed response kept the gunman from firing at more people.
Two People Stepped Up — And Police Say They Saved Lives
The armed civilian in the drive-thru has since been identified as Jordan Salinas, who was carrying a suppressed FN Five-Seven handgun. An off-duty Idaho State Police trooper who was present at the scene also drew his weapon and returned fire.
Together, both individuals engaged Williams directly. Police Chief Hicks confirmed at a Sunday press conference that their actions are credited with driving Williams away from the scene before additional casualties occurred.
“We believe these actions drove the suspect from the scene and prevented further casualties,” Hicks said. Twin Falls County Sheriff Jack Johnson was more direct: “I want to extend my deepest thanks to the off-duty trooper and the good citizen that engaged the shooter. These people are true heroes in our community, and their actions diverted the shooter and no doubt saved many lives.”
Williams was later found dead from a self-inflicted gunshot wound in an area near the restaurant. Police confirmed he acted alone.
The Victims
Three people were killed in the shooting. The identities of the deceased had not been officially released as of Sunday afternoon, pending notification of next of kin.
What we do know is that one of the people killed was an In-N-Out employee. In-N-Out Burger owner and President Lynsi Snyder confirmed the loss in a statement posted to social media, writing: “In-N-Out will be mourning with the families and praying for them as they tread through a very painful season.”
Of the seven people injured, two were treated and released from St. Luke’s Magic Valley Medical Center. Three others remained hospitalized in stable condition. Two more were listed in critical condition as of Sunday.
A Restaurant That Had Only Been Open One Week
The timing adds another layer of tragedy to an already devastating story. The Twin Falls In-N-Out Burger had opened its doors on July 24 — just one week before the shooting. It was part of the chain’s recent expansion into Idaho, and its opening had been a celebrated local event, the kind of thing that brings a community together.
A week later, that same restaurant became a crime scene.
The Suspect: What We Know About Chad Williams
Police identified the gunman as Chad Williams, 24, of Twin Falls. Beyond his name and age, little has been officially confirmed about him. A motive remains under investigation, and Chief Hicks has urged the public strongly to avoid spreading misinformation — noting that at least one other person sharing the same name, an active duty service member, had already been targeted with online harassment and false accusations in the hours following the shooting.
“This information is absolutely false,” Hicks said, referring to the misidentification circulating on social media, and asked the public to allow investigators to do their work.
Williams’ family has been notified and is cooperating with authorities. “Their hearts are also broken at this time,” Hicks said.
The FBI’s Salt Lake City field office has set up a digital media tipline asking anyone with photos, video, or other digital evidence from the scene to come forward. Hundreds of witnesses are expected to be interviewed as the investigation continues.
A Community in Shock
Twin Falls is a city of roughly 56,000 people located about 130 miles southeast of Boise. It’s a regional hub for southern Idaho — the kind of place where a busy Saturday afternoon at a commercial strip is a normal, unremarkable part of life. Until August 1, 2026, it wasn’t a city most people outside Idaho would have had a reason to think about.
Idaho Governor Brad Little issued a statement on social media asking for prayers “as law enforcement and first responders respond to an active shooter situation near In-N-Out.” The governor offered no further public comments as of Sunday.
The area around the In-N-Out and the Twin Falls Visitor Center remained closed throughout the weekend as investigators processed the scene.
The Question That Never Goes Away
There is a version of this story that becomes routine — not because it isn’t heartbreaking, but because it keeps happening. A public place. A Saturday afternoon. People going about their day. Gunfire. Death. A community left to mourn while the country debates what to do next, and often does nothing.
What makes this particular incident stand out from the immediate news cycle is the role the armed civilian and the off-duty trooper played in limiting the death toll. That story will be told and retold in the weeks ahead — and it should be. Their actions that day were genuinely heroic.
But three people are still dead. Two more are in critical condition. And a motive hasn’t been identified yet, which means answers — the kind that might actually help prevent the next one — are still a long way off.
Our thoughts are with the victims, their families, the In-N-Out employees who lived through this, the first responders, and the entire Twin Falls community.
