A mass shooting outside an In-N-Out Burger restaurant in Twin Falls, Idaho, on August 1, 2026, has left three people dead and seven others injured. Police have identified the suspected gunman as 24-year-old Chad Williams, who died from a self-inflicted gunshot wound after being confronted by an armed off-duty state trooper and a private citizen. Here is a complete breakdown of the incident, the victims, and the investigation as it currently stands.
How the Shooting Unfolded
The attack began around 2:29 p.m. on Saturday, August 1, 2026, when multiple 911 calls reported gunfire at an In-N-Out Burger on Blue Lakes Boulevard North in Twin Falls, Idaho. Dispatchers reportedly heard screaming and gunshots in the background of the calls. The restaurant sits inside an outdoor shopping complex that also includes several major retailers and a movie theater, an area that was likely crowded at the time of the shooting.
A witness told reporters that as she waited in the drive-thru line, she saw people running across the road and employees fleeing the restaurant. She initially believed there may have been a fire before someone directing traffic told her a shooter was active nearby.
Who Is the Suspected Shooter, Chad Williams
Twin Falls Police Chief Matthew Hicks identified the suspected gunman as 24-year-old Chad Williams during a news conference on Sunday, August 2, 2026. According to police, Williams died from an apparent self-inflicted gunshot wound after an armed off-duty Idaho state trooper and a private citizen returned fire, which investigators believe drove him away from the scene and may have prevented further casualties.
Police say Williams appeared to act alone, and investigators have not yet released a confirmed motive. Officials have also pushed back on inaccurate social media posts that misidentified other individuals as the shooter, urging the public to avoid spreading unverified information. Williams’ family is reportedly cooperating with the investigation.
Victims of the In-N-Out Shooting
Three people were killed in the shooting, not including the suspected gunman. In-N-Out Burger president Lynsi Snyder confirmed that one of the three victims was a company employee who was working at the time of the attack. Snyder released a statement expressing grief over the loss, saying the employee was taken care of the restaurant’s customers when her life was taken.
Seven additional people were injured, with two reported to be in critical condition, three in stable condition, and two treated and released from the hospital, according to police. One of the wounded was reportedly a taxi driver who was shot in the back and neck area while charging his vehicle nearby. Authorities have not released the names of the deceased victims out of respect for their families, though that may change as notifications are completed.
The Bystanders Who May Have Stopped a Bigger Tragedy
Police credited an armed private citizen and an off-duty Idaho state trooper, both of whom happened to be near the restaurant, with returning fire at the gunman. A witness who was stopped at a nearby traffic light described watching the shooter move through the drive-thru appearing panicked and disoriented as gunfire was exchanged. Chief Hicks called their actions heroic, saying they likely helped push the suspect away from the area and prevented additional casualties.
Investigation and Official Response
The FBI confirmed that its agents were on the scene assisting local and state authorities. Idaho Governor Brad Little asked the public for prayers as law enforcement responded to what was initially described as an active shooter situation. Chief Hicks said investigators expect to interview hundreds of potential witnesses as they work to piece together a timeline and determine Williams’ motive, an effort that may take time given the scale of the incident.
In-N-Out Burger, headquartered in California, is known for operating a relatively small footprint of locations concentrated mostly in the western United States, and the Twin Falls store had reportedly opened recently before the shooting occurred.
What Happens Next
As of this writing, the investigation remains active, and authorities have not disclosed a confirmed motive behind the shooting. Details about the victims, potential charges (had the suspect survived), and any additional findings from witness interviews may continue to develop in the coming days. Readers should expect official updates directly from the Twin Falls Police Department as the case progresses.
