Idaho In-N-Out Shooting Leaves 3 Dead, 7 Injured as FBI Joins Investigation

Three people were killed and seven others were injured, several of them critically, after a gunman opened fire at a newly opened In-N-Out Burger restaurant in Twin Falls, Idaho, on Saturday afternoon, in one of the deadliest mass shootings in the state this year.

Twin Falls city spokesman Josh Palmer said police responded to reports of an active shooter at around 2.30 pm local time at the busy shopping plaza. The suspected gunman was later found dead near the restaurant, but authorities have not yet confirmed whether the suspect is included in the official death toll of three. The injured were taken to St. Luke's Magic Valley Medical Center for treatment.

Police have not released the identities of the victims or the suspect as officials continue informing family members. Twin Falls Police Chief Matthew Hicks said investigators are working to establish the shooter's identity and motive and expect to interview hundreds of witnesses because of the large number of people present at the shopping complex.

Witnesses said the attacker was carrying an AR style rifle. Some reported that an armed bystander returned fire in an apparent attempt to stop the gunman, though police have not officially confirmed that account. Authorities described the scene as chaotic, with customers and employees fleeing for safety.

The FBI is assisting the Twin Falls Police Department, which continues to lead the investigation. Officials said there is no ongoing threat to the public, and a temporary shelter in place order has been lifted.

The Twin Falls outlet had opened only about a week earlier. Idaho Governor Brad Little expressed condolences to the victims' families, while In-N-Out President Lynsi Snyder said the company was heartbroken, confirmed that one employee was among those killed, and pledged support for affected workers and families. The motive for the attack remains unknown.
