A shooting at a newly opened In-N-Out Burger restaurant in Twin Falls, Idaho, on Saturday afternoon, August 1, left three people dead and seven others wounded, local authorities said [1, 2, 3]. The gunfire started between 2:00 and 2:30 p.m. in a busy shopping plaza where the restaurant is located [1, 2, 3].

Among the three fatalities was one In-N-Out employee, while the other two victims were customers [2, 3, 4]. Seven others were injured, with reports indicating five remained in stable or critical condition and two were treated and released [2, 3, 5]. Twin Falls Police Chief Matthew Hicks described the scene as "very chaotic" but said, "We believe the threat to the community is over" [1, 2].

The suspected shooter was identified as 24-year-old Chad Williams. Authorities found him dead near the scene from a self-inflicted gunshot wound later that evening [2, 3, 6, 7]. Police said Williams acted alone in the shooting [2, 7]. An off-duty state trooper and an armed bystander fired at Williams, forcing him to move away from the restaurant and potentially preventing further casualties, Chief Hicks said: "We believe their actions helped drive the suspect away from the scene, preventing further casualties" [2].

Witness Lane Koehn said he saw a person with an AR-style rifle emerge from the drive-through and another individual with a pistol firing at the shooter [1, 8, 9]. An In-N-Out employee helped drag a wounded woman, who had a gunshot wound to her chest, across the parking lot until paramedics arrived [1, 8, 9]. Koehn said of the victim, "She was pretty bad off, but I don’t know. I hope she made it" [1].

Twin Falls, a city of approximately 56,000 in southern Idaho, was urged by authorities to keep away from the area while emergency crews worked [1, 10]. Police continue investigating the motive behind the attack and are notifying victims' families [1, 3, 6].

In-N-Out owner Lynsi Snyder expressed heartbreak over the loss and pledged to support the families of the victims: "My heart is broken, my chest is heavy, my eyes burn from the tears I’ve shed. We lost one of our beautiful Associates tonight" [2, 5].
