An investigation continues in Twin Falls, Idaho, following a shooting at an In-N-Out Burger that left three people dead and seven injured. Authorities have identified the shooter as 24-year-old Chad Williams, who died from a self-inflicted gunshot wound at the scene. Police confirmed Williams acted alone in the attack.
Local law enforcement credited two individuals for preventing further casualties during the incident. An off-duty Idaho state trooper and an armed citizen, identified as Jordan Salinas, returned fire when the shooter opened fire in the restaurant parking lot. Their immediate response forced the suspect to divert his attention, allowing many customers and employees to flee to safety.
Salinas, a 35-year-old healthcare worker from Kimberly, Idaho, carried a concealed firearm at the time of the shooting. He described his decision to engage the gunman as a duty he felt compelled to perform. Salinas noted that the gunman was surprised by the armed resistance, stating that the shooter did not like it when bullets started firing back at him.
Twin Falls Police Chief Matthew Hicks praised the actions of the trooper and the civilian, noting that they undoubtedly saved many lives. While the investigation into the shooter's movements and background remains ongoing, officials are still seeking a motive for the attack. The family of the suspect is cooperating with police as detectives review evidence and conduct interviews.
Two of the seven wounded victims remain in critical condition, while others are listed as stable or have been released. In-N-Out Burger company leadership confirmed that one of their employees was among those killed while working. The company is currently providing support to the affected families and staff during this period of mourning. The FBI is assisting local authorities by gathering footage and witness accounts from the scene.
