The suspect in a fatal shooting at an In-N-Out Burger in Idaho died of a self-inflicted gunshot wound, police said Sunday, crediting an off-duty officer and a citizen with firing shots that diverted him. Investigators are confident that the gunman, identified as 24-year-old Chad Williams, acted alone during the shooting Saturday in Twin Falls, Police Chief Matthew Hicks said at a news conference. In all, three people died and seven others were injured at the recently opened fast-food restaurant in the southern Idaho city of about 56,000 people, the AP reports. Authorities said Sunday that two of the injured were treated at a hospital and released, three were listed as stable, and two were in critical condition.

Hicks said an off-duty state trooper and an armed citizen—whose identities weren't immediately disclosed—both fired back and diverted the gunman from the restaurant. "We believe their actions helped drive the suspect away from the scene, preventing further casualties," the chief said. Hicks said detectives are working to determine Williams' motives, and said the suspect's family was cooperating fully with law enforcement. He also warned of misinformation spreading online identifying a different man as the shooter, saying the man had "no involvement in this incident whatsoever."

One of those killed was an employee, the fast-food chain's owner said. "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," In-N-Out owner Lynsi Snyder said in a statement released early Sunday on social media. "In-N-Out will be mourning with the families and praying for them as they tread through a very painful season." The FBI on Sunday encouraged the public to submit images and videos related to the shooting Saturday in Twin Falls that left seven other people wounded, some critically. The In-N-Out had opened just about a week earlier, on July 24, as part of the California-based company's recent expansion to Idaho.

Lane Koehn, 34, said he was at a stoplight near the In-N-Out when he saw a person with an AR-style rifle emerge from the drive-thru, apparently walking toward his car. Then "somebody in the drive-thru line with a handgun was shooting at him," Koehn tells NBC News. Koehn then saw someone in an In-N-Out uniform drag a person, also wearing a uniform, bleeding from a gunshot wound to her chest across the parking lot. The employee, Koehn, and the man with the pistol who shot at the suspect all stayed until paramedics arrived for the injured worker. Koehn said the shooter fired at least three or four rounds and it was not clear whether or not anyone in particular was targeted. Officials were still trying to notify relatives of victims and so were not yet releasing the names, ages or other details about the people hurt in the shooting.
