Three people were killed and another seven were injured when a gunman opened fire outside an In-N-Out Burger restaurant in Twin Falls, Idaho, on Saturday, authorities told ABC News on Sunday.
The suspected shooter, whom officials identified as 24-year-old Chad Williams, died from an apparent self-inflicted gunshot wound after being confronted by an armed off-duty Idaho state trooper and a private citizen, Twin Falls Police Chief Matthew Hicks said at a news conference on Sunday.
“We believe these actions drove the suspect from the scene and prevented further casualties,” Hicks said of the off-duty trooper and private citizen’s actions.
Five of the seven injured victims remained hospitalized on Sunday afternoon, including two in critical condition, according to Hicks.
A motive for the shooting remains under investigation. Hicks said the suspected gunman’s family members are cooperating with the investigation.
“Their hearts are also broken at this time,” Hicks said of Williams’ relatives.
Hicks said investigators so far believe that Williams acted alone.
Lynsi Snyder, In-N-Out’s president, said in a statement posted on social media that an employee was among those shot and killed.
“In-N-Out will be mourning with the families and praying for them as they tread through a very painful season,” she said.
