Investigators are seeking a motive after a 24-year-old man opened fire at an In-N-Out Burger in Twin Falls, Idaho, killing three people and wounding seven others before dying of a self-inflicted gunshot wound. Police Chief Matthew Hicks said Chad Williams acted alone, and an off-duty trooper and a civilian fired shots that diverted him. An employee was among the dead.
