Police in Twin Falls, Idaho, have identified Chad Williams, 24, as the gunman who opened fire at a newly opened In-N-Out Burger restaurant on Saturday, killing an employee and a customer before dying from what investigators say was a self-inflicted gunshot wound. The shooting has drawn national attention both for the tragedy itself and for the intervention of an off-duty state trooper and an armed civilian, who returned fire on the gunman and have been praised as heroes for potentially preventing further casualties.

Twin Falls Police Chief Matthew Hicks confirmed multiple fatalities and several injuries at the scene, with authorities continuing to investigate the circumstances and motive behind the attack. In-N-Out's president said the company's "heart is broken" over the loss of an employee and customers, as the restaurant chain and local community come to terms with the violence at the recently opened location.
