A shooting at an In-N-Out Burger restaurant in Twin Falls, Idaho, on Saturday was halted after a civilian intervened, authorities and witnesses said. The incident left two people dead before the gunman was confronted by a bystander armed with a pistol.

Jordan Salinas, 35, recounted to ABC News that he observed the shooter, identified as 24-year-old Chad Williams, aiming a rifle at passing vehicles outside the fast-food establishment. Salinas described Williams as initially composed and seemingly confident while targeting cars. However, that demeanor reportedly changed once Salinas began firing back in self-defense.

Salinas said the shooter’s “bravado immediately crumbled” when he realized he was being fired upon. The exchange of gunfire ultimately ended the attack, though specifics on how the confrontation concluded—including whether Williams was wounded or apprehended at the scene—were not disclosed by authorities in the immediate aftermath.

Emergency responders arrived quickly following the shooting, which occurred during the afternoon hours. Local law enforcement has not released further details regarding motives or the identities of the two victims killed in the attack, nor have they provided information about any additional injuries.

Investigators continue to examine the events leading up to the shooting, including the background of the suspect and any possible connections to the victims or the location. Officials emphasized their commitment to fully understanding the circumstances and preventing future incidents.

The prompt action of Salinas was credited with stopping further violence, illustrating the critical role bystanders can play during active shooter situations. Authorities encouraged anyone with information related to the event to come forward to aid the ongoing inquiry.
