The mass shooting at the In‑N‑Out Burger in Twin Falls, Idaho on Aug 1 2026 has been further detailed. Police Chief Matthew Hicks confirmed that 24‑year‑old Chad Williams opened fire inside and outside the restaurant, killing three people—including an employee—and wounding seven, two critically. An off‑duty Idaho State Police trooper and armed civilian Jordan Salinas returned fire, forcing Williams to retreat; he later died from a self‑inflicted gunshot wound near the scene. The FBI is conducting a joint investigation with local agencies, gathering video and photo evidence, and has warned the public about online misinformation that misidentified the shooter. In‑N‑Out president Lynsi Snyder expressed heartbreak and urged prayers for the victims. Authorities say the shooter’s family is cooperating, and police have interviewed hundreds of witnesses as the community mourns and begins to recover.
