A gunman opened fire at the newly opened In‑N‑Out Burger in a busy shopping area of Twin Falls, Idaho, killing three people and injuring at least two others before dying at the scene, with witnesses reporting a man armed with an AR‑style rifle emerging near the drive‑thru and rapid gunfire sending customers running for cover as police shut down nearby roads and the Perrine Bridge and St. Luke’s Magic Valley hospital treated the wounded.
