Overview
- The shooting began at the In‑N‑Out drive‑thru on Aug. 1 when a lone gunman opened fire, killing three people and wounding multiple others.
- Twin Falls police on Aug. 7 showed compiled surveillance and officer body‑worn camera video that traces the gunman firing through the payment window, experiencing a handgun jam, returning to his car to retrieve a rifle, and shooting at vehicles and nearby sites.
- Authorities identified the suspect as 24‑year‑old Chad Williams, who died of a self‑inflicted gunshot as officers closed in, and said they have no confirmed motive while the FBI assists the ongoing investigation.
- Police credited acts by an off‑duty Idaho state trooper, a former Twin Falls officer (Austin James), at least one armed civilian, and a nearby employee who confronted the shooter with helping limit further harm; several interveners were wounded.
- The three people killed were named by police and communities have held vigils; investigators are collecting more video and witness statements and have urged the public to submit footage and avoid spreading unverified claims.
