Twin Falls Police Chief Matthew Hicks announced the identification during a Sunday, Aug. 2, press conference. The video then showed Williams lowering the rifle, moving away from the vehicle, and running across the parking lot while still carrying the firearm. One In-N-Out employee reportedly dragged a wounded co-worker across the parking lot while others provided assistance until paramedics reached the scene. Among those injured was Twin Falls taxi driver Terry Dudley. Saturday's attack is among the deadliest shootings to strike Twin Falls in recent years and drew a significant response from local law enforcement and emergency personnel.
