On April 3, 2026, 40-year-old Brandon Lee Madden of Pocatello was one of two people killed in a shooting on Tank Farm Road about a mile north of the Simplot plant. Amanda Ann Christian, 36, was also found dead at the scene; a third person was wounded and taken to a local hospital in stable condition.

Responding officers searched for the shooter and located 63-year-old Richard Todd Forrest of Pocatello hiding near the Portneuf River. As officers closed in, additional shots were fired and a bystander in a boat on the river was struck and later discharged from the hospital. A police tactical team attempted negotiations, and officers ultimately engaged Forrest, who was fatally shot at the scene.

Multiple agencies including the Power County Sheriff’s Office, Bannock County Sheriff’s Office, and Idaho State Police handled the response. The investigation into the initial killings has been turned over to a multi-agency team. Did anyone in the Pocatello area see activity on Tank Farm Road or the Portneuf River that afternoon?
