Overview

  • The Fairview Police records obtained by the Associated Press describe Joshua Jahn, 29, as unemployed, withdrawn, fixated on AI, and heavily gaming in his bedroom, with no diagnoses reported by his parents.
  • His parents told authorities he believed he had radiation sickness after time in Washington state and wore cotton gloves to avoid touching plastic; his car displayed a radioactive fallout map.
  • About a month before the attack, Jahn practiced target shooting in Durant, Oklahoma, after buying a rifle online, and officials said he legally obtained a bolt-action rifle in August.
  • Evidence recovered includes a casing marked “ANTI-ICE” and notes about ambushing ICE agents, yet the victims were detainees in a transport van, with Miguel Ángel García-Hernández and Norlan Guzmán-Fuentes killed and Jose Andres Bordones-Molina wounded.
  • Federal agents continue the investigation and security remains heightened at ICE facilities, while the FBI has limited public comment during the government shutdown.
