Newly released police and FBI records reveal disturbing details about Joshua Jahn, the 29-year-old gunman who killed two detainees and wounded another before taking his own life in a September attack on a Dallas immigration facility.
According to documents obtained by the Associated Press, Jahn’s parents told investigators their son had been “completely normal” until he returned from Washington state several years ago claiming he was “allergic to plastic” and suffering from “radiation sickness.” The couple said he wore cotton gloves to avoid contact with plastic and spent most of his time isolated in his bedroom, playing video games.
On Sept. 24, Jahn climbed onto the roof of a U.S. Immigration and Customs Enforcement building in Dallas and opened fire with a bolt-action rifle. The attack killed two detainees—Norlan Guzman-Fuentes, 37, from El Salvador, and Miguel Angel Garcia-Hernandez, 32, from Mexico—and injured a third, identified as Jose Andres Bordones-Molina.
Investigators say Jahn left behind bullets labeled “ANTI-ICE” and handwritten notes indicating he wanted to “ambush and terrorize ICE agents.” Despite these writings, authorities have not established a clear motive for the attack.
