The parents of the 29-year-old gunman who opened fire on a Dallas immigration facility in September told police their son was “completely normal” before he moved to Washington state and returned home several years ago believing he had radiation sickness, according to newly released records.
Joshua Jahn had begun wearing cotton gloves to avoid contact with plastic and practiced target shooting with a newly purchased rifle in Oklahoma a month before the deadly rooftop attack on a U.S. Immigration and Customs Enforcement building, according to a report written by a Fairview Police Department officer.
Jahn killed two detainees and wounded another before taking his own life in the Sept. 24 shooting.
The records, obtained by The Associated Press through an open records request, reveal no clues about what may have motivated the attack. Federal authorities said previously that Jahn wrote “ANTI-ICE” on a bullet and left handwritten notes indicating he wanted to ambush and terrorize ICE agents.
The new records show that on the day of the shooting, Jahn’s parents told the FBI he would “occasionally discuss current events” with his mother but rarely engaged in conversations. His parents said he was a “loner” who was “obsessed” with artificial intelligence technology. The parents, Andrew and Sharon Jahn, did not immediately respond Monday to text and phone messages from the AP.
