Recently released records provide insight into the gunman who attacked a Dallas immigration facility in September.
The parents of 29-year-old Joshua Jahn described him as "completely normal" before his move to Washington state and subsequent return home, where he believed he had radiation sickness.
According to a report by a Fairview Police Department officer, Jahn's behavior changed after his move and return.
Jahn's attack on a U.S. Immigration and Customs Enforcement building resulted in the deaths of two detainees and the wounding of another, before he took his own life.
The records, obtained through an open records request, do not reveal a clear motivation for the attack.
