Dallas
Joshua Jahn, a 29-year-old gunman, opened fire at a Dallas immigration facility on September 24, killing two detainees and wounding another before taking his own life. The Department of Homeland Security (DHS) confirmed that the facility encountered an active shooter targeting immigration officials upon arrival. Law enforcement found Jahn dead at the scene, and officials later confirmed one wounded detainee and two fatalities among detainees.
Immediate details and victims
Following the shooting, ICE confirmed that Miguel Ángel García-Hernández died after being removed from life support, making him the second fatality of the attack, alongside Norlan Guzmán-Fuente. Authorities continue to investigate the sequence of events inside the facility and to review evidence collected at the scene, including a vehicle linked to the shooter.
Suspect background and behavior
Records and statements compiled by investigators and family members depict Jahn as increasingly withdrawn in the months before the attack. Jahn’s parents described him as completely normal before he returned from Washington state, where he believed he had radiation sickness. After returning to Texas, Jahn reportedly adopted behaviors intended to limit skin contact with certain materials; he had begun wearing cotton gloves to avoid contact with plastic and publicly expressed a belief that he was affected by exposure while working in Washington.
Further records show that he had moved to Washington to take a seasonal job harvesting marijuana at a legal cannabis farm but struggled to retain employment, ultimately returning to Texas. Back in Texas, he lived at his parents’ home in a Dallas suburb and was largely unemployed. Records portray Jahn as unemployed, friendless, and withdrawn, spending much of his time playing computer games at his parents’ home in a Dallas suburb.
Online activity and interests
Investigators examined Jahn’s online presence and gaming history. Jahn logged over 11,000 hours on various first-person shooter and survival games on the platform Steam. Analysts from the Institute for Strategic Dialogue indicated Jahn played online games under the username Frank Hoenniker, a name loosely referencing a character from Vonnegut’s novel Cat’s Cradle. Reports further describe him as deeply interested in technology, with witnesses describing him as a loner who was reportedly obsessed with artificial intelligence technology.
Motive indicators and writings
Federal authorities reviewed writings and materials linked to Jahn as part of the investigation into motive. Jahn’s writings were described as definitively anti-ICE with indications of hatred for the federal government, according to federal authorities. Investigators are continuing to assess those materials alongside physical evidence from the scene.
Weapon, training and items found
Investigators reported that Jahn had participated in target shooting with family members and had recently acquired the firearm used in the attack. Jahn participated in target shooting with his father and had recently purchased the bolt-action rifle used in the shooting. Family members provided background indicating limited social ties and intermittent college enrollment; his parents stated that he had taken classes at a Texas community college intermittently over several years.
At the scene, authorities found a vehicle linked to Jahn that contained additional material of interest. A car belonging to Jahn was found at the shooting scene, displaying a map of radioactive fallout in the US. Investigators also note that his mother claimed she had no idea her son owned a gun, and law enforcement noted that Jahn legally obtained the firearm.
Family context and mental health
Family records and statements to investigators indicate tensions within the household before the shooting. Jahn’s family life was reportedly troubled, with pressure from his father on his older brother regarding employment and military enlistment. Despite concerning behavior and beliefs reported by family members, despite his unusual behavior, Jahn was not diagnosed with any mental or physical disorders, according to his parents.
Ongoing investigation
Federal and local authorities continue to investigate the attack, examining Jahn’s writings, online activity, employment history, and movements in the weeks before September 24. Families of victims have called for full investigations into motive and circumstances surrounding the attack. García-Hernández’s family expressed their devastation, highlighting the tragedy as senseless and urging for investigations into the motives behind the violence.
