Authorities have identified Joshua Jahn, 29, as the gunman behind Wednesday’s fatal shooting near a Dallas ICE field office. Jahn reportedly opened fire from a rooftop at an ICE transport van, killing one detainee and injuring two others before taking his own life.

Investigators found spent shell casings marked with anti-ICE messages, labeling the attack a direct assault on federal law enforcement.

President Donald Trump called the incident “despicable” in a statement, while Homeland Security Secretary Kristi Noem urged the public to pray for the victims and demanded an end to violence targeting ICE officers.

Jahn’s family expressed shock, describing him as non-political and deeply into online gaming. Court records show a past drug-related charge, but no history of violent behavior. His brother said Joshua had been planning to move to their parents’ property in Oklahoma.

Witnesses described terrifying moments as rapid gunfire rang out, with some sheltering in cars while others fled. Bomb squads later investigated a suspicious vehicle and multiple properties linked to Jahn.

Authorities continue to investigate the motive behind the attack as the community grapples with the tragedy.
