Sometime in the early morning hours of Wednesday, September 24, 2025, Joshua Jahn was seen driving through Dallas with a long ladder. He arrived near the Dallas ICE field office and used that ladder to climb to the roof of a nearby office building. He positioned himself with clear sight lines to the ICE facility's sallyport — the enclosed vehicle bay where detainees are loaded into and off transport vehicles. He had researched the building. He had tracked the location of ICE agents. He knew that transport vehicles carrying ICE personnel, federal agents, and detainees would be in that location that morning.
At approximately 6:30 AM CDT, he opened fire.
Jahn shot "indiscriminately" toward the sallyport. He fired multiple rounds at the transport vehicles. He also fired multiple shots into the windows of the ICE office building where ICE employees work. When ICE and ATF agents heard the gunfire, they ran toward the vehicles and put themselves in the line of fire to pull people off the transport vehicles. They were trying to protect and rescue the injured.
One ICE detainee was killed. Two others were critically wounded. Not a single law enforcement officer was shot. All three victims were detainees of the facility — the very population Jahn's anti-ICE ideology claimed to defend.
Dallas Police Department and the Dallas County Sheriff's Office responded immediately and ran toward the sound of gunfire. They located the shooter on the rooftop — deceased from a self-inflicted gunshot wound. Joshua Jahn was 29 years old.
