Gunman wrote ‘ANTI-ICE’ on unused bullet in fatal attack on U.S. Immigration office

A gunman killed two detainees and wounded another on Wednesday, September 24 after opening fire on an Immigration and Customs Enforcement (ICE) field office in Dallas from a nearby rooftop before taking his own life, government officials confirmed.

FBI Director Kash Patel shared a photo on X of what he said were the suspect’s unspent shell casings, one of which had the words “ANTI-ICE” written along the side.

“While the investigation is ongoing, an initial review of the evidence shows an ideological motive behind this attack,” Patel wrote.

This morning just before 7am local time, an individual fired multiple rounds at a Dallas, Texas ICE facility, killing one, wounding several others, before taking his own life. FBI, DHS, ATF are on the ground with Dallas PD and state authorities.

The Department of Homeland Security stated that the suspect fired “indiscriminately” at the ICE building, including at a van in the secured entryway where the victims were shot. The wounded detainee remains in critical condition.

Multiple news outlets, identified the gunman as Joshua Jahn, 29.

His older brother, Noah Jahn, told a Reuters reporter he was unaware his brother harbored any negative political feelings toward ICE, stating, “I didn’t know he had any political intent at all.” FBI agents were later seen entering an address in McKinney, Texas, listed in online records for Joshua Jahn.

Authorities are treating the incident as an “act of targeted violence,” according to Joseph Rothrock, special agent-in-charge of the FBI’s Dallas field office. The shooting began from atop an adjacent building around 6:40 a.m. local time. Law enforcement officers were not injured in the attack, which took place at an ICE field office, where officers conduct short-term detainee processing.

This attack follows the recent fatal shooting of conservative activist Charlie Kirk and adds to the growing climate of political violence in the United States. The Trump administration has blamed, without providing public evidence, liberal organizations for fomenting unrest. President Trump recently signed an executive order declaring the anti-fascist movement, Antifa, a domestic “terrorist organization.”

Wednesday’s attack is the third shooting this year in Texas at a Department of Homeland Security facility.
