A gunman opened fire from a rooftop onto a U.S. Immigration and Customs Enforcement (ICE) field office in Dallas on Wednesday morning, killing two detainees, critically injuring another, and then taking his own life, authorities confirmed.

The FBI identified the shooter as 29-year-old Joshua Jahn of McKinney, Texas. Investigators said Jahn fired indiscriminately into the facility’s secured entryway around 6:40 a.m., striking a transport van carrying detainees. No ICE agents were injured.

In a statement, the Department of Homeland Security (DHS) said the shooter used a rifle and other weapons in what is being investigated as “an act of targeted violence.” FBI Director Kash Patel released a photo of an unused bullet casing recovered at the scene, marked with the words “ANTI-ICE.”

“This was a deliberate attack on a federal facility,” Joseph Rothrock, special agent-in-charge of the FBI’s Dallas field office, told reporters. “We are treating it as targeted violence with an ideological component.”

The incident occurred at the ICE field office located along Interstate 35 East, near Dallas Love Field airport. Witnesses described chaos as gunfire erupted. Edwin Cardona, a Venezuelan immigrant who was arriving with his son for an appointment, told the Associated Press: “I was afraid for my family because my family was outside. I felt terrible because I thought something could happen to them.”

Officials confirmed the shooter died by suicide on the roof of the adjacent building. FBI agents later searched a residence in McKinney linked to Jahn. His brother, Noah Jahn, told Reuters he was unaware of any political motives, saying, “I didn’t know he had any political intent at all.”

The attack follows a string of violent incidents targeting DHS facilities this year. On July 4, attackers opened fire outside the Prairieland Detention Center in Alvarado, wounding a police officer. Days later, a man with an assault rifle fired at federal agents near a U.S. Border Patrol station in McAllen, Texas, before being shot dead.

President Donald Trump and Vice President JD Vance condemned the shooting. “The obsessive attack on law enforcement, particularly ICE, must stop,” Vance wrote on X. Senator Ted Cruz of Texas echoed the call, urging politicians to “stop demonizing ICE and CBP.”

Wednesday’s shooting comes two weeks after conservative activist Charlie Kirk was killed by a rooftop sniper in Utah, heightening fears of escalating politically motivated violence nationwide.
