For the second time in two weeks a shooter on a rooftop inflicted death on the ground, this time at a U.S. Immigration and Customs Enforcement facility in Dallas where a detainee was killed and two others were critically wounded by a gunman who then fatally shot himself.

Axar.az informs, citing ABC news, the Department of Homeland Security said in a statement that shots were fired early Wednesday “indiscriminately at the ICE building, including at a van in the sallyport,” a secure and gated entryway. The detainees were in the van. No ICE personnel were injured.

The shooter was identified as 29-year-old Joshua Jahn by a law enforcement official who could not publicly disclose details of the investigation and spoke to The Associated Press on condition of anonymity. Investigators were seeking to determine the motive.

FBI Director Kash Patel posted a photo on social media showing a bullet found at the scene with “ANTI-ICE” written on it. Homeland Security Secretary Kristi Noem ordered more security at ICE facilities across the U.S., according to a post by the DHS on the social platform X.

Authorities have given few details about the shooting and did not publicly release the names of the victims or the gunman. The FBI said it was investigating the shooting as “an act of targeted violence.”
