Initial Coverage
A shooter killed one detainee and wounded two others Wednesday morning at an Immigration and Customs Enforcement (ICE) facility in Dallas.
Early reports said that two detainees were killed, but that number was later revised. The two wounded detainees are in critical condition.
The shooter was found dead from a self-inflicted gunshot wound in the roof of an adjacent building, WFAA reported.
The shooter opened fire as a bus of detainees was being loaded or unloaded at around 7 a.m., sources told the station. No law enforcement agents were hit by gunfire, ICE’s acting director, Todd Lyons, said.
According to NBC News, the shooter opened fire on the facility’s secure sally port from an elevated position. The third person hit by gunfire was also a detainee.
A DHS official said the facility was a field office and not a detention center.
A massive police response closed Interstate 35 in the area as police checked to see if there were other shooters, as they always do in such situations.
Homeland Security director Kristi Noem said in a social media post that there were “multiple injuries and fatalities.” She also confirmed the shooter’s death by suicide, and she decried “unprecedented violence” against ICE agents, even though no law enforcement agents were killed or injured. She did acknowledge that a motive for the shooting was not yet known.
FBI director Kash Patel posted a photo a bullets he said belonged to the suspect, claiming there is an “ideological motive” to the attack, which only hit detainees and not ICE agents. One of them had the phrase “anti-ICE” in blue ink.
The police response was reminiscent of the shooting at the Centers for Disease Control and Prevention in Atlanta last month, when a man with anti-vaccination views opened fire at the facility, killing a police officer who responded and ultimately firing 500 rounds at the building.
