(NEXSTAR) – An unspent casing found while investigating a shooting at a U.S. Immigration and Customs Enforcement facility in Dallas on Wednesday had the message "ANTI-ICE" written on it, FBI Director Kash Patel said.
Three people were shot at the ICE facility Wednesday in what officials believed to be a targeted attack. One has died and two were in critical condition at the hospital, the Department of Homeland Security said. The Department mistakenly said two had died before issuing a correction at 2:30 p.m.
All three people hit were detainees, according to DHS.
The shooter was also dead from a self-inflicted gunshot wound.
Sharing a photo of the bullets on X, Patel said, "While the investigation is ongoing, an initial review of the evidence shows an idealogical [sic] motive behind this attack."
No ICE agents were injured in the shooting.
“The shooter fired indiscriminately at the ICE building, including at a van in the sallyport where the victims were shot,” DHS said in a release.
The rounds were found near the suspected shooter, said Joe Rothrock, special agent in charge of the Dallas field office, in a press conference.
Officers responded to a call to assist an officer on North Stemmons Freeway around 6:40 a.m. Wednesday, and the preliminary investigation determined that a person opened fire at a government building from an adjacent building.
The attack is the latest public, targeted killing in the U.S. and comes two weeks after conservative leader Charlie Kirk was killed by a rifle-wielding shooter on a roof.
The motive in Wednesday's shooting is still being investigated, but Vice President JD Vance said he was "pretty confident this was a motivated, left-wing political attack" in an interview with Nexstar.
"I think [it] goes to show that we have way too much of this in our country, especially the last couple weeks," Vance said. "I think we all need to tone down the temperature a little bit."
