A photo of the unspent shell casings was posted online by the bureau’s director.
FBI Director Kash Patel said on Sept. 24 that an unspent shell casing found after a shooting at a Dallas Immigration and Customs Enforcement office, which left one person dead and two injured, contained an “anti-ICE” message.
The suspect, who has not yet been identified and died of a self-inflicted gunshot wound, appeared to have an ideological motive for carrying out the shooting, Patel said in a post on X.
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.

“One of the unspent shell casings recovered was engraved with the phrase ‘ANTI ICE,’” Patel wrote, adding that it’s a part of a series of “despicable, politically motivated attacks” on law enforcement.
Patel also referred to a shooting at another ICE facility in Prarieland, Texas, in July.
“It has to end and the FBI and our partners will lead these investigative efforts to see to it that those who target our law enforcement are pursued and brought to the fullest extent of justice,” he said.
A photo that was posted by Patel shows five rounds in a stripper clip loading device. One of the rounds appears to say, “ANTI ICE” in blue lettering. It’s not clear whether any of the other rounds contained a message.
The FBI said during a news conference on Wednesday morning that it was investigating the shooting as “an act of targeted violence.”
“Early evidence that we’ve seen from rounds that were found near the suspected shooter contain messages that were anti-ICE in nature,” Joe Rothrock, special agent in charge of the Dallas field office, said during the press event.
The ICE facility is along Interstate 35 East, just southwest of Dallas Love Field, a large commercial airport serving the Dallas-Fort Worth metropolitan area, and just blocks from hotels catering to airport travelers.
Earlier Wednesday, Homeland Security Secretary Kristi Noem said details were still emerging, but the agency was confirming there were “multiple injuries and fatalities” at the field office. Noem said the motive remained unclear, but noted there has been an uptick in targeting of ICE agents.
“While we’re not releasing identities of any victims at this time, what I can confirm for you is no members of law enforcement were hurt during this attack,” Rothrock added during the news conference.
He also appealed to the public for more assistance
