U.S. Attorney for the Northern District of Texas Nancy Larson said that Joshua Jahn – the sniper who ambushed a Dallas ICE facility – was aiming to kill agents.

In a press conference on September 25, Larson said he left behind notes expressing a deep hatred for ICE.

“It’s clear from these notes that he was targeting ICE agents and ICE personnel,” Larson said. “What he did is the very definition of terrorism.”

Jahn fired repeatedly at the ICE facility from a rooftop early September 24, killing one detainee and critically injuring two others, as The Dallas Express previously reported. He arrived with a ladder on his car, which he apparently used to scale a nearby building, Larson said in the recent press conference. 

“Gunshots sprayed the length of the building, the windows, and law enforcement vans,” she said. “These agents were heroic, clearly willing to lay down their lives to save the lives of the detainees in their custody.”

Jahn ultimately turned the gun on himself. He left bullets nearby, one of which read “ANTI-ICE.”

Authorities obtained and executed multiple search warrants that day for Jahn’s devices and associated locations, according to Larson. As Fox 4 reported, the shooter was linked to one home in Fairview and another in Durant, Oklahoma.

FBI agents searched Jahn’s home, where they found a “collection of notes.” On one of these papers, he wrote, “Yes, it was just me and my brain.” He had written out a strategy for the attack and named specific targets.

Marcos Charles, acting executive associate director for ICE Enforcement and Removal Operations, stated during the press conference that the suspect had used ICE tracking apps. As The Dallas Express previously reported, anti-enforcement actors in the metroplex have been using apps like “ICE Block” to monitor federal activity.

“Anyone who creates or distributes these apps that are designed to spot, track, and locate ICE officers are well aware of the dangers that they are exposing to law enforcement,” Charles said. “It’s no different than giving a hitman the location of their intended target, and this is exactly what we saw happen in Dallas yesterday.”

Jahn wanted to “maximize lethality” against ICE personnel, but “minimize collateral damage to detainees or others,” according to Larson.

“He also hoped his actions would give ICE agents a real terror of being gunned down, and he did this to induce constant stress in their lives,” she said. “He hoped his actions would terrorize ICE employees and interfere with their work, which he called ‘human trafficking.’”

Jahn reportedly wrote, “Good luck with the digital footprint,” according to Larson.

“We take this to mean that he deleted evidence from his devices,” she said. 

While Jahn apparently deleted his Facebook page, some individuals have been posting images of a profile with Antifa and communist symbols. The Dallas Express has not independently verified those claims. 

Investigators also found a map of radioactive fallout across the nation, taped to the rear quarter panel of Jahn’s blue Toyota Corolla, as previously reported by The Dallas Express. He was previously arrested in Collin County in 2016 on a felony charge for delivering marijuana and received five years of “deferred adjudication” probation with fines and restitution. 

This marks at least the third recent attack on ICE or Customs and Border Protection in Texas. Militants linked to Antifa ambushed an ICE facility in Alvarado on July 4, and a suspect fired at a CBP station in McAllen just days later, on July 7. 

The shooting also came just two weeks after a leftist assassinated Charlie Kirk, amid what Kirk himself once called a growing “assassination culture.”
