NEW: FBI Reveals ICE Shooter’s Hand-Written Note, Unsettling Search Related To Charlie Kirk

FBI Director Kash Patel revealed on Thursday that Joshua Jahn, the gunman who shot up a U.S. Immigration and Customs Enforcement facility in Dallas, Texas, sought “real terror” for agents and “searched apps that tracked the presence” of ICE personnel.

Jahn opened fire from a nearby rooftop toward the facility and killed one detainee, along with injuring two others. He then shot himself when confronted by authorities.

“FBI Dallas and FBI HQ have been working 24/7 to seize devices, exploit data, and process writings obtained on location and in the subject’s person/residence/bedroom,” Patel said in a post on X. “One of the handwritten notes recovered read, ‘Hopefully this will give ICE agents real terror, to think, ’is there a sniper with AP [armor-piercing] rounds on that roof?'”

“He conducted multiple searches of ballistics and the ‘Charlie Kirk Shot Video’ between 9/23-9/24,” Patel’s post continued. “Between 8/19-8/24, he searched apps that tracked the presence of ICE agents.”

The FBI director then revealed that the shooter also downloaded “a document titled ‘Dallas County Office of Homeland Security & Emergency Management’ containing a list of DHS facilities.”

Jahn also “further accumulated evidence [that] to this point indicates a high degree of pre-attack planning.”

“Patel also said that the gunman searched for videos of Charlie Kirk’s assassination in Utah leading up to the attack in Dallas on Wednesday,” Fox News reported.

Jahn is said to have allegedly fired his weapon “indiscriminately” at the facility, also taking several shots at a van that was located in the sally port, which is where the victims were shot, information released by Homeland Security said.

All three of the detainees were in an unmarked transport van when they were shot, just before Jahn committed suicide sometime around 7 a.m.

Shell casings found at the scene were covered in anti-ICE messages. Patel shared a photograph of the casings on his X account.

Jahn, who lived in a suburb of Dallas, was charged with crimes related to the delivery of marijuana over a decade ago, according to court records. The charges, dating from 2016 when Jahn was 19, revealed that he delivered over a fourth of an ounce of marijuana.

He ultimately pleaded guilty and the case was then deferred. Jahn was placed on probation for his crime. According to Ryan Sanderson, the owner of a legal cannabis farm in Washington state, Jahn drove across the country to work for minimum wage harvesting marijuana.

“He’s a young kid, a thousand miles from home, didn’t really seem to have any direction, living out of his car at such a young age,” Sanderson said in an interview with the AP.

Voter information shows that Jahn participated in the Democratic primary in March 2020, but had not cast a ballot since then.
