Dallas ICE facility shooting suspect Joshua Jahn downloaded and used ICEBlock to locate ICE officers
Federal investigators are examining whether a controversial app promoted earlier this year played a role in last week’s deadly attack at an Immigration and Customs Enforcement (ICE) facility in Dallas.
The suspect, identified as 29-year-old Joshua Jahn, opened fire from the rooftop of a nearby building at approximately 6:40 a.m. on September 24, targeting an ICE field office and an unmarked transport van carrying detainees.
The sniper attack left two detainees dead, a third critically injured, and Jahn himself deceased from a self-inflicted gunshot wound.
According to FBI Director Kash Patel, Jahn’s digital activity revealed extensive pre-attack research.
Investigators found evidence that he downloaded and used ICEBlock, a mobile app designed to crowdsource and share the real-time locations of ICE officers.
The app allows users to anonymously pin ICE sightings on a map, sending alerts to anyone within a five-mile radius.
CNN featured the app in June, shortly after its April launch, describing it as an “early warning system” for undocumented migrants seeking to avoid enforcement.
Developer Joshua Aaron was interviewed in the report, which drew sharp criticism from federal officials.
At the time, ICE Acting Director Todd Lyons denounced CNN’s coverage, calling it “reckless and irresponsible.” He warned, “Advertising an app that basically paints a target on federal law enforcement officers’ backs is sickening.” White House Press Secretary Karoline Leavitt also condemned the platform, stating that it “encourages violence against law enforcement officers who are trying to keep our country safe.”
Director Patel now says Jahn’s online activity corresponded with a spike in downloads of ICEBlock following CNN’s story.
His searches also included a DHS facility directory in Dallas County, research into ballistics, and case studies of prior mass shootings.
“This indicates a high degree of pre-attack planning,” Patel said, noting that Jahn appeared specifically focused on federal immigration enforcement.
At the scene, investigators recovered unspent rifle rounds engraved with anti-ICE slogans and a handwritten note in which Jahn expressed a desire to instill “real terror” among immigration officers.
The Dallas attack marks the fourth violent incident at a Department of Homeland Security facility in Texas this year.
DHS officials say threats and attacks targeting ICE personnel have surged by more than 1,000% in recent months, prompting immediate nationwide security enhancements.
City of Hammond, Louisiana — At approximately 11:50 p.m. on February 24, 2026, officers with the Hammond Police Department responded to a report of shots fired involving one possible victim.
Upon arrival, officers located a 14-year-old juvenile female, identified as Tyronai Reed, suffering from an apparent gunshot wound.
Emergency medical assistance was rendered at the scene, and she was transported to North Oaks Health System for treatment.
Despite life-saving efforts, Reed later succumbed to her injuries.
Detectives assigned to the department’s Criminal Investigations Division launched an immediate homicide investigation.
During the course of their investigation, authorities identified 18-year-old Demontez Treyvon “Trey” Robinson of Hammond as a suspect in the shooting.
While actively working the case, officers observed a vehicle traveling at a high rate of speed and conducted a traffic stop.
Robinson was identified as the driver of the vehicle and was taken into custody without incident.
Robinson was transported to the Criminal Investigations Division for questioning. According to investigators, Robinson admitted that the firearm discharged while he was handling or “playing with” it, resulting in the single round striking the 14-year-old victim.
Robinson was subsequently booked into the Hammond City Jail on one count of Negligent Homicide.
Authorities emphasize that the investigation remains in its early stages and additional details may be released as they become available.
