Dallas ICE shooter Joshua Jahn’s car had bizarre map showing nuclear fallout

DALLAS, TEXAS: A sniper-style attack on an Immigration and Customs Enforcement (ICE) facility rattled Dallas on Wednesday, September 24, 2025.

The shooter, identified as 29-year-old Joshua Jahn, opened fire from a rooftop into a detainee transport van, killing one person and leaving two critically injured before turning the gun on himself.

Authorities later discovered a nuclear fallout map in Jahn’s car, suggesting a disturbing layer to his planning. Federal officials now believe the assault was a meticulously plotted act of domestic terrorism.

Nuclear fallout map discovery deepens mystery

The most bizarre evidence came from Jahn’s Toyota Corolla parked near the attack site.

Inside, agents discovered a nuclear fallout map detailing radioactive cloud patterns from US tests dating back to 1951.

Authorities are investigating whether the map symbolized Jahn’s belief in looming catastrophe or served as a twisted metaphor for federal “contamination.”

The discovery has fueled speculation about Jahn’s psychological state, with one FBI analyst noting it “blends ideology with paranoia.”

 'ANTI-ICE' ammo points to motive

Law enforcement sources revealed that Jahn’s ammunition casings were etched with “ANTI-ICE,” a chilling signal that his anger was directed squarely at the federal agency.

Investigators later uncovered writings at his residence that condemned ICE personnel as “dirty paycheck earners” and portrayed the agency as “the enemy within.”

Court records indicate Jahn had no prior criminal convictions but had shown signs of radicalization in recent years.

He reportedly consumed hours of online forums focused on anti-government movements and sniper training manuals, suggesting the shooting was the culmination of months of preparation rather than a spontaneous act.

Deadly morning ambush

The assault began just after 6:40 a.m. as an ICE transport van arrived at the Dallas facility.

Witnesses said Jahn, positioned on a nearby rooftop, fired multiple rounds directly into the van’s windows.

One detainee was killed instantly, while two others sustained critical injuries. Emergency crews rushed the victims to a local hospital, where they remain under intensive care.

FBI Dallas chief Marcus Rowe confirmed that no ICE agents were struck, adding that the gunman’s choice of target suggested he wanted to send a message rather than achieve maximum casualties.

Federal response and political fallout

The FBI has classified the shooting as domestic terrorism, citing Jahn’s anti-ICE writings and deliberate planning. Acting US Attorney Nancy Larson told reporters that the attack was intended to “instill fear in federal officers and the communities they serve.”

The incident has already ignited fierce political debate. President Donald Trump accused “Radical Left Democrats” of creating an atmosphere that emboldens anti-ICE extremists.

Homeland Security Secretary Kristi Noem vowed immediate upgrades in ICE facility security nationwide.

Critics, however, warned that both parties are exploiting the tragedy to score political points instead of addressing the underlying extremism.
