Bizarre radioactive fallout map taped to the side of suspected Dallas ICE facility shooter

Joshua Jahn, the 29-year-old suspect in the Dallas shooting at an Immigration and Customs Enforcement facility, had a bizarre poster taped to the side of his car during the attack.

The poster showed a map of "radioactive fallout" from "nuclear detonations" across the country. Most of the blasts were depicted on the West Coast.

The 29-year-old suspect reportedly shot himself after opening fire on the facility on Wednesday. No ICE officers were hurt in the shooting; however, two ICE detainees were killed, and a third is in critical condition, according to the Department of Homeland Security.

His brother Noah Jahn said he had not voiced opinions opposing the federal immigration enforcement agency and was not interested in politics, NBC News reported.

Kash Patel, the director of FBI, said that the investigation is ongoing however an initial review of the evidence shows an ''ideological motive behind this attack.''

Bullets were recovered near the suspect's body with "anti-ICE" written on them.

Texas Senator Ted Cruz condemned the attack on Wednesday and stressed that 'politically motivated violence is wrong' and added, 'political opponents are not Nazis. We need to work together without demonizing and attacking each other.'

No ICE officers were injured. Two ICE detainees were shot dead with a third critically injurered. The incident occured around 6:40 a.m. The suspected shooter was found dead from a self-inflicted gunshot wound.

The horrifying posted appears to be taped on the side of Joshua's car. Fox 4 reported that investigators have focused on a car parked outside a building next to the Dallas ICE facility, believed to belong to Joshua Jahn, the suspect.

'Radioactive fallout from nuclear detonations that've passed over these areas more than 2x since 1951', the poster reads.
