Dallas ICE Shooter’s Handwritten Notes Revealed

Jahn allegedly left handwritten notes behind that read in part, "Hopefully this will give ICE agents real terror, to think, ‘Is there a sniper with AP rounds on that roof?’"

"To include Jahn's own words in his handwritten notes, Jahn specifically intended to kill ICE agents. He fired at transport vehicles carrying ICE personnel, federal agents, and detainees. He also fired multiple shots into the windows of the office building, where numerous ICE employees do their jobs every day," Rothrock said during a news conference.

"He searched for information about the office building and how to track ICE agents' locations. Jahn also acknowledged the potential for other casualties. He knew with a high likelihood ICE detainees would be transported that morning in the exact location where he was facing from his perch on a nearby rooftop. Jahn's attack did, in fact, result in the tragic death of one detainee and the injury to two other detainees," Rothrock said.

"He called the ICE employees people showing up to collect a dirty paycheck. He wrote that he intended to maximize his lethality against ICE personnel and to maximize property damage at the facility. He hoped to minimize any collateral damage or injury to the detainee and any other innocent people," said Nancy Larson, the Acting U.S. for the Northern District of Texas. "He also hoped his actions would give ICE agents real terror of being gunned down. And he did this to undo constant stress in their lives. He hoped his actions would terrorize ICE employees and interfere with their work, which he called human trafficking. And this what he did is the very definition of terrorism. Again, his notes reveal, ‘Yes, it was just me and my brain.’ And he said, ‘Good luck with the digital footprint.’ And of course, we take this to mean that he deleted evidence from his devices."

"Federal law enforcement, particularly the Department of Justice, needs to be focusing on international terrorism and domestic terrorism and find out what motivates each of those different attacks on our country. And of the two between international terrorism and domestic terrorism, the one that scares me more is domestic terrorism. And so we have to start digging in. What motivates these people — whether they are on the left, whether they are on the right — to take these kinds of actions," he said.

"I want to address the heroism of our federal agents. Yesterday, while under fire, ICE agents and ATF agents who were also present in the facility, the sally port Area worked together to remove detainees from the vans and get them to safety while the bullets were flying. These agents were heroic, clearly willing to lay down their lives to save the lives of the detainees in their custody. And that's an extremely important point to make at this point in time. I want to express my deepest appreciation for the bravery of these law enforcement officers yesterday and every single day that they go out there to keep us safe," Larson said.

"Those ICE officers just showed the world who they really are – law enforcement officers who want the best for our country. That's ICE. Integrity. Courage. Excellence," added Marco Charles, the Dallas ICE field office director of Enforcement and Removal Operations.
