Part 4/11:
Law enforcement officials describe Yan's attack as a deliberate act of terrorism, motivated by anti-government sentiments and a desire to terrorize ICE employees nationwide. His handwritten notes uncovered during searches reveal explicit intentions to maximize lethality against ICE staff and to instill fear among federal agents.
One notable aspect of the evidence is a bullet recovered from the scene, inscribed with the words "anti-ice," suggesting ideological hatred. Yan also made statements indicating he believed he was carrying out a solitary act, as evidenced by notes saying “yes, it was just me.” While investigators found no evidence linking him to any specific militant group or broader conspiracy, his crude notes expressed a strong disdain for the federal government.
