The "Ice Shooter" refers to Joshua Jahn, a 29-year-old who opened fire from a rooftop at a U.S. Immigration and Customs Enforcement (ICE) facility in Dallas, Texas. Jahn fired indiscriminately, killing one detainee and critically injuring two others before turning the gun on himself. He left a handwritten note expressing a desire to instill "real terror" among ICE agents, referring to the use of armor-piercing rounds and indicating premeditation. Jahn had searched for information on ballistics and monitored apps tracking ICE personnel prior to the attack, suggesting a targeted act of violence against ICE facilities and its agents.
