The shooter who opened fire at an Immigration and Customs Enforcement detention facility in Dallas spent a “significant” amount of time planning the lone-wolf attack on ICE personnel and left a note saying he wanted to “maximize lethality,” officials said Thursday.
Joshua Jahn, 29, of Fairview, Texas, killed one ICE detainee and injured two others after opening fire around 6:30 a.m. Wednesday. Jahn died from a self-inflicted gunshot wound, the FBI said. Law enforcement did not provide details about the victims’ identities or their conditions.
