A second detainee has died after a shooter opened fire on a Dallas Immigration and Customs Enforcement (ICE) facility last week, the Department of Homeland Security confirmed to Fox News.

The League of United Latin American Citizens (LULAC) identified the victim as Miguel Ángel García-Hernández, 32, who they said died after being removed from life support following the Sept. 24 sniper attack.

García-Hernández leaves behind four young children and his wife, who is expecting their fifth child.

Officials said Joshua Jahn, 29, carried out the sniper assault and wanted to incite terror by killing federal agents. Jahn fatally shot himself following the attack.

The shooting happened while ICE officers were bringing detainees into the agency’s Dallas facility. ICE sources told Fox News the detainees were inside a law enforcement van when the gunfire erupted. Federal officials said anti-ICE messaging was engraved on rounds found near Jahn’s body.

FBI Director Kash Patel said Jahn downloaded a document before the attack titled “Dallas County Office of Homeland Security & Emergency Management,” which listed DHS facilities.

Between Aug. 19 and Aug. 24, Jahn also searched apps that tracked the presence of ICE agents, Patel said. In the hours before the shooting he looked up ballistics information and the “Charlie Kirk Shot Video.”

Investigators also recovered a handwritten note in which Jahn wrote: “Hopefully this will give ICE agents real terror, to think, ‘is there a sniper with AP rounds on that roof?’” Patel said evidence gathered so far indicates a “high degree of pre-attack planning.”
