Overview

• Joshua Jahn, 29, was identified as the rooftop gunman and died of a self‑inflicted gunshot after the assault.
• Gunfire struck detainees in a transport van at a secure gate, killing one person and critically injuring two, while no ICE staff were wounded.
• The FBI says Jahn acted alone, legally purchased an 8‑mm bolt‑action rifle in August, and researched DHS locations and ICE activity.
• Recovered writings expressed a desire to cause "true terror" to ICE agents, and officials are investigating the act as targeted violence.
• DHS ordered heightened security at ICE facilities nationwide, and Mexico’s foreign ministry says a wounded victim is a Mexican national in critical condition.
