The gunman who opened fire on a U.S. Immigration and Customs Enforcement (ICE) field office in Dallas acted alone, according to notes found at his home, which stated his attack was intended to terrorize ICE agents and minimize harm to detainees. This information emerged during the reporting window of approximately 9:37 PM to 11:07 PM UTC on September 25th, 2025. ICE officials, speaking at a joint press conference in Dallas earlier on September 25th, 2025, commended officers who responded to the gunfire. Marcos Charles, an ICE representative, stated that the agency "will not be deterred, but this violence and hateful rhetoric must end." The timing of the press conference falls within the broader context of the day's events, following the earlier confirmation by Acting U.S. Attorney Nancy Larson that the shooting was an act of terrorism. Previous reports from September 25th, 2025, indicated that the FBI had been investigating extensive pre-attack planning by the individual, including searches for ballistics and targeting ICE agents. The specific timing of the shooting itself within the day was not previously provided. The notes found at the suspect's home suggest his intent was to inflict "real terror" on agents, whom he accused of "human trafficking," and that detainees were not the intended targets. In other developments on September 25th, 2025, a major 911 outage affected much of Louisiana and Mississippi due to a fiber cut, officials confirmed. Separately, Sean "Diddy" Combs appeared for a hearing in Lower Manhattan, an armed woman was arrested in Gwinnett County, and unidentified drones were observed over a French military base.
