Authorities in Dallas have identified one of the victims who died when a gunman opened fire on a U.S. Immigration and Customs Enforcement (ICE) facility on Wednesday as an illegal immigrant from El Salvador.

Norlan Guzman-Fuentes, 37, was in custody when he was killed during a sniper assault on the ICE Dallas Field Office. Guzman had been held by local law enforcement when ICE picked him up. 

According to ICE records, it is unknown when and where Guzman illegally entered the United States. However, his criminal history dated back to Feb. 19, 2012, when the Palm Beach County Sheriff’s Office in Palm Springs, Florida, arrested and charged him with battery, improper exhibit of a firearm or dangerous weapon and criminal mischief. All charges were dropped, except for the criminal.

On Feb. 14, 2020, the Arlington Police Department in Arlington, Texas, arrested and charged Guzman with driving while intoxicated. Guzman bonded out of custody before ICE was able to lodge a detainer.

On Sept. 24, Enforcement and Removal Operations (ERO) Dallas apprehended Guzman in accordance with a detainer for his apprehension. Upon arrival at the ERO Dallas Field Office, ICE officers encountered an active shooter at the facility, targeting immigration officials.

Officials said the suspect, 29-year-old Joshua Jahn, wanted to incite terror by killing federal agents. Jahn fatally shot himself following the assault.
