(NewsNation) — Authorities have identified the suspected shooter at the Dallas Immigration and Customs Enforcement Field Office where one detainee was killed and two others were critically injured on Wednesday as Joshua Jahn, NewsNation has confirmed.
Sources told NewsNation that Jahn, 29, resided in Collin County, located northeast of Dallas. Jahn was previously arrested and charged with possession of drug paraphernalia and dealing marijuana.
Dallas Police Chief David Cormeaux told a local television station that authorities are looking into the possibility that Jahn was living in Durant, Oklahoma.
DHS officials said in a statement before Jahn was publicly identified as the shooter that a sniper had fired “indiscriminately” at the ICE facility. The detainees who were shot in or near a van that was parked near the ICE field office, which is used as a processing center for those taken into federal custody by immigration officers and agents.
Jahn was found dead by officials shortly after the shooting, which took place at around 6:40 a.m. on Wednesday.
FBI Director Kash Patel posted photos of the bullet casings found near the shooter. One of the casings read “anti-ICE”. Secretary of Homeland Security Kristi Noem posted on X that she has been warning politicians and the media for months to “tone down their rhetoric” about ICE before someone was killed.
“These horrendous killings must serve as a wake-up call to the far-left that their rhetoric about ICE has consequences.” Noem wrote. “Comparing ICE day in and day out to the Nazi Gestapo, the Secret Police, and slave patrols has consequences.”
Jahn’s older brother, Noah Jahn, told Reuters he was not aware that his brother harbored any negative feelings about ICE.
“I didn’t know he had any political intent at all,” said the older brother, who lives in McKinney, Texas, around 30 miles north of Dallas, as did his sibling.
The FBI declined to identify the three victims of the shooting, which Texas Gov. Greg Abbott characterized as “an assassination”.
“This assassination will NOT slow our arrest, detention, & deportation of illegal immigrants,” Abbott wrote on X. “We will work with ICE & the Dallas Police Dept. to get to the bottom of the assassin’s motive. We will offer ICE additional support to assist their operations.”
