Authorities identified the man who opened fire on an Immigration and Customs Enforcement facility in Dallas on Wednesday as Joshua Jahn, a 29-year-old with ties to Texas and Oklahoma.

Mr. Jahn, who died of a self-inflicted gunshot wound, was a white male with a criminal record from a marijuana conviction in 2016.

Public records say he was registered as an independent and last voted in 2024, as authorities investigate a political or ideological motive behind the shooting that killed two migrant detainees and wounded another.

Authorities said Mr. Jahn then took his own life.

“He didn’t have strong feelings about ICE as far as I knew,” Noah Jahn, his older brother, told NBC News.

“I didn’t think he was politically interested,” Noah Jahn said. “He wasn’t interested in politics on either side as far as I knew.”

Available information shows Mr. Jahn grew up in Allen, Texas, and had been involved in Boy Scouts.

Noah Jahn also said that his parents owned a rifle and his brother knew how to use it, though he was “not a marksman.”

“He would not be able to make any shots like that,” he said.
