The gunman who killed one and wounded at least two others in a shooting at a U.S. Immigration and Customs Enforcement facility on Wednesday was beset by a history of family legal troubles long before he met his violent end.
Joshua Jahn, 29, who died of a self-inflicted gunshot wound, was the brother of Kioko Jahn, 27, whose records show she was arrested three times since 2017. She has had numerous other entanglements with the law, according to online records reviewed by the NY Post.
The shooter’s sister was first arrested on April 4, 2019, for misdemeanor assault. She pleaded guilty seven months later as part of an unspecified deal, records state.
Three years later, on March 4, 2022, the Fairview native was booked on a marijuana charge, one similar to what Jahn himself was charged with seven years earlier. Her case was dismissed in August 2023.
The very next day, sister Jahn was again handcuffed and brought in but set free under magistrate-set bond conditions, court records show.
Jahn’s brother fired a hellish series of rifle rounds at an ICE detention center in Dallas, killing one illegal immigrant and wounding two others as officers were bringing in a busload for processing. Police surrounded Jahn on a nearby rooftop, where he shot himself in the head with a hunting rifle similar to the one used to kill Charlie Kirk earlier this month.

The gunman was a registered independent voter who voted in the 2020 Democratic primary, according to state voter records. He last cast a ballot in the 2024 election.
At a press conference shortly after the shooting unfolded, an FBI spokesperson confirmed that Jahn had left “ANTI-ICE” scrawled on one of the rifle rounds he planned to fire that day, suggesting his motive was hostile to members of law enforcement.
Not far from the scene, law enforcement discovered a blue Toyota Corolla believed to belong to Jahn, which had a handmade sign affixed to its right rear quarter panel and read “Radioactive fallout from nuclear detonations has passed over these areas more than 2x since 1951.”
The map appeared to be one derived from an original created by Richard Miller, a nuclear researcher who reported on crosscurrents between two nuclear clouds resulting from U.S. testing in the Nevada Desert in the 1950s and 1960s.
Wednesday’s shooting is being investigated as a targeted attack on federal immigration officers, according to Joe Rothrock, special agent in charge of the FBI in Dallas.
“I can confirm at this time that the FBI is investigating this incident as an act of targeted violence,” he said at the press conference, the NY Post reported.
“It is unfortunately just the latest example we’ve seen of targeted violence, to include here in north Texas where back on July 4 we saw a coordinated attack against an immigration center in Alvarado.”
