Federal authorities have identified the man they say carried out a deadly shooting at a U.S. Immigration and Customs Enforcement (ICE) field office in Dallas on Wednesday. One person was killed and two others were critically wounded before the gunman died of a self-inflicted gunshot wound, authorities said. 

Acting ICE Director Todd Lyons identified the shooter as 29-year-old Joshua Jahn. 

All three of the victims shot were detainees of the facility, federal authorities confirmed.

Jahn legally purchased the 8mm bolt-action rifle used in the shooting last month, officials said.    

Documents show Jahn had ties to North Texas and Oklahoma. According to records, his parents live in Fairview, a town in Collin County, just north of Dallas. Jahn's current address is believed to be in Durant, Oklahoma, records suggest. Residents in a Durant neighborhood describe a line of SWAT teams and police cars driving through the neighborhood on their way to a home that property records connect to Jahn.  

FBI finds note, Google searches for Charlie Kirk shooting, ICE trackers

FBI Director Kash Patel said Jahn's devices had records of him searching for information about ballistics, video of Charlie Kirk being shot and apps that tracked the presence of ICE agents.

"Anti-ICE" messaging was found on shell casings at the scene after shots were fired "indiscriminately" at the facility and at a van in the sallyport, officials said.      

Nancy Larson, the acting U.S. attorney for the Northern District of Texas, said a collection of notes found at Jahn's residence showed an animus towards ICE agents and that he had been planning the attack for some time. 

Patel said agents found a handwritten note that read: "Hopefully this will give ICE agents real terror, to think, 'is there a sniper with AP rounds on that roof?" 

"Further accumulated evidence to this point indicates a high degree of pre-attack planning," Patel said.  

Patel also said that Jahn had downloaded a document from the Dallas County Office of Homeland Security and Emergency Management "containing a list of DHS facilities." 

A similar document to what Patel described is posted on the county website, listing addresses for the ICE facility in Dallas and the U.S. Citizenship and Immigration Services office in Irving. The document appears to be a reference for people who come to the county for citizenship and immigration issues instead of the federal government.

Shooting suspect worked alone, authorities said

Larson said that early Wednesday morning, Jahn was seen driving his car with a long ladder. Officials believe he used the ladder to access the roof of an office building near the Dallas ICE facility, from where he started firing at about 6:30 a.m.   

Another note found at the suspect's residence said, "Yes, it was just me," Larson said.

Larson and Joseph Rothrock, the FBI special agent in charge of the Dallas field office, both said all evidence indicates that Jahn acted alone. 

Larson also said there was no indication that Jahn was a member of any group.

Rothrock said officers from the Dallas Police Department and Dallas County Sheriff's Office found Jahn on the rooftop, dead from a self-inflicted gunshot wound.  

Joshua Jahn's criminal record in Collin County

Court records show Jahn was arrested in 2015 by the Collin County Sheriff's Office and charged with delivering marijuana. 

In 2016, Jahn pleaded guilty to delivery of marijuana between the amounts of a quarter of an ounce and five pounds, according to Collin County court records. He was ordered to pay a $500 fine and was placed on probation for five years.

Community supervision officials later recommended early release, citing his regular reporting and compliance with all conditions. On April 4, 2017, a judge signed off.

Jahn was registered as an independent and last voted in the general election in 2024, according to voter records.

Home in North Texas neighborhood searched 

The suspect grew up in North Texas and had two siblings, according to public records and photos posted to his family's social media accounts.

Neighbors in a residential area of Fairview, a town just north of Dallas where Jahn's family lives, were stunned when law enforcement swarmed their quiet street on Wednesday. Just before noon, local officers blocked off the area to allow FBI agents to enter a home tied to Jahn.

Several agents were seen entering a property and remained inside for several hours, a CBS News Texas reporter witnessed.

Residents described the family as of Norwegian background, with two adult sons who mostly kept to themselves. Neighbors told CBS News Texas they were in disbelief that the deadly shooting might be connected to someone in their community.

Dallas ICE facility shooting leaves 1 detainee dead, 2 wounded

Homeland Security officials said a sniper opened fire Wednesday morning from the roof of a nearby law office into a walled-off courtyard where immigration detainees were signing paperwork before being bused to detention centers.

Dallas Police Chief Daniel Comeaux said officers quickly identified the shooter's location, but by the time they reached him, Jahn had already died by suicide. 

The three gunshot victims, identified only as immigration detainees, were taken to Parkland Hospital. One died from their injuries.
