Dallas, Texas — Joshua Jahn, the suspect in the Dallas ICE shooting, continues to be the subject of an ongoing FBI investigation. The FBI’s Dallas field office and FBI Headquarters have been working around the clock, seizing devices, and processing data obtained from his person, residence, and bedroom. This extensive investigation has revealed a troubling series of activities that appear to show a high degree of pre-attack planning and a possible ideological motive behind the shooting that left two detainees dead and another critically injured.

Suspect’s Digital Activity: Ballistics, DHS Facilities, and ICE Agent Tracking

According to FBI sources, Joshua Jahn downloaded a document titled “Dallas County Office of Homeland Security & Emergency Management”, which contained a list of Department of Homeland Security (DHS) facilities. This document could have provided valuable intelligence to the suspect about ICE’s presence in the area and the facilities’ operations.

Jahn’s online activity between September 23 and September 24, 2025 shows multiple searches related to ballistics, including inquiries about armor-piercing rounds (AP rounds), and a search for the “Charlie Kirk Shot Video”—a controversial video that has been linked to radical political ideologies. These searches suggest that Jahn was actively preparing for the violent attack.

Additionally, between August 19 and August 24, 2025, Jahn conducted multiple searches on apps that track the presence of ICE agents, which could indicate his intention to target specific locations where ICE personnel were operating.

Handwritten Notes: A Chilling Message

Among the evidence gathered, investigators found one of Joshua Jahn’s handwritten notes with a chilling message that read, “Hopefully this will give ICE agents real terror, to think, ‘Is there a sniper with AP rounds on that roof?’” This note, recovered during the investigation, underscores the premeditated nature of the attack and suggests that Jahn had planned to use sniper tactics to target ICE agents.

This note, along with other evidence from Jahn’s devices, indicates that the suspect had a clear ideological motive tied to his disdain for ICE and its role in enforcing federal immigration laws.

Pre-Attack Planning and Coordination

FBI officials have noted that the evidence points to significant pre-attack planning. The meticulous searches for ballistics, DHS facility lists, and ICE agent tracking apps suggest that Jahn’s actions were deliberate and carefully coordinated in the days leading up to the attack. The combination of online research, weapon knowledge, and handwritten notes all points to a person who was preparing for violent action against ICE and its officers.

The FBI has not yet confirmed the exact method of how Jahn accessed or obtained this information, but it is clear that his digital and physical actions were linked to the shooting on September 24, 2025.

Sister’s Connection: Kioko Jahn Linked to LGBTQ Community and Controversial Platforms

Adding another layer to the investigation, Kioko Jahn, the sister of Joshua Jahn, has been identified as someone who is reportedly active in the LGBTQ community and OnlyFans platform. Kioko Jahn‘s involvement in the LGBTQ community and on the OnlyFans platform has drawn attention, especially as the investigation delves into the family’s dynamics and any potential influence or connections.

In addition to her online presence, Kioko Jahn has also been linked to prior arrests, though details about these incidents have not been fully disclosed. Investigators are looking into whether Kioko’s activities, particularly her ties to online communities, may have played any role in shaping Joshua Jahn’s actions or mindset.

Ongoing Investigation and Public Appeals for Information

As the investigation into the shooting continues, the FBI is urging anyone with information regarding Joshua Jahn’s activities or background to come forward. The Dallas ICE shooting has raised significant concerns about politically motivated violence, especially when targeted at government agencies like ICE.

The FBI has promised to provide further updates as the investigation progresses and more information becomes available. Investigators are continuing to explore Jahn’s connections, including any potential links to radical groups or individuals with similar ideologies.

In the meantime, authorities are focusing on understanding the full scope of Jahn’s planning, his motivations, and how he came to carry out such a violent act against federal law enforcement officers.

The Ongoing Search for Answers

The FBI’s Dallas field office and FBI HQ are working tirelessly to uncover more details about Joshua Jahn’s planning and the ideological motivations behind the attack. While the investigation into his digital footprint continues to reveal disturbing evidence, investigators are also reaching out to the public for additional clues or information that might shed light on the broader context of the attack.

As the FBI continues its work, the nation watches closely to see if the investigation uncovers more links between the suspect and anti-government or anti-ICE groups that may have influenced his actions. The troubling details of his online activity, combined with the discovery of his handwritten notes, suggest that Joshua Jahn’s attack on the Dallas ICE facility was not just an isolated act of violence but a part of a larger pattern of political radicalization and violence.
