FBI: Thomas Crooks Acted Alone in Trump Assassination Attempt

After an unprecedented global investigation, the FBI concluded Thomas Matthew Crooks, 20, acted alone in the July 13, 2024 Butler, Pa., shooting that wounded former President Donald Trump; investigators found no co-conspirators and cite no clear motive.

The FBI described its review of the July 13, 2024 shooting in Butler, Pennsylvania, as one of the most exhaustive domestic probes in recent memory. Bureau investigators, working with federal partners and overseas contacts, interviewed thousands of people, reviewed financial records and purchases, and examined digital footprints to trace any possible support network.

Investigative scope included:

• Cross-border searches of email and social media accounts
• Financial and purchase histories related to weapons and supplies
• Forensic review of video evidence and travel records

News outlets summarized the FBI briefing and the breadth of the effort — see reporting by ABC News and a compiled timeline on Thomas Crooks.

Investigators have not been able to establish a clear motive. Officials reported Crooks had no known history of organized political activism and that his online activity included searches across both major political spectrums. Some details were obscured by privacy tools, including VPN use, which complicated efforts to fully reconstruct intent.

Officials noted that the suspect appeared intellectually capable but possibly affected by undiagnosed psychological or developmental issues.

Authorities recovered an AR-15–style rifle at the rooftop scene. Investigators determined the weapon was obtained through a legal family transfer. Officials also recovered bomb-making materials in Crooks’s vehicle and home and said he carried a remote detonator on his person; there is no evidence these devices were deployed or tied to outside assistance.

Facts reported:

• Eight shots fired from a nearby rooftop using an AR-15–style rifle.
• Bomb-making materials found in vehicle and residence; a remote detonator was recovered.
• Weapon traced to a legal family transfer.

Some House Republicans have alleged the FBI withheld records and “stonewalled” congressional review requests. Representative Pat Fallon and others say they were denied access to certain investigative materials and have called for additional oversight into whether the attack could have been prevented.

“The FBI needs to show transparency,” critics argued, pressing for fuller access to online search histories and other records.

A task force led by Representative Fallon published a report examining security and communications; the full task force report is available from the congressional office here. Media coverage of the allegations includes reporting from KOMO/Komonews and Fox News.

Following the attack, an internal review of Secret Service conduct led to the suspension of six agents while investigators probe whether protocols were followed and whether intelligence-sharing failures contributed to security gaps. The suspensions reflect institutional scrutiny and a broader review of event security planning for high-profile appearances.

Reporting on the suspensions was published by ABC News.

The FBI’s conclusion that Crooks acted alone carries multiple local implications for Walla Walla:

• Public safety and events: Organizers should review rooftop sightlines, perimeter controls and coordination with federal partners when hosting high-profile figures.
• Law enforcement coordination: Joint tabletop exercises and clearer channels for sharing threat information can help mitigate gaps highlighted by the Butler review (task force report).
• Campaign appearances: Local political organizers may face higher costs and stricter requirements for security without curtailing public access.
• Mental health outreach: The case underscores the need for community programs targeting isolated or troubled young adults (CBS News profile).
• Gun-transfer discussion: The legal family transfer that yielded the weapon may prompt local debate about safe storage and transfer practices.

Local leaders can help by offering clear briefings, coordinating with state representatives, and ensuring timely public information to maintain community confidence.

Major outlets that covered the FBI’s findings include ABC News and CBS News. A compiled timeline and source links are available on the Thomas Crooks Wikipedia entry. Certain commentators have emphasized perceived gaps in public disclosure and called for additional congressional review (KOMO/Komonews; Fox News).

Despite the breadth of the probe — including digital records and thousands of interviews — the FBI reported no evidence of outside coordination or instruction. Privacy tools limited visibility into portions of Crooks’s online activity, leaving unanswered questions about intent, planning and whether additional signals were missed.
