Federal authorities have identified Abraham Hermosillo Alvarez as the alleged ringleader of a failed terror plot targeting the UFC Freedom 250 event held on White House grounds. According to Department of Homeland Security (DHS) filings, Alvarez entered the United States on a B-2 visitor visa in December 2001 but remained beyond his visa expiration, later overstaying his status for over two decades.
DHS reports Alvarez was granted Deferred Action for Childhood Arrivals (DACA) protection under the Obama administration in 2014 before being arrested by federal agents on June 14, 2026, in Omaha, Nebraska. The same day, the UFC Freedom 250 event took place at White House grounds. ICE has issued a detainer for Alvarez, and authorities state he used the alias “Shepherd” within encrypted communication networks planning the attack.
Federal prosecutors allege Alvarez directed the operation, including providing specific coordinates for a safe zone at an old church in Nebraska, mapping drone launch points, assigning sniper positions, and coordinating routes for high-profile targets such as President Trump, Vice President JD Vance, Benjamin Netanyahu, and Elon Musk. The plot reportedly involved explosive drones to force evacuations followed by sniper attacks on fleeing attendees.
The DOJ has charged five defendants—Tycen Proper, Bryan Omar Roa, Michael Alan Thomas, Daniel Eskridge, and Alvarez—with conspiring to carry out a mass-casualty attack targeting U.S. officials and event participants. Federal records detail encrypted communications, firearms, ammunition, tactical gear, jurisdictional searches across multiple states, and evidence of role-specific planning for the operation.
DHS emphasized that Alvarez’s immigration history—overstaying his visa in 2001 and receiving DACA in 2014—adds significant political weight to the case. Authorities note he was identified as a foreign national in court records prior to DHS providing his Mexican nationality details. Federal officials state the alleged plot represents a coordinated effort to target individuals within a high-security White House event, a scenario treated by federal agencies as a critical national security risk given recent assassination attempts and threats against U.S. leadership.
The DOJ has identified 23 individuals connected to the terror-planning network, though only five have been formally charged as of late June. The FBI confirmed Alvarez’s role in directing operational details through encrypted channels, including specific instructions for evacuation routes and sniper deployment. All defendants remain presumed innocent pending judicial determination.
