The U.S. Department of Justice on Monday announced the arrests of two more men in connection with an alleged plot to attack government officials and attendees at the UFC Freedom 250 event held at the White House on June 14.
The arrests of William Lee Spartacus Falkner in Washington state and Jordan W. Rincker, 28, of St. Joseph, Missouri, bring the total number of individuals charged in the case to seven. Both men face charges of conspiracy to commit murder.
According to the DOJ, Falkner allegedly conspired with others to procure and fly explosive-laden drones as part of the plot. Communications indicated he had experience manufacturing and piloting drones and discussed loading explosives onto them while configuring and flying them for maximum destructive impact.
The plan reportedly involved using drones to attack one side of the event to force attendees, including government officials, to exit from the other side, where co-conspirators would shoot them with sniper rifles and other weapons. Falkner and another individual discussed a “Work trip” prior to the UFC event and later communicated that the “trip” was cancelled following the arrests of other co-conspirators, prosecutors said.
Rincker allegedly possessed weapons and agreed to produce drone parts for use in the plot. He also allegedly accepted $1,200 in cash from co-conspirator Abraham Hermosillo Alvarez to disperse payments to other participants and sent $100 via Cash App to Bryan Omar Roa for gas money to drive from California to Washington, D.C., to pick up the “drone operator.”
In addition, Rincker gave a 12-gauge pump-action shotgun to Alvarez during an in-person meeting in Omaha in exchange for items including an ammunition-filled bandolier, ballistic plate, face shield, 3D printer and filament, night vision goggles, binoculars, a “wire checker,” and a minicomputer. A search of Rincker’s home and storage unit recovered multiple firearms (including a FN Reflex 9mm pistol, FMK AR1 eXtreme multi-caliber rifle, Remington 597 .22 LR rifle, and a 3D-printed Glock-style pistol), ammunition, tactical gear such as a gas mask, night vision goggles, thermal imaging scope, plate carrier, ballistic plates, a 3D printer, and an off-grid mesh network device for secure communications without cellular or internet service, prosecutors outlined in a press release.
“These arrests are the latest result of the FBI, teaming up with our great partners, to identify and apprehend those who allegedly wanted to attack the UFC Freedom 250 event — a threat this FBI and our partners prevented,” FBI Director Kash Patel said following the arrests.
“In just over a week we have executed a multi-state operation that could not have been possible without our Justice Department prosecutors, the FBI’s Counterterrorism Division, Secret Service, and our state and local law enforcement partners to once again stop a potentially deadly plot before alleged criminals could act. This collective resolve demonstrates to anyone who threatens the lives of American citizens — this FBI and our partners will find you no matter where you hide, and you will face justice.”
The latest arrests follow an initial sweep on June 16, when five men were charged in the same alleged conspiracy. Tycen C. Proper, 19, of Danville, Ohio; Bryan Omar Roa, 24, of Calimesa, California; Michael Alan Thomas, 32, of Pinon Hills, California; Daniel K. Eskridge, 32, of Kidder, Missouri; and Abraham Hermosillo Alvarez, 31, of Omaha, Nebraska are all facing conspiracy to commit murder charges.
The group allegedly planned to attack government officials and attendees at the UFC Freedom 250 event on the White House South Lawn on June 14. The scheme involved explosive-laden drones to force evacuations into sniper fire on high-value targets, including members of Congress. Planning began in group chats around March 2026 and moved to encrypted messaging.
Abraham Hermosillo Alvarez, identified as the ringleader using the name “Shepherd,” allegedly directed planning, recruitment, and operations from Nebraska. He provided maps, positioning instructions, and drone guidance, and coordinated logistics across states. Alvarez is a Mexican national who entered the U.S. on a B-2 tourist visa in 2001 as a child, overstayed, and later received DACA status.
