The Brief Two Riverside County residents, Bryan Omar Roa and Michael Alan Thomas, face murder conspiracy charges after the FBI dismantled a mass casualty plot targeting the White House. The anti-government conspiracy planned to utilize explosive-laden drones and snipers to assassinate political leaders at UFC Freedom 250, a heavily funded historic fight card held on the White House lawn. While the multi-agency law enforcement operation successfully neutralized the threat before any execution took place, court proceedings are ongoing as investigators work to unseal the broader case files. Two California men are facing federal charges for their alleged involvement in a thwarted anti-government conspiracy to launch a large-scale sniper and drone attack at a UFC event on the White House lawn. What we know: Bryan Omar Roa and Michael Alan Thomas, both residents of Riverside County, were arrested for their alleged roles in the disrupted plot, according to the Knox County Sheriff's Office. Both men have been charged with Conspiracy to Commit Murder and made their initial court appearances on Monday in Riverside. According to a federal criminal complaint, Roa and Thomas were brought to the attention of the FBI by an Ohio co-conspirator, 19-year-old Tycen C. Proper. Proper was interviewed by the FBI on June 11, 2026, after his parents contacted local law enforcement. During that interview, Proper identified Roa and Thomas through their social media accounts, tying them directly to the multi-state plot. Federal investigators recovered screenshots from Proper's Apple iPhone detailing explicit plans shared among a group of approximately 19 individuals using encrypted applications like Signal and SimpleX. The digital evidence included aerial photos and maps of Washington, D.C., and the White House, alongside discussions of where snipers should be positioned and where explosive-laden drones should be launched.
