FBI Arrests Two More Suspects in Planned Drone and Sniper Attack on Trump White House UFC Event

BLUFArresting seven of roughly twenty identified conspirators has exposed rather than exhausted the network, and additional federal charges are likely before late September 2026.

The FBI arrested William Lee Spartacus Falkner, 21, of Belfair, Washington, on June 19 and Jordan W. Rincker, 28, of St. Joseph, Missouri, on June 21, each charged with conspiracy to commit murder, bringing to seven the total number of federally charged defendants 12. Court filings allege Falkner communicated about his drone manufacturing expertise, loading explosives on drones, and configuring attack runs to drive attendees toward sniper positions; Rincker allegedly distributed $1,200 among co-conspirators and received a 3D printer to produce drone components 123. NPR reported encrypted communications among roughly 20 participants included detailed maps and aerial photographs of the event site, and court documents show one arrested individual told investigators the group's stated goal was government overthrow 14.

Analysis
Thirteen or more identified network participants remain uncharged, and federal authorities will likely announce additional arrests before September 30, 2026. High confidence reflects three converging indicators: the majority of approximately twenty identified participants face no charges, named co-conspirators in Rincker's financial distribution chain remain at large, and the FBI has sustained arrest tempo across five states since the plot's disruption. Falkner and Rincker held load-bearing roles in the attack's execution architecture, meaning their arrests expose rather than exhaust the investigative surface. The Muzi Works off-grid mesh network recovered from Rincker's home operated independently of the group's encrypted chat and remains an unaccounted communications layer.
