Overview
- Two additional suspects were arrested in separate operations — William Lee Spartacus Falkner on June 19 and Jordan W. Rincker on June 21 — bringing the number of publicly charged defendants to seven.
- Prosecutors say the conspirators planned to use explosive-laden drones to force an evacuation of the June 14 UFC Freedom 250 event on the White House South Lawn and then ambush fleeing attendees with prepositioned shooters.
- Agents opened the probe after a June 10 tip from the parents of co-conspirator Tycen C. Proper and identified wider networks by extracting data from Proper’s phone and encrypted Signal and Telegram chats that linked roughly 19–20 participants.
- Searches tied to the arrests recovered multiple firearms, ballistic plates and vests, night-vision gear, a 3D printer and 3D-printed gun parts, and off-grid communications equipment that prosecutors say show efforts to procure and build weapons and drone components.
- Federal prosecutors say the investigation is ongoing, more arrests or charges are possible, and the case is likely to trigger renewed review of security planning for private events held on the White House grounds.
