Overview
- A series of calls from Tycen Proper’s mother to a Knox County chief deputy and dispatch on June 10th prompted a Danville welfare check that started the inquiry.
- Officers transported Proper for an emergency medical admission that evening and local investigators referred the case to the FBI the next day for further review.
- Federal agents say a preliminary search of Proper’s phone found Signal group chats with maps, imagery and proposed sniper and drone locations that showed detailed pre-operational planning.
- Charging documents say Proper admitted to investigators that he and others plotted a coordinated attack during the UFC Freedom 250 event on the White House South Lawn, and five men have been arrested in multiple states.
- Dispatch recordings and bodycam footage released June 18–19 clarify the family’s role in removing firearms and turning them over to police, the use of federal search warrants on seized gear, and ongoing efforts to identify other chat participants.
