FBI Arrests 5 in Alleged White House UFC Terror Plot, Including 19-Year-Old Ohio Suspect

Q: What warning signs of extremism led a family to report their 19-year-old son to the FBI?

The family appears to have acted after seeing a cluster of warning signs: rapid weapons buying, tactical preparations, extremist rhetoric, and secretive coordination with people online. According to court filings and reporting, relatives in Knox County told police and the FBI that Tycen Proper had spent thousands of dollars of graduation money on firearms, ammunition, body armor, ballistic plates, magazines, camping supplies, and other tactical gear. They were also concerned that he had quit his job and was preparing to leave town for what he described as a mission or meet-up tied to the White House UFC event weekend. His family also said he was spending much of his time communicating with an online group that voiced ultra-religious and anti-government grievances. Investigators later said those chats involved discussions of “recons,” weapons, drones, and other pre-operational planning. Family members reported that Proper had made sympathetic comments about Adolf Hitler, which added to their alarm. Another major red flag was his deteriorating mental state. Additional reporting says he was hospitalized on June 10 with homicidal ideations, the same day the FBI learned of the alleged plot. Taken together, the warning signs were not a single statement or purchase but an escalating pattern: stockpiling weapons and protective gear, planning travel with online associates, extremist and pro-Hitler comments, anti-government fixation, and signs of possible intent to commit violence.

Five people are in custody over an alleged plot to attack the UFC Freedom 250 event at the White House, with Knox County, Ohio, resident Tycen Proper, 19, identified in court papers as a leader.
June 10 was when the FBI says it learned of the plan after Proper’s family alerted local police, worried by his firearms, body armor and tactical-gear purchases and his online contacts.
Twenty-three people were allegedly in Signal chats discussing pre-operational plans, and investigators said the group talked about reconnaissance, weapons, drones and violence in Washington.
Federal documents say Proper admitted joining planning discussions and now faces charges including conspiracy against the United States and attempted murder of a federal officer or employee.
June 17 is when Proper is due in federal court, as investigators cite his alleged Hitler-sympathetic remarks and anti-government grievances as part of the case’s broader extremism concerns.
