A 211-page Knox County Sheriff’s Office file says 19-year-old Tycen Proper planned an attack tied to the UFC Freedom 250 event and talked about targeting the “evil government,” hit-and-run attacks and data centers.
June 10 became the turning point after Proper’s mother alerted Danville police and sheriff’s deputies; the file says his father also reported online contacts and a planned West Virginia trip for reconnaissance.
131 new photos and seized evidence show Proper spent about $3,000 in graduation money on firearms, ammunition, tactical gear, trauma supplies, camping equipment and food; the AR-15 was bought in January and a shotgun on June 5.
June 11 records show Proper was on a mental-health hold over homicidal ideations, and local authorities notified the FBI and Secret Service before a search warrant was executed at his home.
Proper remains jailed after waiving a detention hearing in U.S. District Court, while the newly released file also documents earlier suicidal ideation in February 2025.
