The FBI has revealed a chilling new detail in the assassination of conservative activist Charlie Kirk: the bullets used in the shooting bore engraved messages, adding a disturbing layer to an already explosive case.

Kirk, 31, founder of Turning Point USA, was fatally shot on September 10 while speaking at Utah Valley University. The event, attended by nearly 3,000 people, ended in chaos after a single shot struck him in the neck.

Investigators recovered a .30 caliber bolt-action rifle abandoned in a wooded area near campus. Wrapped in a towel, the weapon contained a spent cartridge and three unused rounds—each engraved with ideological inscriptions. While the FBI hasn’t released the exact wording, sources say the messages reference themes associated with transgender and antifascist movements.

Surveillance footage tracked the suspect, described as a college-aged male wearing black clothing and aviator sunglasses, entering the Losee Center and climbing to its roof before fleeing post-attack. Authorities have withheld the footage pending further investigation.

Forensic teams are analyzing fingerprints, footwear impressions, and the bullets’ markings to determine if the engravings were hand-carved or machine-etched—potentially revealing premeditation or network affiliations.

Kirk’s final words, moments before the shot, referenced mass shootings and gang violence. The assassination has drawn bipartisan condemnation and remains one of the most politically charged killings in recent memory.
