Federal investigators are reexamining the killing of conservative activist Charlie Kirk, raising doubts about the original lone-gunman theory. Kirk, 31, “was fatally shot in the neck on 10 September 2025 while speaking at an outdoor Turning Point USA event at Utah Valley University.” Authorities initially believed a rooftop sniper using a .30-06 Mauser M 98 rifle carried out the attack.

Police arrested 22-year-old Tyler James Robinson two days later, charging him with aggravated murder. Federal officials now say they are investigating “whether Robinson acted alone or had assistance.” Doorbell-camera footage reportedly shows Robinson fleeing while speaking on a phone, which could indicate possible coordination. Another clip appears to show “a masked figure in tactical gear preparing to fire,” fueling online speculation.

Investigators are also reviewing the behavior of several men standing behind Kirk on stage. Social-media users claimed their gestures looked suspicious, though officials stress “no one on stage has been accused of involvement at this time.” Forensic teams continue examining evidence from the suspected sniper site atop the Losee Center, and ammunition recovered reportedly carried “ideological engravings.”

Digital messages from Robinson’s roommate describe retrieving and hiding the rifle, supporting claims that the attack involved planning. These messages are now part of the expanding investigation.

As multiple theories circulate online, federal officials emphasize their goal is “to determine conclusively whether a second shooter or any accomplices played a role in the attack,” while noting the review is ongoing and no additional suspects have been formally named.
