Federal investigators have widened their probe into the assassination of conservative activist Charlie Kirk, examining whether pro-trans and leftist online groups linked to Tyler Robinson had prior knowledge of the plot. Here’s what has surfaced so far:

Law enforcement sources told The Post that investigators are scrutinising online groups and leftist circles in Utah to determine if they aided Robinson or at least knew he was planning the killing.

A group called Armed Queers SLC, which promoted “queer resistance” events, abruptly took down its Instagram page after Kirk was killed. Their imagery often featured rifles and militant symbolism, drawing fresh attention from investigators.

Robinson’s heavy involvement in gaming platforms like Steam has prompted agents to analyse whether his online communities served as echo chambers, fuelling or normalising violent rhetoric.

Unverified posts are raising red flags: one user wrote on Sept. 9, “Charlie Kirk is coming to my college tomorrow, I hope someone evaporates him,” while another warned, “Be ready… this isn’t a threat, it’s a promise.” Many of these accounts have since been deleted.

Officials are working to establish if Robinson acted alone or was influenced or even encouraged by fringe online groups. Texts, memes, and deleted chats are being combed for evidence of advance knowledge.

Utah Gov. Spencer Cox said Robinson was “deeply indoctrinated with leftist ideology,” suggesting his ties to trans and far-left networks may have shaped his decision to target Kirk, a vocal critic of gender policies.

Despite growing suspicions, the FBI has not confirmed that any group directly assisted Robinson. His transgender roommate, Lance Twiggs, has been “extremely cooperative” with investigators and is not accused of involvement.
