PROVO, Utah (AP) — Prosecutors are preparing to file a capital murder charge Tuesday against Tyler Robinson, a Utah man accused of assassinating conservative activist Charlie Kirk. Authorities state that Robinson, 22, may have been radicalized online and held extremist views.

Robinson's alleged crimes came to light after he was arrested last week for the shooting that occurred during Kirk's appearance at Utah Valley University, where he was known for spirited debates. Evidence collected includes a rifle with engravings linked to anti-fascist messages found after the incident.

The most severe charge proposed against Robinson is aggravated murder, which could subject him to the death penalty. Following the charges, a virtual court hearing is scheduled for Robinson, who has been held without bail and has not been confirmed to have legal representation.

Although Robinson has reportedly not cooperated with investigators, his friends and family have communicated with authorities. Utah Governor Spencer Cox noted concerns about Robinson's ideological shift towards leftist views and his internet habits, which allegedly included the darker aspects of online culture.

FBI Director Kash Patel revealed links between Robinson and DNA evidence found at the scene, raising questions about the motive for the attack. Prior to the shooting, Robinson expressed intentions to target Kirk in writing.

As investigations proceed, public interest in the political implications of Kirk's assassination has grown, with discussions about the broader issues of political violence and divided ideologies in America. The incident has prompted responses from both sides, with many analyzing Kirk's controversial views and how they may have influenced the tragedy.
