PROVO, Utah (AP) — Prosecutors are preparing to file a capital murder charge against 22-year-old Tyler Robinson, who is suspected in the assassination of Charlie Kirk, a conservative activist, and prominent commentator. Court proceedings are set for Tuesday as investigators gather evidence linking Robinson to the shooting that took place during Kirk's appearance at Utah Valley University.

Robinson was arrested shortly after the incident on Wednesday, where Kirk was engaging with students on topics including gun violence and political disagreement. Evidence collected includes a rifle and ammunition adorned with anti-fascist messaging. Authorities are considering aggravated murder charges that could potentially lead to a death penalty sentence.

Investigators are working to uncover Robinson's motives amid indications of a radical ideological shift in his beliefs, as revealed by friends and family. Utah Governor Spencer Cox's comments suggest Robinson may have aligned with leftist views and engaged with radical online communities.

Moreover, DNA evidence has purportedly linked Robinson to items found at the shooting scene, intensifying scrutiny over his actions leading up to the assassination. His family stated that Robinson exhibited troubling behavior prior to the attack, raising critical questions about political violence and societal divisions in the U.S. following Kirk’s controversial stances on issues such as gender and race.

As public dialogues evolve and pressure mounts for accountability, some conservative groups are calling for the ostracism of Kirk's critics, emphasizing an ongoing debate on the implications of political discourse in current societal contexts.
