PROVO, Utah (AP) — Prosecutors are preparing to file a capital murder charge against Tyler Robinson, the 22-year-old man accused of assassinating conservative activist Charlie Kirk, as they uncover evidence linking him to online radicalization. Investigators have discovered a rifle engraved with anti-fascist messages and documents suggesting Robinson discussed targeting Kirk with his close ones.

Robinson, who has been held without bail, is expected to appear in court for a virtual hearing soon, where the gravity of the charges, potentially leading to the death penalty, will be explained. As officials investigate Robinson's connections and motives, Utah Governor Spencer Cox stated that those familiar with him noted a shift in his political leanings over recent years, indicating possible influences from extreme online environments.

FBI officials revealed that DNA evidence has tied Robinson to a weapon found near the shooting scene at Utah Valley University, where Kirk was speaking at the time. Furthermore, it has emerged that Robinson authored a note expressing intent to harm Kirk.

While the investigation continues, questions about motivations linger, particularly regarding Robinson's known connections with transgender individuals and Kirk's outspoken anti-transgender comments. The community is grappling with implications of Kirk's assassination and what it signals for increasing political violence in America.
