Utah authorities will charge the 22-year-old suspect in conservative commentator Charlie Kirk’s killing, Tyler Robinson, with aggravated murder, felony discharge of a firearm causing serious bodily injury, and obstruction of justice, according to an affidavit released Friday. In Utah, aggravated murder carries a maximum penalty of death.

Robinson had been arrested early Friday morning after a family friend contacted authorities. According to Utah Governor Spencer Cox, Robinson was identified by CCTV on scene at Utah Valley University on the day of the shooting. Cox said that engraved bullets found at the scene featured antifascist inscriptions such as “hey fascist, catch” and references to the Italian Partisan song “Bella Ciao.”

Cox called Kirk’s shooting a “political assassination” and “an attack on the American experiment.” He stated: “[I]n the very act that Charlie championed, of expression, that freedom of expression that is enshrined in our founding documents… having his life taken in that very act, makes it more difficult for people to feel like they can share their ideas, that they can speak freely.”

The affidavit said Robinson was lying prone on a campus rooftop when Kirk was shot, climbing off the roof thereafter. Additionally, it stated that Robinson discussed his dislike of Kirk with a family member before the shooting occurred.

Authorities claimed that Robinson’s actions “created a great risk of death” to others, prompting the use of Utah’s aggravated murder statute. The charge comes after US President Donald Trump told Fox News that he wants Robinson to be executed. Ordinarily, Utah prosecutors must file a notice of intent to seek the death penalty within 60 days of arraignment, or aggravated murder charges will be treated as non-capital.

Previously, officials twice reported that suspects in Kirk’s killing were taken into custody and subsequently released.
