Lawyers for the man charged with killing conservative commentator Charlie Kirk at a Utah university event are fighting to remove the death penalty from the case, contending their client hit only his "intended target" and posed no risk to the thousands of other attendees.
Tyler Robinson's defense attorneys filed a 41-page brief this week arguing that Utah prosecutors have failed to prove the single aggravating factor required to pursue a capital sentence: that Robinson knowingly created a grave risk of death to people beyond Kirk. The filing, submitted to the Utah County Attorney's Office, claims the evidence shows the bullet "traveled above, not through, the crowd" and that no bystander was ever in the line of fire. The Hill first reported on the defense filing.
Robinson stands accused of shooting Kirk during a Turning Point USA event at Utah Valley University last year. Prosecutors charged him with aggravated murder, a capital felony under Utah law, alleging he posed "a great risk of death" to others in the crowd of several thousand. Under Utah Code Title 76, Chapter 3, Section 207, at least one statutory aggravating factor must be established for an aggravated murder charge to stand. Those factors include prior violent crime convictions or the killing of a minor. Prosecutors chose to hang their capital case on the risk Robinson allegedly posed to bystanders.
The defense brief attacks that theory head-on. Robinson's lawyers argue that only a single shot was fired, that the bullet struck Kirk alone, and that the trajectory from the rooftop where Robinson allegedly positioned himself sent the round above the crowd on a downward path. Fox News reported that the suspected weapon, a.30-06 bolt-action Mauser rifle, described as Robinson's grandfather's, was recovered with one spent casing and three unfired rounds.
The defense filing puts it plainly: "The only evidence presented supports that the bullets traveled above, not through, the crowd." Robinson's attorneys also point to communications between Robinson and his roommate and romantic partner, Lance Twiggs, arguing there was "no mention of any threat or intended harm to any other individual(s)."
Prosecutors see the same evidence differently. They contend that Robinson loaded his rifle with four rounds, which showed he anticipated the possibility of missing Kirk, "thereby putting others in danger," AP News reported. The state also argued that reassembling a disassembled rifle could affect accuracy, further increasing the risk to the crowd.
Fox News contributor and criminal defense attorney Donna Rotunno pushed back on the defense's framing, saying the preliminary hearing evidence already established the danger:
"The evidence in the preliminary hearing has already proven that there were many people there... They didn't need somebody specifically to get on the witness stand and say there were all these people in danger."
Robinson has not yet entered a plea. Utah District Judge Tony Graf has scheduled a hearing for September 1, where the court is expected to rule on whether the case proceeds to trial with the death penalty still in play. A previous ruling in the case kept capital punishment on the table over earlier defense objections.
The question of why Robinson allegedly targeted Kirk is itself bitterly contested. Prosecutors have alleged from the start that Kirk was selected because of his political beliefs. They cite messages Robinson allegedly sent to Twiggs, including one that read: "had enough of his hatred. Some hate can't be negotiated out."
Robinson's defense team argues that language is far too vague to establish a political motive. The filing contends the reference to "hatred" does not point to any specific political position Kirk held. Defense attorneys wrote that the circumstances "are not sufficient to establish, even by probable cause which if any political expression of Mr. Kirk motivated Mr. Robinson to select Mr. Kirk for an act of violence."
But other evidence in the record paints a sharper picture. Breitbart reported that Robinson allegedly used his grandfather's rifle to shoot Kirk in the neck from atop a building during the event. And the messages prosecutors cite go beyond the single line the defense wants to isolate. Robinson allegedly wrote to Twiggs: "I had the opportunity to take out Charlie Kirk and I took it." He also reportedly left a note stating he had "the opportunity to take out Charlie Kirk, and I'm going to take it," citing Kirk's alleged "hatred" as his reason.
Robinson's bullets were pre-engraved with political messages, including "Hey fascist, catch," National Review reported, based on evidence presented at a preliminary hearing. A family member told investigators that Robinson had discussed Kirk's upcoming visit to Utah before the shooting, focusing on "why they didn't like him and the viewpoints that he had," according to Utah Governor Spencer Cox.
The defense's argument that no political motive has been established is a hard sell when the accused allegedly carved ideological taunts into his ammunition before firing.
Twiggs, Robinson's roommate and romantic partner, has become a central figure in the prosecution's case. Twiggs, who identifies as a transgender woman, is cooperating with authorities and testified at Robinson's preliminary hearing. According to Twiggs's testimony, Robinson confessed to the killing the day after it happened.
Twiggs told investigators Robinson broke down after the shooting:
"He started crying a little bit and said he wishes he hadn't done it and then kept going around and just doing stuff, I think to keep himself busy or distracted."
Robinson also reportedly confessed to his father, who held him until police arrived. The Washington Free Beacon reported that Robinson was registered as a nonpartisan voter in Utah, though Governor Cox stated publicly that investigators found Robinson was "deeply indoctrinated with leftist ideology."
The courtroom proceedings have not been without controversy. The case has drawn intense national attention, and the legal maneuvering on both sides reflects the stakes involved, not just for Robinson, but for the broader question of how the justice system treats politically motivated violence against public figures.
Cox's characterization of Robinson's ideology drew sharp responses from some who initially tried to cast Robinson as a right-wing figure. Public records and investigative findings contradicted that framing. The governor's assessment, that Robinson was motivated by leftist ideology, aligns with the messages, the engraved ammunition, and the targeting of one of the most prominent young conservative voices in the country.
The killing of Charlie Kirk sent shockwaves through conservative circles. Vice President JD Vance later revealed that Kirk's death had a profound personal impact on his family. And the federal government has since moved to confront the threat of politically motivated violence more directly, with Secretary of State Marco Rubio announcing new far-left terrorist designations and calling political violence "a unique evil."
Robinson's defense team did not respond to The Hill's request for comment. The prosecution has not yet publicly responded to the Tuesday filing. Both sides will present their arguments before Judge Graf on September 1.
The defense's 41-page brief amounts to a bet that the court will read the physical evidence narrowly, one shot, one target, one spent casing, and conclude that no bystander faced mortal danger. Prosecutors will likely counter that a man who climbed atop a building with a loaded rifle and fired into a crowd of thousands created exactly the kind of risk Utah's aggravated murder statute was written to address, regardless of how many people the bullet actually struck.
If the court agrees with the defense, the death penalty comes off the table and the case proceeds as a standard murder prosecution. If the court sides with prosecutors, Robinson faces a potential capital trial for a killing that investigators say was driven by ideological hatred of a man whose only offense was speaking his mind.
A man engraved political slogans on his bullets, climbed a rooftop, and shot a conservative commentator in the neck in front of thousands. His lawyers now argue that because he only hit the person he meant to hit, the state should go easy on him. The court will decide whether Utah law sees it that way, but the rest of us already know what we're looking at.
