Attorneys for Tyler Robinson, the man charged in the fatal shooting of conservative activist Charlie Kirk at a Utah event last year, argued this week that Robinson should not face the death penalty because prosecutors have not proved that others present were put at risk — a state law aggravator that would make the crime eligible for capital punishment.
Defense challenges aggravating circumstances
In court filings submitted late Tuesday, Robinson’s lawyers said the evidence fails to show that the gunman endangered patrons at the Sept. 10 gathering at Utah Valley University. The event drew thousands of people, and prosecutors have alleged Robinson acted with political motivation, which could enhance his sentence if proven.
"hit the intended target"
The defense asserted the shooter struck only the person he intended to kill and therefore did not create the broader risk that state law identifies as an aggravating factor. They also disputed assertions that Robinson selected Kirk because of his political views, saying searches of Robinson’s residence and electronic devices produced only a single statement attributed to the defendant — and that alone does not establish motive, the filing said.
Prosecution says evidence is overwhelming
Prosecutors, by contrast, have described the case as supported by what they called overwhelming evidence. During a hearing last month the state presented DNA results tying Robinson to the suspected murder weapon and recounted what it described as apparent confessions by the defendant.
Defense counsel previously questioned the reliability of those items at the hearing but did not offer an alternative explanation for Kirk’s death. The defense did not mention DNA in the most recent filing.
Procedural posture and next steps
Robinson has not entered a plea. He turned himself in the day after the shooting and faces potential sentence enhancements if prosecutors can successfully show he targeted Kirk because of his political views. Prosecutors have until Aug. 18 to file a response to the defense motion.
The defense had earlier sought to remove capital punishment from the case after the prosecution was found in contempt for speaking to the media about the matter; State District Judge Tony Graf rejected that request.

The Associated Press reported that prosecutors have alleged Robinson told a former roommate that he killed Kirk because he "had enough of his hatred." That former roommate, Lance Twiggs, spoke with prosecutors and has been identified in reporting about the case. The state’s filings and court proceedings will determine whether those statements and the physical evidence meet the legal standard for aggravated murder under Utah law.
The case continues to move through pretrial motions as the state and defense spar over the admissibility and sufficiency of evidence that would expose Robinson to the most severe penalties available under state law. The Utah County Attorney’s Office did not immediately respond to requests for comment.
As the legal fight develops, the proceedings raise broader questions about how courts will weigh evidence of motive and public safety in cases where a high-profile political figure was the target.
