The defense for 23-year-old Tyler Robinson asked a judge Friday to prevent prosecutors from seeking the death penalty, arguing recent public comments by the prosecution about a recovered bullet fragment have prejudiced the case. The dispute centers on how media statements about preliminary ballistics results could shape public perception and the pool of potential jurors ahead of a crucial evidentiary hearing.
Robinson is charged with aggravated murder in the Sept. 10 shooting of conservative activist Aaron Kirk, who was struck in the neck while speaking to a large crowd at Utah Valley University. He has not yet entered a plea.
Defense attorneys say prosecutors went beyond permissible bounds by speaking to reporters about forensic findings tied to a small metal fragment recovered from Kirk’s body. That commentary followed reporting of a federal lab’s preliminary conclusion that the fragment did not match the rifle investigators believe fired the fatal shot — a development defense lawyers say was presented to the public as exculpatory without appropriate context.

Prosecutors counter that their communications were limited and necessary to correct what they described as misleading media coverage about ballistics testing. Deputy Utah County Attorney Christopher Ballard told the court his remarks addressed general limits of ballistics science rather than contest-specific facts, and were aimed at countering misinformation that he said risked undue prejudice.
Defense counsel Richard Novak disputed that account, telling the judge the statements were targeted and intended to shape public opinion about the strength of the case. Novak urged the judge to impose a remedy that would prevent the state from seeking the death penalty, saying the prosecution’s conduct had undermined fairness.
State District Judge Tony Graf said he will rule on the contempt allegation on June 22. The judge earlier rejected a defense bid to pause proceedings while an appeal is pending over his decision to allow cameras in the courtroom.
A key procedural milestone is scheduled for July 6, when prosecutors must show there is sufficient evidence to proceed to trial. That hearing will be the most significant public presentation of evidence so far in the case, which until now has been dominated by pretrial disputes.
What the competing claims hinge on is how the forensic findings have been characterized publicly and what additional testing remains to be done. In court filings the defense highlighted that a federal laboratory did not conclusively match the fragment to the rifle investigators have focused on — a finding described as preliminary and subject to further analysis by authorities.
At the same time, investigators say physical evidence links Robinson to the firearm associated with the killing:
- DNA consistent with Robinson’s on the rifle’s trigger
- The fired cartridge casing recovered at the scene
- Two unfired cartridges found with the weapon
- A towel used to wrap the rifle
Those items form the core of the prosecution’s contention that the state has a provable case. Media attention — including headlines suggesting the fragment “did not match” the rifle — prompted both sides to argue about how preliminary forensic information should be communicated outside courtrooms.
Ballard argued in filings that lawyers have a responsibility to correct inaccurate or misleading public reports and that discussing the limits of forensic matching was appropriate. Novak, meanwhile, maintained the comments were an attempt to sway potential jurors.
The judge’s upcoming decisions on the contempt matter and on whether to allow the death penalty to remain an option will shape the next phase of litigation. If Graf finds prosecutorial conduct crossed the line, it could lead to sanctions — though the court has not yet indicated what remedy, if any, it will impose.
As the case moves toward the July hearing, the dispute over off-the-record commentary underscores a broader challenge in high-profile prosecutions: balancing transparency and the public’s right to information with the need to preserve an impartial legal process.
