Overview: The defense of Tyler Robinson has moved to disqualify the Utah County Attorney’s Office from the murder prosecution of Charlie Kirk, arguing an 18-year-old child of a deputy prosecutor attended the UVU event where Kirk was shot. Prosecutors say the student "did not see Charlie get shot" and would not be a witness. Legal experts say courts presume prosecutorial good faith and typically require a clear showing of actual impairment before disqualification. The court will weigh witness testimony — including from the prosecutor and his adult child — and whether any real conflict affected decisions such as the early death-penalty notice.
Prosecutor’s Adult Child Was At Charlie Kirk Shooting — Should Utah County’s Office Be Disqualified?

The prosecution of 22-year-old Tyler Robinson — accused of killing conservative activist Charlie Kirk at a September speaking event at Utah Valley University (UVU) — has moved into a pretrial dispute over whether the Utah County Attorney’s Office should be removed from the case. The defense argues a potential conflict exists because an 18-year-old child of a deputy prosecutor attended the UVU event. The county office denies any conflict, saying the student "did not see Charlie get shot" and "did not see anyone (in the crowd or elsewhere) with a gun."
What the Defense Argues
The defense filed a motion to disqualify the entire office in December, citing Utah’s Code of Judicial Administration and claiming a "concurrent conflict of interest," including a "personal interest of the lawyer." Defense lawyers say the presence of the prosecutor’s adult child at the event could reasonably taint prosecutorial decision-making — including the rapid decision to seek the death penalty.
Prosecution’s Response
The county attorney’s office has rejected the claim. Its court filing notes the 18-year-old would not be called as a witness because their knowledge is "based entirely on hearsay," and argues that witness accounts the defense submitted show the child’s perspective is unnecessary to the case.
Legal Experts Weigh In
Legal scholars and analysts told CNN courts generally presume prosecutorial good faith and require a clear showing of actual impairment before disqualification. Paul Cassell, a University of Utah criminal law professor, said such motions rarely succeed without convincing evidence that fairness is in doubt. CNN legal analyst Joey Jackson emphasized the court must decide whether attorneys are making decisions "predicated upon the merits, the facts, the law, and the circumstances only and that there are no outside influences."

What Will Happen In Court
The hearing will include testimony from Utah County Attorney Jeffrey Gray (who will finish his testimony), the prosecutor in question, the prosecutor’s adult child, and an investigator with the county attorney’s office. The defense has submitted declarations from five witnesses describing chaotic scenes at UVU and estimated roughly 3,000 people attended, with some witnesses describing "pure panic."
Possible Remedies And Practical Issues
If the judge finds a conflict, the most likely remedy is disqualifying the individual with a conflict rather than the entire elected office — an extraordinary step that could effectively upend the results of a county election. If the entire office were barred, prosecutors say the case could be reassigned to a neighboring county or to the Utah Attorney General’s Office, each option carrying political or resource trade-offs.
Death Penalty Timing
The defense also argues the county rushed to file notice of intent to seek the death penalty. Under Utah law prosecutors have 60 days after arraignment to give such notice. The county says filing the notice early is not unusual and that the evidence supports pursuing capital punishment. Robinson’s preliminary hearing is scheduled to begin May 18 and last three days; he has not yet been arraigned and faces charges including aggravated murder, felony use of a firearm, obstruction of justice and witness tampering.
Precedents And Context
Conflict claims are uncommon but not unprecedented. The article notes earlier high-profile disputes — including arguments about recusal in the Luigi Mangione federal case and a potential conflict involving Brian Kohberger’s appointed counsel — where judges weighed whether past relationships or limited representations created disqualifying conflicts.
Next Steps: The judge will evaluate testimony and evidence presented at the hearing to determine whether any actual impairment affected prosecutorial judgment. The outcome will hinge on whether the defense can show specific, demonstrable influence on prosecutorial decisions rather than speculation or emotion.
