Kouri Richins seeks to disqualify murder trial judge in re-trial request

Judge Richard Mrazik, right, talks to Brad Bloodworth, chief prosecutor for Summit County, during the trial of Kouri Richins, a Kamas-area mother accused of fatally poisoning her husband, at the Summit County Justice Center Monday, Feb. 23, 2026.

Third District Judge Richard Mrazik referred Richins' petition to a separate state judge for review July 1.

The judge who sentenced Kouri Richins to life in prison for aggravated murder is asking another judge to step in after her defense team requested his removal June 30.

The 14-page motion asked for the court to vacate her conviction and hold a new trial. They say the judge’s actions created “an appearance of bias” against Richins and in favor of prosecutors throughout the trial.

Mrazik said those allegations of bias present a conflict of interest for the court.

“Given the apparent objective bias discussed, the actual conflict of interest created by allegations of the court’s bias, and the need to ensure due process, disqualification from ruling on this motion is warranted,” he wrote in a case filing.

The presiding judge for the district will now review whether Mrazik was biased.

In March, a jury found the Kamas mother of three guilty of aggravated murder and attempted aggravated murder in the 2022 fentanyl overdose death of her husband, Eric Richins. She was also convicted of insurance fraud and forgery.

Mrazik sentenced her to life in prison without the possibility of parole in May. Her attorneys said the same day they would seek a new trial.

Court papers say allowing the state to rely heavily on Richin’s financial crimes created “substantial undue prejudice” that denied Richins a fair trial.

The document also points to the reversal of Richard Murdaugh’s South Carolina murder conviction as justification for its request. In that case, the state’s Supreme Court found that allowing prosecutors to use evidence related to financial crimes before focusing on the murder was prejudicial.

Murdaugh’s tentatively set for a new trial in April 2027.

Meanwhile, Richins still faces 26 felonies in another case prosecutors filed last June. The charges represent the full scope of her alleged financial misdeeds. It’s unclear whether prosecutors still plan to pursue that case.

This story was corrected to accurately reflect that Judge Richard Mrazik referred Kouri Richins' request to disqualify him to another judge for review. He did not recuse himself from the murder case as a whole.
