Kouri Richins, the 36-year-old Kamas, Utah woman convicted of poisoning her husband and later sentenced to life in prison, has filed a motion seeking a new trial in Summit County’s 3rd District Court, her defense attorneys announced Tuesday.
Richins was convicted in March of killing her husband, Eric Richins, who died on March 4, 2022. She was sentenced in May to life without the possibility of parole. Her arrest came more than a year after Eric’s death — a span during which Richins had hired a ghostwriter to publish a children’s book about coping with grief, a detail that drew widespread public attention during the case.
Defense Claims Judge Favored Prosecution
The motion for a new trial rests on two primary claims: that the presiding judge demonstrated bias in favor of the state, and that prosecutors were improperly allowed to introduce evidence of Richins’ alleged financial crimes spanning several years.
Defense attorneys argue the judge “repeatedly interrupted” courtroom proceedings in ways that made defense counsel appear to be mishandling witnesses, undermining Richins’ ability to receive a fair trial. The filing characterizes this judicial conduct as a pattern, not isolated incidents, and contends it created an unfair atmosphere before the jury.
The defense is also requesting a new evidentiary hearing to address what it characterizes as improper introduction of financial crime evidence. Attorneys argue that allowing prosecutors to present that material went beyond the scope of what was relevant to the murder charge and substantially prejudiced Richins in the eyes of jurors.
Murdaugh Case Cited as Legal Precedent
In a notable legal comparison, the defense motion draws a parallel between Richins’ case and the high-profile Alex Murdaugh prosecution in South Carolina. The South Carolina Supreme Court overturned Murdaugh’s murder convictions in May, finding in part that improper financial crime evidence had been admitted at trial and likely influenced the jury’s verdict.
Richins’ attorneys appear to be arguing that the same category of error occurred in her trial — that financial misconduct evidence, while potentially inflammatory, was not directly tied to the murder charge and should not have been placed before the jury.
The Murdaugh precedent carries weight in that it reflects an appellate court’s willingness to overturn even a high-profile murder conviction when evidentiary procedures were not properly followed. Whether a Utah district court will find the comparison compelling remains to be seen.
Summit County prosecutors have not yet publicly responded to the motion, and no hearing date has been announced.
Richins’ case drew national media coverage partly because of the unusual circumstances surrounding Eric’s death and the children’s grief book. Prosecutors argued that Kouri had a financial motive, having allegedly forged documents related to her husband’s estate and taken out large loans using his identity before and after his death.
For readers following other high-profile Southeast Idaho murder cases, the Richins motion underscores a broader legal reality: conviction does not necessarily end a criminal proceeding. Post-trial motions and eventual appeals can extend cases for years, particularly when defense attorneys identify arguable procedural grounds.
Idaho courts have seen similar post-conviction litigation in cases involving alleged evidentiary overreach, and rulings on competency and evidence admissibility have at times significantly altered the trajectory of criminal proceedings in the region.
What Comes Next
The motion for a new trial now moves through Summit County’s 3rd District Court, where a judge will determine whether to grant a new evidentiary hearing. If the court agrees that judicial bias or improper evidence admission occurred, a new trial could be ordered — though that outcome would require a significant legal finding. If the motion is denied, Richins’ attorneys are likely to pursue a formal appeal through the Utah Court of Appeals or the Utah Supreme Court. Given the life-without-parole sentence and the direct citation of the Murdaugh precedent, this case is almost certain to continue through the appellate process for some time before reaching any final resolution.
