On the night of March 4, 2022, Eric Richins accepted a Moscow Mule from his wife Kouri in their home in Kamas, Utah. He went to bed. He never woke up.
The medical examiner found fentanyl in his system at five times the lethal dose. Eric was forty-nine years old, a father of three young boys, and according to those who knew him, he had no history of drug use. His death was ruled a homicide. His wife now stands trial for his murder.
The Valentine's Day Warning
Six weeks before that fatal cocktail, something happened on Valentine's Day that would later haunt everyone who dismissed it.
Eric Richins fell severely ill after eating a meal Kouri had purchased for him. He survived the night—barely. And then he told people something that would only make sense after his death: he believed his wife had tried to poison him.
Family and friends attributed his illness to an allergic reaction. They had no framework for the alternative. Who suspects their spouse's spouse of attempted murder?
Prosecutors now point to that Valentine's Day incident as the first attempt. A receipt from February 14, 2022, became a key piece of evidence. The meal. The sudden illness. The husband's own words of warning. All of it documented, all of it ignored until it was too late.
Following the Fentanyl
The prosecution's case rests on a straightforward question: how did a suburban real estate agent in Park City obtain enough fentanyl to kill her husband?
The answer came from Carmen Lauber, the Richins family housekeeper, who took the stand and admitted to purchasing fentanyl for Kouri—not once, but multiple times before Eric's death.
Lauber's testimony placed her at significant legal risk. She admitted to drug trafficking in open court. Her willingness to testify against her former employer speaks to either the weight of evidence or the weight of conscience. Possibly both.
Fentanyl is a synthetic opioid approximately one hundred times more potent than morphine. A lethal dose can be measured in micrograms—invisible to the naked eye, impossible to taste. The amount found in Eric's blood was not consistent with recreational use or accidental exposure. The massive dosage, prosecutors argue, could only mean deliberate introduction.
The Financial Pressure
Behind the facade of a successful couple building a life in Utah's mountain country, prosecutors allege Kouri Richins was drowning.
Her realty business was failing. Debt had accumulated over several years. And she had taken out insurance policies on her husband's life totaling more than two million dollars—a sum that would have eliminated her financial problems entirely.
Bank records, business ledgers, and loan documents all became part of the prosecution's case, painting a picture of mounting desperation. The alleged motive follows a grim pattern seen in other poisoning cases: financial pressure, insurance money, and a spouse who stood between the defendant and solvency.
After Eric's Death
The hours and days following Eric's death revealed behavior prosecutors found telling.
According to testimony, Kouri texted about obtaining the death certificate before Eric's sister could get it. She photographed the document and shared it with others, noting there was "a trace of fentanyl"—a curious detail to highlight, prosecutors suggested, for someone who claimed to know nothing about how her husband died.
Then came the book. In the months after Eric's death, while under investigation for his murder, Kouri self-published a children's book about grief. Written for her three sons. About losing their father. Prosecutors would later point to this as part of a pattern—a mother crafting a public narrative while allegedly concealing the truth.
Text messages between Kouri and a boyfriend she began seeing after Eric's death provided additional context. The digital trail has become central to the prosecution's case.
What the Evidence Asks of Us
Eric Richins told people he thought his wife was trying to poison him. They didn't act on his warnings until he was dead.
This case raises uncomfortable questions that extend beyond one courtroom in Summit County. What do we do when someone tells us they think they're being harmed? How seriously do we take warnings that seem impossible? Poisoning by intimate partners is rare—but not unheard of. When someone expresses fear of their spouse, documenting it and reporting it to professionals could save a life.
The trial, which began February 10, 2026, is scheduled to conclude on March 27. Twelve citizens will weigh the housekeeper's testimony, the toxicology reports, the text messages, the financial records. They will decide whether Kouri Richins murdered her husband.
She has pleaded not guilty to all charges, including aggravated murder, attempted aggravated murder for the Valentine's Day incident, insurance fraud, and forgery. If convicted of aggravated murder in Utah, she faces life in prison without the possibility of parole.
Whatever that verdict, Eric Richins' three sons have already lost their father. They will carry this case with them for the rest of their lives. The Moscow Mule—traditionally vodka, ginger beer, and lime in a copper mug—has become this case's shorthand. A symbol of the ordinary turned sinister. A husband accepting a drink from his wife. The most intimate form of trust, allegedly violated.
