Utah Author Faces Life in Prison for Fentanyl Murder of Husband
In a case that blends financial greed with a chilling level of deception, Kouri Richins, a 35-year-old Utah author and real estate agent, is awaiting sentencing after being found guilty of murdering her husband, Eric Richins. The case gained notoriety not only for the brutal nature of the crime but for Richins’ decision to publish and promote a children’s book about coping with the death of a father shortly before her arrest in 2023.
- The Crime: Kouri Richins laced her husband’s cocktail with five times the lethal dose of fentanyl in 2022.
- Prior Attempt: Evidence revealed a previous attempt to poison Eric on Valentine’s Day using a fentanyl-laced sandwich.
- Motive: Prosecutors cite millions of dollars in debt, secret life insurance policies, and a plan to start a future with another man.
- Victim Impact: Three sons have provided heartbreaking testimony, stating they feel unsafe if their mother is ever released.
- Legal Stakes: Richins faces several decades to life in prison, with prosecutors urging a sentence of life without parole.
A Calculated Plot of Poison and Deception
The prosecution’s case paints a picture of a woman driven by financial desperation and a desire to escape her marriage. Kouri Richins, who operated a house-flipping business, was reportedly millions of dollars in debt. To secure her financial future, she opened numerous life insurance policies on her husband without his knowledge, falsely believing she would inherit an estate valued at more than $4 million upon his death.
The fatal event occurred in 2022 at the couple’s home near the ski town of Park City. Prosecutors established that Richins laced Eric’s cocktail with a massive overdose of fentanyl. However, this was not her first attempt. Jurors found her guilty of attempted murder for a previous incident on Valentine’s Day, where she allegedly fed her husband a fentanyl-laced sandwich that caused him to black out.
The Heartbreak of Three Sons
Perhaps the most devastating aspect of the trial has been the testimony of the couple’s three sons, who were ages nine, seven, and five at the time of their father’s death. In a memo submitted to Judge Richard Mrazik, the children expressed profound fear and a desire for their mother to remain incarcerated.
The oldest son, now 13, explicitly stated that he does not miss his mother, telling the court, “I’m afraid if she gets out, she will come after me and my brothers, my whole family.” He expressed a fear that she would take them and “not do good things to us, like hurt us.” These fears are compounded by sealed court documents from the Utah division of child and family services, which allege the boy suffered physical and emotional abuse from Richins following his father’s death.
The middle child, now 11, challenged his mother’s version of events regarding the night of the murder. While Richins claimed she slept in his room, the boy recalled the parents’ bedroom being locked with the television blaring inside. He described trying to reach the key with a broom, only to be yelled at by his mother to go away. He told the judge he is deeply saddened that his father cannot be present for milestones such as learning to drive or attending his graduation.
The youngest son, who was in preschool when the murder occurred, described feeling “hateful and ashamed” when people speak of his mother because “she took away my dad.” He stated that he would feel “so scared” if she were released, adding that he would only feel happy and relaxed once she is gone.
Legal Consequences and Pending Charges
Kouri Richins has been convicted of five felonies, including aggravated murder, insurance fraud, and forgery. Under Utah law, the aggravated murder conviction alone carries a potential sentence ranging from 25 years to life in prison, or life without the possibility of parole. While prosecutors have not sought the death penalty, they are urging Judge Mrazik to impose the maximum sentence of life without parole.

The legal battles for Richins are not over. In addition to the murder convictions, she faces more than two dozen separate criminal charges related to financial crimes in a case that has yet to go to trial.
