A Utah mother convicted of poisoning her husband with fentanyl and then writing a children’s book about grief has been sentenced to life in prison without parole. Kouri Richins, 36, showed no emotion as she received her sentence on what would have been her late husband’s 44th birthday.

Fatal Cocktail and Insurance Scheme

In March 2022, Kouri Richins laced her husband Eric’s Moscow Mule with a fatal dose of fentanyl at their home. Authorities initially believed Eric had accidentally overdosed, but prosecutors later revealed a calculated financial motive. Richins had secretly taken out a $2 million life insurance policy on her husband while facing more than $4 million in personal debt. The scheme unraveled after investigators discovered inconsistencies in her account of events.

Book Promotion Before Arrest

Before her arrest in spring 2023, Richins wrote and promoted a children’s book titled “Are You With Me?” about coping with grief. She appeared on morning talk shows discussing the loss of her husband, presenting herself as a grieving widow helping her children process their father’s death. The book’s publication while under investigation for his murder would later become a central element in the prosecution’s case against her.

Stone-Faced Sentencing

During Wednesday’s sentencing hearing, Richins addressed her three sons, who had testified they would feel unsafe if she were ever released. “I will never be angry at you for your feelings,” she told them from the courtroom, handcuffed and wearing a neon green t-shirt. She accused her late husband’s family of preventing contact with the children, who are now being raised by Eric’s sister and her husband. “You boys are my world. The reason I continue to wake up every day and fight to come home,” Richins said. She was convicted in March 2025 after prosecutors presented evidence of the insurance fraud scheme and fentanyl purchase.

Family Impact and Justice

The case has devastated both families, leaving three young boys without either parent. Eric Richins’ relatives have taken custody of the children, providing stability after years of investigation and trial proceedings. The life sentence without possibility of parole ensures Richins will spend the remainder of her life in prison for the calculated murder. Prosecutors called it a case of financial desperation leading to the ultimate betrayal of marriage and family trust.
