Children's Book Author Sentenced to Life for Poisoning Husband

The intersection of children’s literature and true crime just took a deeply unsettling turn. Kouri Richins, a Utah mother who authored a grief-focused children’s book, learned her fate on Wednesday when Judge Richard Mrazik handed down a life sentence without parole for the murder of her husband, Eric Richins.

The case reads like a plot twist nobody saw coming. Kouri was convicted of lacing Eric’s drink with five times the lethal dose of fentanyl in March 2022. But that wasn’t her only attempt—prosecutors presented evidence that she’d tried to kill him on Valentine’s Day 2022 with a fentanyl-laced sandwich. The Utah jury also found her guilty of insurance fraud and forgery, bolstering the prosecution’s theory that Kouri was drowning in millions of dollars in debt and had another relationship waiting in the wings.

What makes this case particularly haunting is the timing and the irony. Kouri was arrested in 2023 while actively promoting her children’s book about a boy coping with his father’s death. Three sons—aged 9, 7, and 5 at the time of Eric’s death—were left without their father. During her sentencing Wednesday, Kouri told her sons from the courtroom that they’d been influenced into believing she killed their father, calling the notion completely wrong and an absolute lie. She’s maintained her innocence throughout, even as the evidence mounted against her.

Judge Mrazik’s words during sentencing were unsparing: A person convicted of those crimes is simply too dangerous to ever be free. The timing added another layer of darkness to the proceedings—May 13 would have been Eric’s 44th birthday. Life without parole means Kouri will spend the rest of her life behind bars, watching from prison as her sons grow up without either parent fully present in their lives.
