PARK CITY, Utah (AP) — A Utah mother who published a children’s book about grief after the death of her husband will serve a life sentence without the possibility of parole for his murder, a judge ruled Wednesday.

Kouri Richins was convicted in March of aggravated murder for lacing her husband Eric Richins’ cocktail with five times the lethal dose of fentanyl at their home near Park City in 2022. A jury also found her guilty of four other felonies, including insurance fraud, forgery and attempted murder for trying to poison her husband weeks earlier on Valentine’s Day with a fentanyl-laced sandwich.

Prosecutors said Richins, a 35-year-old real estate agent with a house-flipping business, was millions in debt and planning a future with another man. She had opened numerous life insurance policies on her husband Eric Richins without his knowledge and falsely believed she would inherit his estate worth more than $4 million after he died.

Judge Richard Mrazik handed down the sentence on the day that Eric Richins would have turned 44.

The prosecution had urged Mrazik to impose a life sentence without the possibility of parole, saying Richins’ three sons “should never worry that they may one day encounter her.” The boys also said in a memo to the judge that they would feel unsafe if their mother was ever released from prison.
