Kouri Richins, a 35-year-old Utah author, is scheduled for sentencing Wednesday after being found guilty in March of killing her husband with a lethal dose of fentanyl.

Richins faces several decades to life in prison on five felony convictions, including aggravated murder. Prosecutors alleged she laced her husband's cocktail with five times the lethal dose of fentanyl in 2022.

Ahead of the sentencing hearing in Park City, Utah, Richins' three young sons said they would feel unsafe if their mother was ever released from prison. The children expressed fear about the possibility of her freedom following her conviction.

Richins had previously published a book about grief following her husband's death, before authorities determined she was responsible for his killing. The case drew attention due to the unusual circumstances surrounding the publication of the grief-themed book.

The sentencing hearing will determine how many years Richins will spend behind bars for the murder conviction and related charges.
