A mother-of-three who wrote a book to help children cope with death of a loved one after her husband's sudden death has now been charged with his murder.
Kouri Richins was arrested on Monday in Utah and is accused in charging documents of poisoning her husband with a lethal dose of fentanyl at their home in Kamas, a small mountain town near Park City.
Her husband, Eric Richins, died at the family home in March 2022 of a suspected overdose.
