Utah mother Kouri Richins wrote a children's book about grief after her husband Eric died suddenly in March 2022, but toxicology revealed he had five times a lethal dose of fentanyl in his system. Now on trial for his murder, investigators uncovered a secret affair, severe financial troubles, and deleted text messages linking her to a drug-dealing housekeeper—painting a portrait of a woman who may have killed for money and freedom. Eric Richins died from over five times the lethal dose of street-manufactured fentanyl, yet no fentanyl was ever found in the home despite 10 law enforcement searches.
