A mum-of-three who wrote a children's book about grief after her husband's death has now been charged with his murder.
Author Kouri Richins is accused of poisoning her husband Eric Richins with a lethal dose of fentanyl at their home in Kamas, Utah.
Prosecutors allege that Richins called authorities in the middle of the night in March 2022 to report that her husband was "cold to the touch."
