Kouri Richins wrote a children's book on grief after her husband died. Now she's charged with his murder.

After her husband died last year, she wrote a children's book on grief. Now she's 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. According to a probable cause statement, the victims "told a friend that he thought his wife was trying to poison him," CBS affiliate KUTV reported.

Prosecutors allege that Richins called authorities in the middle of the night in March 2022 to report that her husband, Eric Richins, was "cold to the touch." The mother of three told officers that she had made her husband a mixed vodka drink to celebrate him selling a home and then went to soothe one of their children to sleep in their bedroom. She later returned and upon finding her husband unresponsive, called 911.
