A Utah woman has been convicted of aggravated murder after poisoning her husband with fentanyl and then self-publishing a children’s book about coping with grief. Jurors on Monday also found Kouri Richins guilty of fraudulently claiming insurance benefits after the death of Eric Richins in March 2022 at their home outside the ski town of Park City. Prosecutors say Kouri Richins slipped five times the lethal dose of the synthetic opioid into a cocktail that he drank. After her husband’s death, Richins self-published a children’s book about grief to help her sons and other kids cope with the loss of a parent.
