Kouri Richins, who authored a children's book about grief, was found guilty of murdering her husband, Eric Richins, in March 2022, by mixing a lethal dose of fentanyl into his drink. Prosecutors revealed that Richins was facing financial difficulties and had initiated life insurance policies worth about $2m on her husband without his knowledge, suggesting she had premeditated the crime to secure his wealthy estate valued at over $4m.

The investigation uncovered troubling details from Richins's internet search history, which included queries about lethal doses of fentanyl and conditions in luxury prisons for the wealthy. This information highlighted the extent of her planning and the cold-heartedness of her actions, raising questions about mental health and possible motivations tied to financial strain and relationship issues.

The case has attracted significant media attention, emphasizing issues related to domestic violence, the complexities of marital relationships, and the lengths to which individuals may go when influenced by financial desperation. The conviction serves as a stark reminder of the darker sides of human behavior and the impacts of greed and betrayal within intimate partnerships.
