Utah woman accused of husband's murder searched for lethal doses of fentanyl and luxury prisons, prosecutors say.

Kouri Richins, a Utah woman accused of poisoning her husband and authoring a children's book on grief, allegedly searched for lethal doses of fentanyl, life insurance payouts, and lie detector tests on her iPhone. Prosecutors argue that the searches indicate a consciousness of guilt and plan to hide evidence. Richins was denied bail and is facing charges of aggravated murder and possession of a controlled substance with intent to distribute. The case may revolve around financial and marital disputes as possible motives.
