Kouri Richins has been dubbed the 'Moscow mule killer'.Richins is charged with murder and drug possession. The mom of three later self-published an illustrated book about an angelic father watching over his sons. Prosecutors say that she slipped five times the lethal dose of fentanyl into a Moscow mule cocktail she made for her husband, Eric Richins, amid marital disputes and fights over a multimillion-dollar mansion she ultimately purchased as an investment. It has subsequently emerged that Richins had googled 'luxury prisons for the rich in America' and 'Is naxolone similar to heroin'. It has also been revealed that Richins also searched if police can see deleted texts, if cops can force you to take a lie-detector test, and how long life insurance payouts take. After Eric's death, Kouri wrote a book titled 'Are You With Me?' - a picture book that aspires to help children cope after the death of a loved one.
