In July 2012, Lorrie’s 36-year-old son, Aaron, was found dead on his couch — and she claims her daughter-in-law, Fawn, murdered him by giving him a marijuana cigarette laced with a poisonous herb. Lorrie says the couple was separated, and she believes Fawn wanted to collect Aaron’s life insurance before the divorce was finalized. Fawn says although her marriage to Aaron was on the rocks, she had nothing to do with her husband’s death. What does she say happened that night? And, how does she explain moving on with a new man, weeks after Aaron’s death? Plus, hear the coroner’s autopsy report — was anything suspicious found? Emotions run high when Fawn and Lorrie face each other on Dr. Phil’s stage. How does Fawn answer to Lorrie’s allegation that she once threatened to kill Aaron? And, why did Aaron file a protective order against Fawn one month before his death? Dr. Phil sorts through the details and enlists the help of a toxicologist to provide some answers. Could Aaron have been poisoned to death?
