Love, Lies and Murder: Killer Doctor's Daughter Reacts to Mistress Interview Dr. Phil : Season 12 Episode 59

Alexis, the 30-year-old daughter of Dr. Martin MacNeill — who was recently convicted in the 2007 murder of his wife, Michele -- speaks out about why she helped prosecutors build a case against him and reacts to the recent Dr. Phil interview with her father’s former mistress, Gypsy Willis. Did her mother suspect that her father was having an affair? Alexis opens up about her parents' relationship in the months before her mother’s death. Prosecutors accused the Utah doctor of coercing his wife into having plastic surgery so that he could heavily medicate her during recovery and drown her in the bathtub. Hear about concerns Alexis says her mother had before undergoing surgery — did she fear for her safety? And, what does Alexis claim her father did in the days after the surgery that, in hindsight, she feels was a major red flag? Then, Alexis describes the first time she met Gypsy, whom her father introduced as the family’s new nanny — did she suspect there was something more going on between them? And, hear why Alexis says she believes that Gypsy knows more about her mother's death than she's admitting. Plus, how does Alexis feel about her father? Will she ever speak to him again?
