In 2012, mother of two, Michelle Warner, vanished without a trace after arguing with her live-in ex-boyfriend, Mark Castellano. Authorities say that Castellano exhibited bizarre behavior just after Michelle's disappearance, claiming that Warner had abandoned her children. He then did an interview with Dr. Phil in which he denied knowing what had happened to his ex. "I felt in my bones that Mark knew more than he had initially let on," says Dr. Phil in part two of the crime podcast, "Twisted Love: Bringing a Murderer to Justice," Mystery and Murder: Analysis by Dr. Phil . "I noted he was going out of his way to make her seem like a bad person." New episodes drop every Thursday. See omnystudio.com/policies/listener for privacy information.
