This week, Natalie talks about forensic pathology: the medical science that determines how and when a person died. She explains how our bodies decay, and what clues a crime victim can provide to catch their killer. From cadaver dogs to blow flies, hyoid bones to undigested fries - the dead never lie. Then, Erin presents a case where investigators used every forensic tool in the book to get justice for a girl who vanished into thin air. And Kathleen unravels the layers of a famous vintage crime so brazen & bizarre, it ended in a trans Atlantic boat chase - or did it? *You'll need a strong stomach for this one, folks.*
