Who killed 6-year-old Jeremy Guillory in 1992 is not a mystery. Pedophile Ricky Langley is serving a life sentence in a Louisiana prison for strangling the child and hiding him in his closet. But the case still haunts many associated with it. Alexandria Marzano-Lesnevich, whose book "The Fact of a Body: A Murder and a Memoir" explores the case, visits with Nancy Grace in this episode. Grace is also joined by forensics expert Joseph Scott Morgan, author of "Blood Beneath My Feet: The Journey of a Southern Death Investigator" and New York psychologist Dr. Chloe Carmichael, creator of AnxietyTools.com.
