Serial killer Rex Heuermann will be sentenced in June for killing and dismembering eight women on Long Island, New York. Now, we’re venturing into the dark psyche of a human being capable of such brutality, to ask the question… Why? In this episode of Criminally Obsessed, we sit down with forensic psychologist Dr. John Delatorre to break down the mindset of a serial killer, from what drives their choices to why their actions can feel compulsive and calculated at the same time.

Heuermann admitted his crimes to his own daughter, Victoria Heuermann, and ex-wife, Asa Ellerup, as captured in the Peacock documentary The Gilgo Beach Killer: House of Secrets, where they describe coming face to face with the truth. After watching the doc, we have questions… Like how did a husband and father murder multiple women not only in his home, but the crime scene was his childhood bedroom?

We explore the psychology and facts of a case that is truly stranger - and darker - than fiction.
