For our 48 Hours listeners, we give you the first episode of our new podcast, “My Life of Crime with Erin Moriarty.” Erin Moriarty takes you behind the scenes and reveals the story behind the story in some of the most suspenseful and heart-breaking cases she’s covered over her career as a crime journalist. Subscribe to this new podcast today! Erin Moriarty takes us to Fall River, Massachusetts, where one of the most sensational crimes of the 19th century took place. The crime inspired the dark nursery rhyme “Lizzie Borden took an axe and gave her mother 40 whacks. When she saw what she had done, she gave her father 41.” Despite what everyone thinks they know, there is a stunning verdict in the case. In part 1 of this unusual road trip, Erin takes us to the scene of the crime - the house where the murders took place is now The Lizzie Borden Bed and Breakfast/Museum. We learn about the Borden family and what happened on that fateful day in August of 1892. It was a brutal crime scene and there are actual death photos hanging in the house. Erin will spend the night here. She is looking for a motive, evidence and maybe a ghost or two.
