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.
