Jackson and B.P. look into the history of The Neck, a section of South Philadelphia with a history of pig farming and agrarian life that lasted into the 1950s. As the city grew around it, this section fought for over a century to preserve its way of life. It was also the site of one of the most gruesome mass murders in Philadelphia's history. This episode covers the 1866 massacre of the Dearing Family by Anton Probst.
Part of that coverage involves a can't-miss rant from Jackson that finds a degree of sympathy for Probst and earns every bit of this episode's explicit rating.
