A notorious "slave pen" in the heart of St. Louis trafficked thousands of men, women and children in the years before the Civil War. In January, a new plaque will be unveiled near its original location, now a parking garage across from Ballpark Village and Busch Stadium. Kenneth Winn, a former Missouri archivist and author of the plaque’s inscription, shares the history of the slave pen and its owner Bernard Lynch. Also, reporter Rocky Kistner discusses the years-long effort to place the memorial and his own family's experience in acknowledging an ancestor's ownership of enslaved people in St. Louis.
