A mob lynched a 24-year-old Black man named John Buckner in 1894. That's not disputed. But it's the location of Buckner's lynching that's creating controversy in Valley Park. Geoff Ward, a professor of African and African American Studies at Washington University and a member of the Reparative Justice Coalition, discusses the killing of John Buckner and how the record shows he was killed in Valley Park. Elizabeth Simons, community program manager for Great Rivers Greenway, describes the group’s plan to install a plaque on the Meramec Greenway.
