On May 1, 2007, 47-year-old Shelby Polk Jr. was found dead beside a fence at the Biker’s Corner on North Market Street in St. Louis. An investigation determined he suffered a fatal gunshot wound to the chest that appeared to have been fired at close range. No suspects were immediately identified and no arrests have been announced; the killing remains unsolved.

The Polk family endured further tragedies in later years: Shelby Polk III was shot in 2015, crashed his car and died of his injuries; Shelbyon Polk, 19, was found shot to death in a vacant yard on Thanksgiving morning in 2017; and in December 2018 Karen Arnold, Shelbyon’s grandmother, was found murdered in her Kirkwood home. Family members believe the cases may be connected, but none of the homicides has been solved.

Did anyone in St. Louis remember Shelby Polk Jr., his family, or see anything around North Market Street on or around May 1, 2007?
