Walker was 75 years old, a retired Collierville Police officer, and was working at his family’s convenience store at 191 West Street in that town when he was fatally shot in a hold-up. Although shot in the stomach, Walker was able to place a call to 9-1-1. He died at the hospital. No one has ever been charged with Walker’s homicide.
Nineteen years later, the City of Collierville, decided to dedicate a bridge in Walker’s honor. Walker had been Collierville’s first African American policeman.
