 An urgent manhunt in Chicago for the suspect who killed a postal worker. 48-year-old Octavia Redmond delivering mail on Chicago's south side when police say a man approached late Friday morning and shot Redmond several times, the gunman fleeing in a vehicle. Elise Foster, who's president of the National Association of Letter Carriers, a local branch, says the family's devastated. I know her husband. He's a letter carrier, also an assistant union steward at the station. She's just a great person. Redmond, a grandmother loved by people on her route.
