Johnnie Mae Chappell (c. 1929 – March 23, 1964) was an American murder victim during race riots in Jacksonville, Florida, killed by a gunshot from a passing car. After evidence and documents went missing her killer was charged with manslaughter - only serving three years in prison - and the other passengers were never charged. Detectives working the investigation claimed they lost their jobs due to their complaints regarding police racism and how the case was handled.
