On the morning of Wednesday, August 1st, two fishermen saw a bundled object floating in the Chattahoochee River near the Interstate 285 bridge. A short time later, they saw that the object had become hung up on a rock, waded out to get a closer look, discovered that it was a man’s body, and called 911. Cobb County Police & Fire recovered the body. Investigators determined that the man – identified as Ralph McGhee, 39, of Decatur – had been shot to death outside of the park. On August 4th, Cobb County fugitive investigators and U.S. marshals arrested McGhee's housemate, 39-year-old Hajja Kennyatta Martin, and charged Martin with felony murder and aggravated assault.
