Betty Jo Richards was 17 when her body was found in an alley in Quinton, Alabama on July 16, 1972. She was white and had been stabbed more than ten times. Witnesses said a white man chased a screaming Richards into the alley shortly before her body was discovered.

A 30-year-old man named Thomas G. Barnett was detained early in the investigation but was released without charges. The case went cold for years until convicted serial killer Jack Harrison Trawick later confessed to encountering Richards in downtown Birmingham, forcing her into an alley and stabbing her to death. Trawick was already on death row for other murders and was not prosecuted for Richards’ killing; he was executed by lethal injection on June 11, 2009.

What can someone who remembers Quinton or that July day add to help finally close this case?
