On October 5, 1979, taxi driver John 'Jack' Armstrong collected a a customer from Cardiff. Apart from a radio call saying he had picked up the customer the 58-year-old was never heard from again. Three days later he was found murdered in Cowbridge. Nobody has been convicted of the murder.
However police officers hope that modern scientific DNA techniques could help identify Jack's killer. Painstaking work to find a DNA profile in the case was shown in a behind-the-scenes documentary on S4C. which explored the work the South Wales Police major crime review unit has undertaken in forensically reviewing the case.
Jack answered a call to pick up a fare from the Fairwater area of Cardiff on the afternoon of Friday, October 5, 1979. At around 1.30pm he radioed in to confirm that he had picked up the customer from outside a Fairwater pub. However he was never heard from again.
