Jack Armstrong went missing after collecting a customer in Cardiff in 1979

''Modern scientific DNA techniques could help police finally identify the killer of a Cardiff taxi driver more than 40 years ago.
The body of Jack Armstrong was found in October 1979 after he picked up a fare in Cardiff.
It was the beginning of what was at the time, one of South Wales Police’s biggest investigations.
On the afternoon of Friday, 5 October 1979, Mr Armstrong answered a call to pick up a fare from the Fairwater area of the city. Shortly after 1pm, was the last time anyone heard from him.
Despite an intense investigation, police's efforts were unsuccessful in catching the killer, and the case has remained a mystery for the last 40 years.
But, a new team of detectives and forensic experts are re-examining the evidence with the help of new DNA techniques. Their painstaking work will be shown in an exclusive behind-the-scenes documentary on S4C called Llofruddiaeth Jack Armstrong (The Murder of Jack Armstrong).''
"We know that this man was very dangerous in 1979 – what else has this man done in the last 40 years?”
''Evidence from the case, including Jack’s clothes have been carefully stored by the police for more than 40 years and it is possible that the murderer left traces of their DNA when they attacked Jack – and that is the hope of the specialists working on the case.''

- ''What do police know?
- On Friday 5 October, a phone call was made to Castle Cabs asking for a taxi. The man gave his name as Mr Williams and asked for a taxi from Fairwater to Cowbridge.
Later that evening, police were called to the Treoes area, a small village outside Bridgend, nearly 20 miles from Cardiff. A resident called to say that a car had been left on a secluded road. The car was Jack Armstrong’s taxi.
Blood was found in the taxi and there was no sign of Jack.''
Shortly before the car was reported to the police, eye witnesses saw a man cleaning the inside of the car. This man was described as around 20 years old.''
