At the terminal three car park at London’s Heathrow Airport a K-reg Ford Cortina had overstayed its time by several days, prompting irritated officials to call the police. They opened the boot and inside found the body of the owner, 39-year-old West Indian mini-cab driver Stephen Sylvester. He had died of multiple stab wounds, one of which had penetrated his heart.

Sylvester disappeared after taking a 2 a.m. call on Thursday evening, November 17th, 1983, from his home in Hounslow. He lived only a few minutes from the airport, but his car wasn’t parked until 4 a.m. His body was found the following Monday.
