David Burgess killed nanny Yolande Waddington, 17, in Beenham, Berkshire, in 1966.

Burgess was previously convicted of murdering two nine-year-old girls in the same village in 1967.

Yolande was last seen alive at the Six Bells pub on the evening of Friday, October 28, 1966. At 10pm, she walked from the home where she was working as a nanny into the village to post a letter to her boyfriend. While there, she went into the pub to buy some cigarettes. It was the last time anyone saw her alive and her naked body was found in a ditch two days later, prosecutor John Price, QC, said during the trial at Reading Crown Court .
