London, July 23 (IANS) A convicted child killer has been sentenced to 27 years in jail for the murder of a 17-year-old girl in Britain 46 years ago.

Yolande Waddington, who worked as a nanny, was found strangled in Beenham village in Berkshire in October 1966, BBC reported Monday.

David Burgess, now 64, is already serving a life sentence for killing nine-year-old girls Jeanette Wigmore and Jacqueline Williams in Beenham in 1967.

The jury at Reading Crown Court convicted Burgess by a majority verdict of 11 to one following a five-week trial.

Waddington had moved to the village only a few days earlier to work as a nanny at a farm when she was killed.

In 2011, Thames Valley police carried out a review into the case. Using a new technique, they obtained a partial DNA profile which matched that of Burgess.
