A CONVICTED murderer has been sentenced to life imprisonment for the murder of teenage girl Claire Woolterton 32 years ago.

Colin Frederick, 66, will serve at least 24 years for killing the 17-year-old (pictured), who lived in the Yeading area and whose body was found on a Thames towpath in Windsor on August 28 1981.

Her throat had been slashed in the sexually-motivated attack.

The case went cold, and no-one had been brought to justice until now. The case was reopened in 2011, and by using DNA analysis methods unavailable to police at the time, officers made the crucial breakthrough and found samples matching Campbell's on adhesive tapings lifted from the body.

Jurors heard that it was more than one billion times more likely to have come from Campbell than another unknown party.

Colin Campbell, jailed for life for the murder of Claire Woolterton in 1981
Campbell was charged over the murder in December 2012.

He denied involvement, but was found guilty after a trial at Reading Crown Court, by a majority verdict of 11 to one. He was jailed for life yesterday (Wednesday).

Campbell, originally from the Hanwell area, is already serving a life sentence for the murder of 29-year-old Deirdre Sainsbury, whose mutilated body was dumped in a woodland off Denham Golf Course in Buckinghamshire, on December 22 1984.
