DNA hunt could identify killer who struck in 1946

Detectives are using DNA material stored for six decades to try to trace the relatives of a man who raped and murdered a schoolgirl in 1946.

The investigation into the death of Muriel Drinkwater, 12, a Swansea grammar school pupil, is believed to be the world’s oldest cold case review.

Colin Dark, of the Forensic Science Service (FSS), said that if Muriel’s killer was still alive he was likely to be in his eighties.
