The killing of an RAF worker in a Buckinghamshire village 40 years ago is to be reopened by Thames Valley Police.
Rita Irene Ellis, who was 19 when she died, was killed in the village of Halton on Saturday 11 November 1967.
Miss Ellis, an employee at RAF Halton near Aylesbury, was found the next day near Rowborough Copse in Halton. A man was questioned at the time.
Thames Valley Police major crime review team has reopened the case and said it will use DNA and forensic techniques.
Detectives now hope someone who lived in the area, at the time close to a coal storage yard, might have some information which could help them with the case.
Evidence from the original case has been kept in the force's large archive and storage facility and will be examined using the modern techniques now available.
The review team was formed in March and will be examining all unsolved murders and rapes which have happened in the past 50 years in the Thames Valley area.
