The night Glenis Carruthers was murdered

On 19th January 1974 Glenis Carruthers travelled from Bedford, where she was a student, to attend a friend's 21st Birthday party on Worcester Crescent in Clifton, Bristol.

At around 10.20pm Glenis left the party, possibly to get some fresh air or to make a call from a telephone Kiosk, situated nearby.

Just after 11.00pm there was a sighting of Glenis on the Clifton Downs. The witness thought he saw a courting couple on the grass. A short time after her body was discovered. She had been strangled to death.

The witness described the man as white, between 20 to 25 years old; around 5ft 10inches tall in height, medium build, with brown shoulder length hair. He was wearing a three-quarter length coat and a denim type cap.

At the time of the murder 175 officers assisted the investigation and more than 16,000 people were interviewed, however no information was obtained to identify the offender.

Over the last 36 years this case has been reviewed twice and further items are being submitted to the Forensic Science Service for further examination. It is hoped this may provide a vital breakthrough.
