Hundreds of unsolved crimes – including the murder of Barbara Mayo – could be cracked thanks to updates to the police fingerprint database.
Barbara Mayo, a 24-year-old hitch-hiking student teacher, was brutally raped and strangled and her body dumped in Ault Hucknall Woods, near Glapwell, in 1970.
Despite it being the biggest murder investigation seen in the country at the time, the killer has never been found.
But thanks to the painstaking work of Derbyshire Police fingerprint experts, the case – alongside 600 others – could be closer to being solved.
Prints from crime scenes across the county which were committed before the creation of a national police fingerprint database, have been inputted on the system, which will flag up matches from new arrests.
A spokeperson for Derbyshire Police, said: “In recent years, we have been able to re-open historic cold cases because of fingerprint matches made by our identification experts.
“Whenever fingerprints are taken from suspects, they are run through the national database.
“Should a match be made against fingerprints taken at an old crime scene, that crime will be re-opened.”
