57-year mystery of missing Birmingham nurse - All we know about the longest-running missing person case for West Midlands Police
West Midlands Police are continuing to investigate their longest-running missing person case 57 years on from the disappearance of a 17-year-old girl.
On the day of her 75th birthday, police say they are still keen to hear from anyone with information on the disappearance of Maria Aldridge, who was last seen in 1968 in Birmingham.
Maria, who was 17 when she was last seen, was training as a nurse at Dudley Road Hospital.
She was last seen between February and June that year and has not been heard from since.
Officers from West Midlands Police's Cold Case Missing Persons team are appealing for any information which could help them find out what happened to Maria.
The team is keeping an open mind as to Maria's whereabouts, as she may simply have left the area and started a new life somewhere else.
Officers investigating are keen to hear from anyone who might know the identity of a man who visited Maria's family home in Stourbridge in May 1968 by the name of Paul or Michael Gough.
This person visited the family address with flowers for Maria's family, but has remained unidentified ever since.
Although Maria had known links in Stourport and Birmingham, police are not ruling out the possibility of Maria moving elsewhere in the country, or leaving the UK all together.
If you know anything which could help in the investigation, call 101 quoting PID number 102618.
