The mystery of who killed a Norfolk schoolgirl close to her home remains unsolved after a nationwide appeal to coincide with the 25th anniversary of her death drew a blank.
Teenager Johanna Young was found lying face down in a flooded pit on the edge of Wayland Wood, Watton, on Boxing Day in 1992.
The 14-year-old had been missing for three days after leaving her home in Merton Road to meet some friends.
A spokesman for Norfolk Constabulary said: 'No significant information has been received following the 25th anniversary appeal.
'However, we would continue to urge anyone with information that could offer Johanna's parents closure to come forward.'
One week after the anniversary appeal, there was some new hope as police chased two new leads but they came to nothing.
Det Ch Insp Marie James, of the Norfolk and Suffolk Major Investigations Team, said: 'Johanna Young is a daughter, a sister and a friend who continues to be dearly missed by those still struggling to come to terms with her death.
'They are left wondering what happened to her, what the events are which led to her death and who is responsible and always wondering if it is someone they knew.
'Twenty-five years ago it was never established who was responsible for her death and the case remains open and we will follow up any new lines of inquiry.'
Johanna's parents, who still live in Watton, have supported frequent media appeals in a bid to get some closure in the murder of their daughter.
A post-mortem examination revealed she had died from drowning after suffering a fractured skull.
She was found with her lower clothing removed and her jeans missing, although there was no evidence of a sexual motive.
A witness described spotting a couple leaning on a motorbike at the end of Griston Road, near where she was found, though they have never been identified.
Three people had been arrested in relation to the murder over the years but no charges have ever been brought.
Anyone who has any information, even if it may seem small or insignificant, is urged to contact the Major Investigations Team on 101 or Crimestoppers anonymously on 0800 555111.
