Police are reported to be investigating the disappearance of a 17-year-old teenage girl as they seek to identify a body found on the Queen's Sandringham estate on New Years Day.
Detectives are examining links to cold cases nationwide after the body of a young woman was found by a dog walker near the village of Anmer, about a mile from the main gate to Sandringham House.
According to reports, one of the missing persons cases to be looked at is that of Latvian-born teenager Alisa Dmitrijeva, who disappeared after midnight in King's Lynn on 31 August.
Dmitrijeva, from Wisbech, Cambridgeshire, was reported missing by a relative on 6 September and a £5,000 reward was offered for information that helps officers find her.
The body had been at the site for between one and four months.
"The pathologist believes it is highly unlikely the death was through natural causes. There is no evidence of accidental injury, damage due to firearms or bladed weapon," a Norfolk Police spokesman was quoted by the Press Association as saying
"Samples have been taken which should provide a DNA profile within the next 24 hours."
Speaking to journalists at the scene, Detective Inspector Jes Fry said: "How far back this investigation goes depends on what the experts say. We are looking at missing persons reports nationwide as well as cases we have been working on more locally for potential links."
Detectives did not say yesterday whether the body was fully clothed.
Fry said: "I cannot confirm whether she was clothed because, at the moment, only my staff, the person who found the body and the person or people who put it there know that and I would like it to stay that way.
"The body was found by a dog walker and was not underground. At this stage we do not know who the victim is."
Fry said it was not yet clear if the woman was killed at the scene or taken there after death.
Pathologist Nat Cary arrived at the site yesterday to examine the body and entomologists were looking at insect life on the body to establish how long it had been there.
Fry said police had informed the Sandringham estate about the find and officers responsible for protecting the royals had been updated on the situation.
The Queen and the Duke of Edinburgh are currently in residence at Sandringham, along with the Earl and Countess of Wessex.
One Anmer resident said: "We were all aware of the police activity and normally in this area gossip travels fast. But at the moment we know very little other than the fact a body has been found."
