Body found on Sandringham Estate 'identified on Monday'

The woman's remains were found on the Queen's Sandringham estate by a dog walker

A woman whose remains were found on the Queen's Sandringham Estate in Norfolk is expected to be identified on Monday, police have said.

The body of the woman, thought to have been aged between 15 and 23, was found by a dog walker in Anmer, near King's Lynn, on New Year's Day.

A series of forensic tests to identify the victim have been carried out over the weekend.

Norfolk police are treating the case as murder.

Experts have so far struggled to obtain a useable DNA profile for the woman from tooth and muscle samples.

It is hoped a more detailed analysis on bone ground into a powder will give a definite identification by Monday.

'Substantial progress'

The woman is said to be white, between 5ft 4in (1.6m) and 5ft 6in tall with high cheek bones.

Police teams have carried out a detailed search of a wooded area on farmland at the 20,000-acre (8,000-hectare) royal estate.

An entomologist - a specialist in insects - from the Natural History Museum, visited the estate on Friday to help discover how long the body had been at the site.

So far detectives can only say the body has been there from no earlier than August last year.

Det Ch Insp Jes Fry said: "We have made a substantial amount of progress in this investigation.

"The identity of the victim, once we have that information, will also make a significant difference to the inquiry."

Officers have started examining cold cases across the UK for potential links.

There was no evidence of accidental injury, damage due to firearms or a bladed weapon, police have said.
