Detectives investigating the murder of a teenager found on the Queen's Sandringham Estate in Norfolk do not yet know how she died, an inquest has heard.

Alisa Dmitrijeva, 17, was discovered by a dog walker in Anmer, near King's Lynn, on 1 January.

Detectives think she was murdered within days of her disappearance in August.

A multi-lingual poster has been created to appeal for information.

The inquest in Norwich heard tests were continuing.

Norfolk coroner William Armstrong, opening the brief hearing, said a post-mortem examination had failed to find a cause of death.

Ethnic community

Alisa was born in Latvia and moved to the UK with her family in 2009.

Norfolk police have created a poster in Latvian, Lithuanian and Russian to appeal to people in those communities in King's Lynn and Wisbech to come forward with information.

Det Ch Insp Jes Fry of Norfolk Police said: "Alisa socialised within her own ethnic community and so those people may remember seeing her... or may have heard something about her disappearance and death."

Police would like to hear from anyone who may have seen Alisa between midday on 30 August and midnight on 6 September.

Earlier, police said two men previously questioned about Alisa's disappearance were likely to be re-interviewed.

Confirmed sighting

The men are known to have collected her in a P-registered green Lexus car around midnight on 31 August - the last confirmed sighting of the teenager.

They are described as acquaintances of Alisa and told officers they dropped her off at an Asda supermarket in Wisbech, the Cambridgeshire town where she was living.

Officers have also received information that she may have been seen in King's Lynn on 31 August, about 45 minutes after the last confirmed sighting.

People who organised events at Sandringham between 30 August and 6 September are being urged to come forward.

The Queen and Duke of Edinburgh, who are staying on the estate, have been kept up to date with developments in the case.
