POSTERS have been produced in three foreign languages as police continue their murder inquiry into the death of Wisbech teenager Alisa Dmitrijeva.

Following extensive local, national and international coverage of the case in English, Norfolk Police have had posters produced in Latvian, Lithuanian and Russian to appeal to those communities to come forward with information.

Det Chief Insp Jes Fry said: "Alisa socialised within her own ethnic community and so those people may remember seeing her in the timeframe we're looking at, between noon on Tuesday 30 August 2011 and midnight on Tuesday 6 September 2011, or may have heard something about her disappearance and death.

"A poster has been produced which will be displayed around Wisbech and King's Lynn in key locations. I would encourage anyone with any information, however small or insignificant it may seem, to call us on 101.

"We have access to a language line and interpreters who can help anyone calling Norfolk Constabulary. You can also contact Crimestoppers anonymously on 0800 555 111."

Latvian-born Alisa, 17, who lived in Railway Road, was last seen in King's Lynn's quiet Friar's Street on August 31. She was reported missing by her family on September 6.

A dog walker found human remains on land at Amner, near the Royal Estate in Sandringham, on New Year's Day.

Police cordoned off the scene and a forensic examination was carried out.

After unsuccessful tests to obtain a full DNA profile, identification was made by comparing detail from Alisa's palm with records held which have been further verified by DNA from her femur.

Norfolk coroner William Armstrong has opened an inquest into the death of the student, who was set to begin a business course at the College of West Anglia in King's Lynn on September 1.

The inquest, which was held in Norwich, heard the location the body was found was French's Covert Belt, King's Avenue, Sandringham Estate, King's Lynn.

Mr Armstrong said a post mortem examination was carried out by Dr Nat Carey at the Queen Elizabeth Hospital in King's Lynn, but the cause of death is currently unascertained. He adjourned the inquest to a date to be fixed.

Mr Armstrong said he was satisfied by evidence provided to him that the remains were that of the teenager who had studied an ESOL (English for Speakers of other Languages) course between September 2010 and June 2011 at the college's Isle campus in Wisbech.

College principal David Pomfret said: "We are deeply shocked and saddened to hear the news about Alisa.

"For someone so young with her whole life ahead of her to die in such tragic circumstances is a terrible thing.

"Our thoughts and prayers are with her family at this sad time."
