Police have started searching a beach car park at Snettisham for clues into the murder of Alisa Dmitrijeva.

Detectives now believe Alisa, 17, may have visited the car park in the early hours of August 31.

She was reported missing by a family member on September 6 and her remains were found on the Royal Estate at Sandringham, on New Year's Day.

Specially-trained detectives have been searching around the car park for Alisa's mobile phone and other objects which may have belonged to her.

The car park borders a remote stretch of beach which leads south towards the Royal Estate, as well as a caravan park and an area of scrub land which stretches north towards Heacham.

Ever since the badly-decomposed body was identified by a DNA sample, police have been trying to piece together the Latvian-born student's last movements. She was seen shortly after midnight in Friar's Street, in King's Lynn.

Today Det Chief Insp Jes Fry, who is leading the hunt for Alisa's killer, said: 'I would still ask the local communities in Wisbech and King's Lynn to think back to the August Bank Holiday and following week in September last year, and to get in touch if they have any information about Alisa's whereabouts during this time.

'We particularly want to hear from members of the Latvian, Lithuanian and Russian communities who may have known Alisa. We have had multi-lingual posters put up in key locations to encourage people to come forward and we are in the process of trying to have an appeal played on radio stations listened to by these communities.

'As well as sightings of Alisa herself, I am particularly keen to try to find her black LG GM360 mobile phone, or to hear of any sightings in the Kings Lynn and Wisbech area of the bottle green P-registration Lexus GS300 that Alisa was last seen in on 31 August 2011.'

Anyone with any information should call the Norfolk and Suffolk Major Investigation Team on 101.
