British police are distributing posters in four languages, including Latvian, as they seek information into the murder of 17-year-old Alisa Dmitrijeva, whose body was found New Year’s Day on the royal family’s Sandringham Estate northeast of London.

Police confirmed Jan. 8 that the body, which may have been in place for up to four months, is that of Dmitrijeva. The young woman, who was born in Latvia and moved with her family to Great Britain in 2009, was last seen alive in late August.

Detective Chief Inspector Jes Fry, head of the Joint Norfolk and Suffolk Major Investigation Team, said he hopes people from within Eastern European communities in King’s Lynn and Wisbech may be able to assist.

“Alisa socialised within her own ethnic community and so those people may remember seeing her in the timeframe we’re looking at, between midday on Tuesday, 30 August, 2011, and midnight on Tuesday, 6 September, 2011, or may have heard something about her disappearance and death,” Fry said in a press release from the Norfolk Constabulatory.

The posters were issued Jan. 10.

“We have access to a language line and interpreters who can help anyone calling Norfolk Constabulary,” Fry added.

Anyone with information about Dmitrijeva’s disappearance and death may contact the Joint Norfolk and Suffolk Major Investigation Team at Norfolk Constabulary on +44 01953 424242, or Crimestoppers UK at +41 800 555 111.
