Sandringham murder: Alisa Dmitrijeva investigation 'exhausted'
Detectives investigating the murder of a teenager found on the Queen's Sandringham Estate said they have no new leads and were passing the case to the coroner.
Latvian Alisa Dmitrijeva, 17, went missing from her home in August 2011.
Her body was found on New Year's Day 2012. Two men questioned over her death were released without charge.
Norfolk Police said the case would remain open, although are not actively pursuing new information.
The last-known sighting of Alisa, who lived in Wisbech, was in Friar's Street, King's Lynn, at 12:15 BST on 31 August 2011.
She was seen in a green Lexus car with two men.
Her partially-clothed body was found in a copse at Anmer on the afternoon of 1 January 2012.
Images of missing clothing similar to that worn by Alisa were released as part of the police appeal for information last year.
At the time, Det Insp Marie James said the force was pursuing "several possible new lines of inquiry".
But the decision has now been made to pass the case to a coroner, "despite exhaustive inquiries", she said.
"Any new information or leads will be followed up and acted upon," said Det Insp James.
The inquest will take place at King's Lynn County Court at a later date.
