POLICE have confirmed that a review of their investigation into the death of a 17-year-old student whose body was found on the Queen’s Norfolk estate is under way.

But a spokesman for the Norfolk force said it was “routine” in unsolved murder cases.

The remains of Alisa Dmitrijeva, 17, from Wisbech, were found by a dog walker at Anmer, near Sandringham, on New Year’s Day, 2012. Alisa, who was due to enroll at the College of West Anglia, had been missing from her home in Railway Road since September.

Two men have been questioned over her death but no-one has been charged.

A coroner’s inquest has been postponed after police said they needed more time.

A Norfolk police spokesman said: “Preparation for a file for the inquest continues, and as is routine in such cases that remain unsolved, a review of the investigation is taking place to ensure nothing was overlooked. This will need to be completed before any inquest takes place.”
