Two men in England have been arrested on suspicion of murder in the death last year of a 17-year-old girl from Latvia, a spokesperson for the Norfolk Constabulatory announced May 1.

The men, ages 28 and 31, were arrested in King’s Lynn, which about 160 kilometers north of London. They were being held as suspects in the murder of Alisa Dmitrijeva, whose body was discovered Jan. 1 on the British royal family’s Sandringham Estate at West Norfolk, northeast of London. However, later in the day they were released on bail, police said.

Dmitrijeva disappeared at the end of August and was reported missing on Sept. 6, police said. A person walking their dog on New Year’s Day found the body in a wooded area of the estate.

Police used a DNA profile and a palm print to identify the remains as those of Dmitrijeva, police spokesperson Lisa McGrann said in a news release.

The car in which she was believed to be last seen was found at the end of January in a scrapyard, police announced in March. As part of their investigation, police have examined soil and debris samples found in the car, as well as closed-circuit video footage.

Dmitrijeva and her family moved to Great Britain in 2009.
