The detective leading the investigation into Alisa Dmitrijeva’s death is pleased with the public’s response to a fresh appeal.
But Det Insp Marie James says it is too early to say if any of the new lines of inquiry will take the investigation further forward.
Last week marked the second anniversary of 17-year-old Alisa’s disappearance. Her partially clothed body was found on January 1, 2012, hidden in an isolated woodland on the Sandringham estate.
Det Insp James said: “It is pleasing that people have taken the time to call in and every call will be responded to. We would look to have face-to-face interviews with the individuals who have called in to glean further information.
“I remain hopeful it will take the investigation forward but at the moment it is too early to say.
“I do still need help in solving this mystery.”
None of the calls have so far related to Alisa’s missing jeans, pink top and coat.
Det Insp James said: “I remain hopeful but I have to realistic as it has been two years.
“I have no doubt that someone out there has knowledge of these items.”
The last confirmed sighting of Alisa, who lived in Wisbech, was in Friar’s Street, Lynn, at 12.15am on August 31. But she is thought to have gone onto a party at Snettisham beach.
Det Insp James said: “We strongly believe that Alisa went there in the early hours of August 31. I would appeal to people to cast their minds back.”
Last week Alisa’s family supported the investigation by releasing a picture of her grave in Latvia and are pleased with the response.
Det Insp James said: “She was an innocent young girl.”
Anyone with information should call 101.
