There are people in the community who could help find the body of missing Bangor woman Lisa Dorrian, the senior investigating detective has said.
Lisa left her handbag and personal belongings behind at a party
Detective Superintendent Pat Steele said this would help bring closure to the 25-year-old's family.
Four members of the public have come forward with information following the family's appeal last week, he said.
Lisa disappeared after a party at a caravan site in Ballyhalbert in County Down on 28 February.
Det Supt Steele called on those in the community where Lisa lived and socialised to contact police or Crimestoppers so the family could bury their daughter and grieve properly.
At last week's appeal, Lisa's family made a public appeal for anyone who knows where her body is to contact the police.
They said it had been a very difficult two weeks and thanked people for their support.
It was the first time the family had spoken publicly since detectives announced they were treating the disappearance as murder.
Three men who have been questioned about the killing have been released.
When she disappeared, Lisa, a shop assistant, left her handbag and personal belongings behind her and has not made contact with friends or family since.
A caravan from the site has been removed for examination.
Extensive air and land searches have taken place since her disappearance. Underwater search teams were also used.
