The family of murdered Bangor woman Lisa Dorrian is offering a £10,000 reward for information leading to the recovery of her body.
Lisa Dorrian's body has never been found
The 25-year-old disappeared after a party at a caravan site in Ballyhalbert in County Down on 28 February.
Her body has never been found despite extensive air, land, and sea searches. Three men were questioned about the killing but later released.
Lisa's father John Dorrian said her death had "ripped the family apart".
He told a news conference that they could not move on until they "gave her a Christian burial".
A senior detective has said there were people in the community who could help find her body.
Graffiti in the area following her disappearance suggested a link between the case and the Loyalist Volunteer Force.
When she disappeared, Lisa, a shop assistant, left her handbag and personal belongings behind her at the caravan park.
A caravan from the site was removed for examination.
Last month, the police revealed that four members of the public had come forward with information following an earlier appeal by her family.
