The mother of Lisa Dorrian would talk to loyalist paramilitaries if it meant getting her murdered daughter's body back, she has told the BBC.
Patricia and John Dorrian appeal for help to find Lisa's body
Mainstream paramilitary groups have been carrying out their own "inquiry" into Lisa's disappearance after a party in Ballyhalbert on 28 February.
Her body has never been found. Three men were questioned about the killing but were later released.
The police are looking at the possible involvement of members of the LVF.
"We'll talk to anybody, but we don't want any retaliation or comebacks," Pat Dorrian told the BBC's Spotlight programme.
When asked whether she wanted "paramilitary justice", Mrs Dorrian said she did not.
She added: "If they can help, I would be really grateful".
The family is offering a £10,000 reward for information leading to the recovery of Lisa's 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.
