The family of the Co Down woman believed murdered by loyalists began an advertising campaign today in an effort to recover her body.
Lisa Dorrian has not been seen since she left a party at a caravan site at Ballyhalbert on the Ards Peninsula coast on February 28th.

In a bid to jog people's memories a large trailer-mounted advertisement bearing a picture of the missing Bangor woman has been produced and was being towed around the peninsula tonight.
Lisa's sister Joanne said it was the first stage of an advertising campaign. She said it was being mounted "in the hope that it will be seen by the right people, the people involved, and they will finally feel the need to do the right thing and they will finally put us out of this misery that we are enduring day by day”.
The Dorrian family will tonight attend a fundraising night in aid of The Lisa Dorrian Appeal Fund.
It consists of a motorbike run around the a Ards Peninsula with the advertising hoarding - stopping at the caravan site where she was last seen - followed by a barbecue and music in Newtownards.
The missing woman's father, John said: “People have been more than generous so far and we hope that it will continue. We just need the right bit of information to lead us to Lisa and we beg those involved and those who may suspect where she could be to tell us or the police.”
The family have already offered a £10,000 reward for information leading to the recovery of her body and last week they unveiled a blue ribbon campaign to keep the case in the public eye.
Police are looking at the possible involvement of members of the Loyalist Volunteer Force in the killing. Four people have so far been arrested for questioning by detectives, but all have been freed without charge.
