The family of a murdered shop assistant has launched a website in a fresh bid to find her body. Lisa Dorrian (25) went missing from a caravan site in Ballyhalbert, on the Co Down coast, in February.
But despite extensive searches and high-profile appeals by her family, no trace of the young Bangor woman has been found.
Her sister, Joanne, said the website - www.lisadorrian.co.uk - would bring global attention to the case.
"It contains a storyboard of Lisa's life from her birth to the day she disappeared, a page for messages of support from the general public and a page for her friends. There is also a confidential information page which is completely anonymous and cannot be traced.
"At this time of year someone can put us out of our misery and tell us where she is. Any small piece of information could provide the final piece in the jigsaw that we need."
On the build-up to Christmas, Joanne said: "It is extremely difficult and one of the hardest times of year we have had.
"It is 10 months on now and in the next few months it will be difficult to be positive as the first anniversary is coming up.
"I have found myself going out to buy presents and just going through the motions for the children in the house.
"They have been talking about Lisa and how she is not going to be here."
A number of messages have already been posted on the site, including a tribute from Lisa's ex-boyfriend, Jamie Mills.
"We did everything together, walking, holidays, partying, laughing, we were inseparable. Now she is gone it is a living nightmare for everyone who loved her and cared about her... I pray every night that these people will find it within themselves to say where she is, to stop the endless days of hurt and pain that everyone is going through."
One line of inquiry was that loyalist paramilitaries were involved in the murder. But it is understood the senior investigating officer now does not believe that to be the case.
