A website set up to help find the body of a murdered Bangor woman has been visited by people "close" to the alleged suspects, her sister has said.
Information can be given anonymously on the website
The family of Lisa Dorrian, 25, who went missing last February, launched the website before Christmas and says it has received five million hits.
Her sister Joanne said the family had been heartened by messages of support.
She said she did not expect any new leads, but hoped for information which would lead them to Lisa.
Lisa was last seen at a party on a caravan a site in Ballyhalbert, County Down, on 28 February 2005. Despite extensive land and sea searches her body has never been found.
Detectives believe it could have been hidden in water.
"There are probably very few people who know where my sister is at this moment in time," said Joanne.
"But it's the people around them that are giving in names and saying: 'I think such and such is responsible, I've heard this talk, I've heard that talk'.
"Things like that that are going to lead us closer to Lisa.
"It is saying that these people aren't hiding it as well as they would like to think they are, people around them believe they are guilty. It is just asking that the right people who know a bit more, to come forward."
Lisa Dorrian's family hope the website will generate information
Police believe members of the Loyalist Volunteer Force may have been involved in Lisa's killing.
The Lisa Dorrian website contains a page where information about her disappearance can be given anonymously.
It also features information about Lisa, from her childhood to the day she disappeared, as well as a section for messages of support for the family.
Joanne said that people were more likely to post information on the website than go to the police.
"The suspects are there, they always have been there, the only new information that we would want is where Lisa is.. .that is what the whole focus of this website is, to find out where my sister is," she said.
"I know most things going on in Lisa's investigation. I'm able to say if something is just a rumour or may lead to something else.
"I would like to thank all the people who have put confidential messages on the board, because they will be fully investigated."
Joanne said the family had been overwhelmed by the response to the internet site particularly over the Christmas period.
"Christmas was extremely hard," she said.
"It meant that on Christmas Day when we were all feeling low, without Lisa, that we were able to go onto the website and have a look.
"People actually took the time to go onto the website on Christmas Day, when they were with their own families, and leave messages of support for us."
A forensic scientist looking at the cases of the Disappeared is also working on Lisa's case.
The scientist is being funded by the British and Irish governments to help locate the remains of five people abducted, murdered and secretly buried by the IRA during the Troubles.
