The parents of a woman who went missing 10 years ago have used the anniversary to make another appeal for information.
Police hope clubbers from 10 years ago may have information
Melanie Hall, then aged 25, went out to Cadillacs nightclub in Bath on June 9 1996 and has not been seen since.
Despite extensive searches, the offer of a £10,000 reward and several television appeals, no trace of the hospital clerk has ever been found.
"We feel somehow that we're running out of time - we would just like an outcome," said Miss Hall's mother Pat.
"You have to try to lock the awfulness of the truth at the back of your mind," said her father Steve.
There have been several leads, the last in 2003, centred on a field near Inglesbatch on the edge of the city, but nothing came of it.
An inquest in 2005 recorded an open verdict - but brought no comfort to her parents.
Melanie's parents are desperate to know what happened to her
"I thought it might actually bring an end to the feeling that we needed to do something to mark her death but in fact it didn't," said Mrs Hall.
The police are still hoping someone will come forward with information about Miss Hall and how she left the nightclub.
"There are people who know what happened when they were at Cadillacs," said Detective Inspector Ian Glover of Avon and Somerset Police.
"They may have been late teenagers then but after 10 years people mature and can think about things they maybe couldn't deal with at the time and all we ask is that they pass it on to us," he added.
