Detectives are still trying to discover the identity of a woman three years after her body was found in the Yorkshire Dales.
The woman's body was discovered by walkers between Pen-y-Ghent and Horton in Ribblesdale on 20 September 2004.
Despite a global police investigation and extensive forensic tests, her identity remains a mystery.
Detectives believe the woman may have had a child and have re-issued their appeal for information.
Det Insp Pete Martin, leading the investigation, said: "Someone knows her name - now is the time for them to come forward and help us solve a mystery and end three years of uncertainty for her family."
It is thought the woman, of Oriental appearance and aged between 20 and 40, may have been a visitor to the area and could have died up to three weeks before she was found.
An open verdict was recorded at her inquest in Skipton in May, after hearing there was no sign of a traumatic death or assault and the woman had not drowned.
She was not wearing walking gear and her footwear has never been found.
The woman was wearing a gold ring on the third finger of her left hand, which was made in Bangkok.
A funeral was held for her at Horton-in-Ribblesdale Parish Church earlier this month.
Det Insp Martin said: "The investigation has gone from the Yorkshire Dales to halfway round the world and we have learned so much about this lady and yet we still cannot tell how she came to be up on the hillside, how she met her end and, most poignant of all, just who she was."
