Murder detectives have released images of four rings that could prove vital in identifying a woman whose dismembered remains were found in a shallow grave.
Police are appealing to the public to help solve the mystery of the body, discovered by a cyclist on Corstorphine Hill, Edinburgh, on June 6.
Around 80 calls have been followed up but no breakthrough made, investigators said.
They believe the woman’s distinctive gold rings could hold the key to establishing her identity.
Detective Chief Inspector Keith Hardie said: “Responses to previous appeals for information on this woman’s identity have been encouraging and, while we are following up calls and information from all over the UK, we have still to make a real breakthrough in identifying the victim.”
He said of the rings she was wearing: “Two are particularly distinctive: one in the shape of a daisy and one in the shape of a heart. Both are gold and are set with precious stones.
“I would ask anyone who recognises these rings, or who has seen someone they know wearing rings like these, to add that detail to the other things we know about the woman.”
The victim was white, aged between 32 and 60, about 5ft 2in and of medium build. She had had extensive work done to her teeth, including veneers and implants.
Mr Hardie added: “We have followed up more than 80 calls and, while we are extremely grateful for the information, we still await that real gateway call.
“We are keeping an open mind on this woman’s background and history but I am determined to uncover the information that will enable us to identify the victim and then identify those responsible for her murder.”
The heart-shaped gold ring is thought to be an Irish claddagh ring.
Police believe it is possible part of that ring is missing, since claddagh rings also tend to feature a crown design, or something similar.
Mr Hardie said: “As time goes on, it becomes more and more concerning that we haven’t got a name for the lady. It would make perfect sense and be proportionate to widen the net and look further afield,” he told a news conference at police headquarters in Edinburgh.
