The family of Ann Ballantine have said they may "never get closure" on her murder, over 30 years after the harrowing case.
One of Edinburgh's most notorious cold cases, the 20-year-old was discovered in the Union Canal after vanishing months earlier.
Last seen by her mother on November 18, 1986, Ann's body was found decomposed in February 1987, with the family still yet to see her killer brought to justice.

Sparking a huge investigation, police eventually came up with a suspect and sent a report to the procurator fiscal, but they found there was insufficient evidence for a prosecution.
Speaking to Edinburgh Live this week, Ann's brother Alan said he feels nothing will change with the case and that a conviction will never arrive.
He said: "There has been no updates or anything for a while.
"In my opinion nothing will ever happen now, it's difficult but I think we will never get closure on what happened.

"There has been other cases over the years where people have been convicted on all circumstantial evidence, but in our case we were told we couldn't go to trial with that.
"That was like a dagger in our hearts hearing that."
At the time she was discovered, many had believed Ann had been the victim of a serial killer, due to the length of time she was believed to have been stored before being put in the canal.
However, her mother Isobel has previously shared that the family believe they know who the individual was that committed the devastating crime.
Speaking in 2017, Isobel had said: "It's difficult knowing he's about, it makes my blood boil."
"It was like living in a nightmare from which we couldn't wake up.
"When they found her body in the canal, they asked me if I could remember whether she had a scar on her head.
"I told them I'd had three kids and I really couldn't remember so my friend and family hairdresser helped identify the body.
"We never got to see her one last time, which is a killer. Most people get to see the body or kiss the body if they want to. We never got that chance.
"The body was so decomposed, we never got to say goodbye."
Ann was described as a kind young woman who spent her time doing volunteer work with disabled and disadvantaged young people at Canongate Youth Project in Edinburgh.
Living on Dalry Road, she had moved out of her family home with mum Isobel and dad Graham at the age of 18 to gain her own independence.
Speaking previously, Isobel had added: "He's probably with his family and Ann is six-feet under. Why does he deserve that? I'm very bitter.
"Ann was my first-born and I was only 18 but she was a good baby. She was such a happy child - a real happy-go-lucky kid."
