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.
