The main suspect, Francis Auld, was tried for murder in the High Court of Justiciary in Glasgow and was acquitted when the jury returned a majority verdict of "not proven".
[3] Duffy, a 19-year-old student at Motherwell College, went missing in the early hours of Saturday 30 May 1992 after a night out with friends, celebrating the fact she had been called to audition at the Royal Scottish Academy of Music and Drama.
[4] Her body was found that evening in an area of waste ground near a car park at Miller Street, Hamilton, South Lanarkshire.
Duffy was found "lying on her back, naked from the waist down, with her face and head covered in blood" and branches and twigs "had been inserted into her mouth, nostrils and vagina".
MP John Home Robertson, in a 1995 bid to scrap the verdict, praised "Kathleen and Joe Duffy for the thoughtful and constructive campaign that they have been waging".
[13] Jim Govan, the chief forensic scientist at the original trial, then went on public record, saying the jury got the verdict wrong and there was more than enough evidence to convict.
