Is convict innocent of double murder?
Andrew Cameron has spent 11 years in jail for killing teenagers Kay Wyllie and Nancy Nicol.
Cameron, 30, has always protested his innocence.
Now his lawyer wants a new inquiry because, he says the two murders bear astonishing similarities to that of panto schoolgirl Mhairi Julyan.
Glasgow solicitor, Joe Beltrami, said yesterday it was extremely disturbing that "a possibly innocent man has been locked up for years for being wrongly convicted of two murders."
Sex fiend Gavin McGuire was last week jailed for 30 years for strangling Mhairi, 16. The jury heard how she was killed as she walked home after a night out with chums at a Christmas pantomime in Kilmarnock.
McGuire, 37, had a string of convictions for rape, attempted rape and other sex offences stretching back 20 years.
Mr Beltrami said attacks for which Cameron was jailed and those linked to McGuire were very alike.
He is to ask for DNA tests on samples from the three killings.
And he said there were amazing similarities between the murders of Kay, 19, and Nancy,18, and the unsolved killing of Elaine Doyle, 16.
Detectives have revealed they are to question McGuire in prison about Elaine's murder. Cameron was in jail at the time of her death.
The girls, killed between 1984 and 1986, were from the same area as Mhairi - Kay, from Ayr, Nancy, from Kilmarnock, and Elaine, from Greenock.
All were "ferociously strangled" Mr Beltrami said: "The similarities are astonishing"
