John Docherty in court over Elaine Doyle death in Greenock

Elaine was last seen alive after leaving a disco in Greenock

A man accused of murdering a teenager more than 27 years ago has made his first public appearance in court.

John Docherty, 49, denies strangling and killing 16-year-old Elaine Doyle in Greenock in June 1986.

He has lodged special defences of alibi and incrimination. The trial is due to start on 25 March at the High Court in Edinburgh.

This is the first case to come to trial following an investigation by the Crown Office's cold case unit.

It was set up to look at unsolved murders across the country.

Elaine Doyle, 16, died on her way home from a disco in Greenock, Inverclyde, on 1 June, 1986. Her body was found the next day in a lane off Ardgowan Street.

Mr Docherty was arrested last year after a police operation in Greenock, which followed renewed appeals about the case, including one on the BBC's Crimewatch programme.
