A Scots man who murdered a teenage boy after by stabbing him through the heart has died in prison.
Francis Docherty, aged 57, of Bogany Terrace in Castlemilk, Glasgow was found guilty of killing David Ferns.
He was sentenced to life at the High Court in Glasgow on Wednesday, August 12, 1987.
Docherty had been arguing with the 16-year-old's older brother when the pair were out walking their dogs.
David, of Stravanan Road, also in Castlemilk, arrived to help his sibling during the argument between them.
However, he was then fatally stabbed through his heart by Docherty.
Docherty was reported missing from at HMP Edinburgh, then known as Saughton Prison, on Thursday, October 21, 2004.
Prison staff had raised the alarm after the then 40-year-old had failed to return from a work placement at a charity shop.
