Mr Wright was found guilty of a Paisley murder after he left his victim, Mr McClelland, bleeding to death last July.
The victim was walking to his friends house to play computer games when he was stabbed in the heart twice by Mr Wright after he asked him for a light.
The co-accused who was said to be with Mr Wright at the time was cleared as the jury could not prove the charge against him an it was indicated that he was in fact not with Wright at the time he stabbed the victim. Lord Matthews stated that he committed an appalling murder on a decent family man for what appeared to be for no reason.
It was highlighted after the Trial by the prosecution that Mr Wight has a long list of previous convictions which includes possession of knives. Mr Wright will be sentenced at the start of July but is expected to receive a life sentence.
