A killer who murdered a disabled man in his own home after leaving him bound and gagged was facing a life sentence.

Mark McConville, 39, attacked William Duncan at his flat in Glenalmond Street in the Shettleston area of Glasgow and struck him on the neck with a knife.

McConville trussed his victim with ligatures tied around his wrists, and arms and stuck a sock into his mouth which was secured with a further ligature.

The killer also put a pillow over his head as the victim's breathing was restricted and he asphyxiated and died.

The fatal attack occurred between January 21 and February 3 last year.

McConville had denied murdering Mr Duncan, 55, but was convicted of the offence by a majority decision of a jury at the High Court in Edinburgh.

Following the verdict defence counsel Tony Lenehan KC said the sentence for murder was fixed as life imprisonment but the trial judge, Lord Armstrong, would require to set a minimum term that McConville must serve, known as a punishment part.

The court heard that police had forced entry to the home of Mr Duncan, who used crutches after a leg amputation, on February 3 last year.

The murder victim was lying face down on a bed with his wrists bound with shoe or boot laces. His arms were trussed also with a cable and a cord was around his neck. He also had a pillow on his head.

Officers found no signs of a disturbance but saw a pair of crutches in the living room at the property. The court heard that a wet and blood stained sock was found in the victim's mouth which had been used as a gag.

An 11 cm long wound was found to his neck but was regarded as a superficial injury which did not play a part in the victim's death.

Pathologists concluded that the victim died because of the gagging inflicted on him during the attack at his home.

DNA from McConville was found on Mr Duncan's top which could have been caused by him picking up or dragging the victim. It was also discovered on laces used to truss him up and on the pillow.

Advocate depute Colin Edward told jurors that we may not know why McConville murdered Mr Duncan but that evidence pointed overwhelmingly to him committing the crime.

The court heard that McConville has a criminal record but not for offences of violence.

Lord Armstrong deferred sentence on McConville, a prisoner in Glasgow's Barlinnie jail, for the preparation of a background report. He is due to be sentenced on July 20 at the High Court in Glasgow.
