BLOOD was found on the boot of a man accused of murdering a man in his flat, a trial has heard.
Forensic scientists matched DNA from victim Lee Duncan, 31, to a bloodstain found on the tread of a shoe confiscated by police from Gary Parker.
Officers seized the boot from Parker, 45, the day after Mr Duncan was discovered dead in the bedroom of his Tollcross home.
Experts also extracted DNA samples from saliva on two cannabis joints recovered in the bedroom which matched both Parker and Mr Duncan.
But the High Court in Edinburgh yesterday heard that blood from another man was found on a Rangers towel in the flat while DNA from at least two more people was found on joints left in the bedroom.
Forensic biologist Kirsty McTurk gave evidence about the examination she conducted at the Lauriston Place flat.
She told the court that a bloodstain found on the sole of Parker’s right boot contained DNA with a certainty of one-in-a-billion that it was not related to Mr Duncan.
Reading from her forensic report, Ms McTurk said: “In our opinion, the location of the blood-staining provides support for the wearer having stepped in Lee Duncan’s wet blood.”
Her report said that two of the joints found in the bedroom were consistent with “Gary Parker having smoked and Lee Duncan having smoked and/or handled the cigarette”. Saliva from a man and woman, who were also identified by police, were found on other joints.
Ms McTurk said that blood found on the wall, pillow, headboard and duvet was “consistent with Lee Duncan having been assaulted whilst lying/sitting on the left side of the bed”. She added that blood found on a towel in the bathroom belonged to Mr Duncan, his girlfriend Kirsty Nelson, 33, and a third man who was identified through the national DNA criminal database.
The report concluded that the scientific findings “did not help to identify who attacked Lee Duncan”.
Earlier, the trial heard from Jane Officer, a forensic scientist for the Scottish Police Authority. She told the jury that blood tests found traces of methadone, cocaine, cannabis, diazepam and possibly temazepam in Mr Duncan’s body. She said the amount of methadone has been “associated in the past with toxic or fatal doses”.
Parker denies murdering his friend and neighbour by repeatedly hitting him with a claw hammer and compressing his neck with a belt or cable on February 24, 2011. Parker has lodged papers blaming two other men for the murder. The trial continues.
