The DNA of two men accused of murder was found on a floorboard at a flat where a businesswoman was allegedly tortured and killed, a court has heard.
Forensic scientist Nighean Stevenson said a sample taken from flooring at the West Kilbride home of David Parker, 38, contained DNA matching his profile and that of fellow accused Paul Smith, 47.
The pair, along with Colin Coats, 42, and Philip Wade, also 42, deny abducting Lynda Spence and holding her hostage for up to a fortnight before murdering her.
The financial adviser, 27, was last seen in Glasgow in April 2011 when she visited her mother on her birthday.
Ms Stevenson, from the Scottish Police Services Authority, examined the flat on Meadowfoot Road and took samples from floorboards in the loft conversion space where Ms Spence was allegedly bound to a chair, gagged and tortured.
