The DNA of murder accused Ross Monaghan was found on one of the guns used to shoot gangland figure Kevin 'Gerbil' Carroll to death, his trial has heard. <\/p>\n
Forensic scientist Pauline McSorley told jurors the chance of the DNA belonging to anyone other than Mr Monaghan was one in a billion. <\/p>\n
But the High Court in Glasgow heard the DNA of a laboratory technician was also found on the weapon. <\/p>\n
Mr Monaghan denies murdering Mr Carroll in an Asda car park in January 2010. <\/p>\n
The court heard that the gun - a black self-loading pistol - was found alongside a revolver behind Coatbridge Library on 26 January 2010. <\/p>\n
Mr Carroll, 29, had been shot dead 13 days earlier at an Asda car park in the Robroyston area of Glasgow. <\/p>\n
Giving evidence to the trial, Ms McSorley told advocate depute Iain McSporran, prosecuting, that the gun was swabbed and they found DNA from \"at least three people.\" <\/p>\n
It's horrendous that should have happened from a scientific point of view <\/p>\n
She said the major source of the DNA was 30-year-old Mr Monaghan, and described it as a \"perfect match\". <\/p>\n<\/p>\n
