WITNESS in the Kevin 'Gerbil' Carroll murder trial today told how she feared she was caught up in "another Dunblane massacre" when the gangster was shot dead in a supermarket car park. Witness Emma Busby, 32, a chef in a care home, said she was aware of a baby crying near her as she saw a hooded man jump out of the front passenger seat of a car holding a gun in his left hand. She was giving evidence at the trial of Ross Monaghan, 30, who denies repeatedly shooting and murdering the gangland figure while acting with others, outside an Asda store in Robroyston, Glasgow on January 13, 2010. He has launched a special defence of incrimination, blaming a man who cannot be named for legal reasons and seven others. At the High Court in Glasgow today, Mrs Busby said she was shopping with her mother and was making her way to her car when a dark-coloured vehicle pulled up, blocking in a black car. She said she saw a man get out with a silver "Clint Eastwood" or "cowboy" style gun and she retreated with her trolley back towards the supermarket where her mother was still inside buying cigarettes. Mrs Busby told the court she heard two different types of gunshots, one making a "bang" sound while the other was more of a "crackle". She said: "My first thought was that someone had just come to shoot up the general public. I thought it might be another Dunblane massacre." Mrs Busby agreed with advocate depute Iain McSporran that she believed "anyone and everyone" could have been shot. Jason McConnell, 22, told the court he had been watching out for his friend Steven Glen from the Asda cafe. The jury previously heard Mr Glen had a meeting with Carroll in the car park moments before he was shot dead. Mr McConnell denied being a "spotter" for the shooting and said he was only there to let Mr Glen's parents know if something happened to him. He said his friend was "nervous" about meeting Carroll because of things he might have heard. The court heard a suggestion that people who had been taken away by Carroll sometimes referred to it as "an alien abduction". Monaghan's defence QC, Derek Ogg, put it to the witness there were stories of people who had been taken away by Carroll who were found in an "extremely distressed or damaged state". He asked if he thought his friend had thought it could be something like that. Mr McConnell replied: "Maybe." Mr Ogg asked: "He was terrified wasn't he?" The witness said: "Yes." The court also heard from Allan Johnston, 30, who said Mr Glen had phoned him from the scene of the shooting to say: "Your pal's dead." He was asked by Mr McSporran if he knew of anyone who might have an interest in having Carroll killed, to which he agreed. Mr Ogg asked: "More than one name?" Mr Johnston said: "Yes, probably." Monaghan is also alleged to have attempted to defeat the ends of justice by concealing a revolver, a pistol and ammunition under bricks and undergrowth in Academy Street, Coatbridge and setting fire to a car. He is further charged with possessing guns and ammunition without a proper certificate. Monaghan denies all the charges against him.
