Jack Frew murder trial: Teenager had 20 stab wounds Published on Monday 23 January 2012 14:30 Jack Frew, the teenager killed in a woodland area close to his school in East Kilbride, had 20 separate stab wounds, a court heard today. Mr Frew died on 6 May last year. He died from "sharp force injuries to his neck and chest," a pathologist told the High Court in Glasgow. As well as stab wounds to his neck and chest, Mr Frew had a 6.3in slash across the front of his neck, the court was told. Doctor Robert Ainsworth, who jointly compiled a post-mortem report on Jack's injuries, said at least three of the injuries - those to his neck, lungs and windpipe -would have been enough to kill the teenager on their own. He said the nature of the injuries were consistent with an attack with a knife. Craig Roy, 19, is on trial accused of murdering the teenager by repeatedly stabbing him on his head and neck with a knife. Roy denies the charge but David Burns QC, defending, said there was no dispute his client struck the teenager repeatedly with a knife. Doctor Ainsworth described the extensive injuries left on the teenager's body to the jury, and, reading from his post-mortem report added: "The post-mortem examination showed Jack had died of sharp force injuries to his neck and chest. He had sustained a large number of stab wounds - 20 in total. These injuries would have resulted in extensive haemorrhaging, from which he ultimately died. He said the extent of the blood loss from the wounds meant Jack's chances of surviving the attack would have been very low. He told the court: "Significant blood loss could occur in a few moments. It would require medical treatment to be there essentially on stand-by. It would be very unlikely that further medical treatment could have saved him. Doctor Ainsworth said when Jack's body arrived at Glasgow's city mortuary, his clothes were heavily bloodstained and there were slits on his T-shirt and hooded jacket. Jack's family left the room after the judge, Lord Doherty, warned them of the "descriptive" nature of the evidence they would hear. Roy sat with his head in his hands as the pathologist told the court about the injuries.
