52 The forensic evidence as to the nature of the injuries was given by forensic pathologist Dr Ranson, who performed the autopsy upon the deceased, and by a forensic pathologist Dr Robertson, who was called to give evidence on behalf of Hong Bui. Dr Ranson described numerous cutting injuries to the body of the deceased. There were numerous recent injuries to the head and neck area of which ten such injuries were clearly cutting injuries. Dr Ranson gave evidence that significant force was required to cause a number of the head injuries, one of which included an incision through the left ear of the deceased severing cartilage and causing irregularity of the bone surface. Dr Ranson described a number of injuries to the chest area of the deceased including an incised stab wound which extended deeply into the tissue of the chest wall. He gave evidence of numerous injuries to the right upper arm of the deceased. In particular he observed a large injury to the deceased's right wrist penetrating the skin and into subcutaneous tissue. He said an injury of that nature would cause the severed blood vessel to bleed profusely as long as there was continuing blood pressure. He described further injury to the deceased including a gaping wound to the right shoulder which he said would have bled profusely. The left upper arm of the deceased was found to have a wound 11 centimetres in length which went deeply into underlying tissue. Dr Ranson stated that, if there was reasonable blood pressure, such a wound would bleed extensively. He also described a cutting injury on the mid part of the left upper arm of the deceased which passed through subcutaneous fatty tissue and muscle. That injury was consistent with having been caused by a sharp instrument and would have resulted in blood loss if there had been sufficient blood pressure left. A large incised injury to the left elbow of the deceased penetrated five centimetres into tissue. Dr Ranson said that small arteries and veins would almost certainly have been cut through by such an injury with resultant severe bleeding. A further serious injury was found almost separating the left hand of the deceased from the forearm. Major arteries run to the hand and, as most arteries and veins in that area were severed, that injury would, in the opinion of Dr Ranson, have bled profusely. A deep wound through tissue muscle and fat into the fibula was found in the left lower leg of the deceased. Dr Ranson said that that injury involved a high degree of force and incised substantial vascular elements, veins and arteries, which would have caused substantial blood loss given sufficient blood pressure. Likewise, a further incision found over the back of the left thigh of the deceased would have been the cause of significant bleeding. In total, Dr Ranson found 12 injuries to the deceased's head and neck area, eight injuries to the chest area, 15 injuries to the right upper limb, three separate injuries to the right shoulder, 14 injuries to the left upper arm, four areas of injury to the right lower limb and four areas of injury to the left lower limb. In addition he found a deep injury to the right buttock.
