Having carefully reconstructed the skull by wiring together all 38 fragments that could be found, Simpson clearly revealed a large impact site at the rear of the skull measuring five inches in length and one-and-three-quarter inches in breadth, further affirming his earlier conclusions at the crime scene. This injury, coupled with a fracture to the victim's right cheek bone, led Simpson to conclude that the victim had died as a result of a single, heavy blow to back of the head, inflicted while the victim was lying face down. The weapon which had delivered this fatal injury was a pole or bough of wood, and the blow from this weapon had caved in the skull. The commensurate positioning of the fracture to the cheek bone further supported the conclusion the victim had been killed as she lay face down on the ground. These injuries would have induced rapid unconsciousness, and death would have resulted within minutes.
