 They quoted the Coroner's observations about the cause of death and that the "consensus of medical opinion was that severe compressive force applied to the upper abdomen, or possibly the lower chest, or both together, was required to have caused this injury", and that "medical witnesses were asked to consider whether the application of a knee or an elbow, whilst [the deceased] was on the hard flat surface, either during or separate to the fall could have caused the mechanism of injury.This was accepted as a possible means by which the injury could have occurred".
