Two of the prosecution's main witnesses were Drs Keith Simpson and Eric Gardner, who testified on the second and third days of the trial respectively. Both pathologists testified as to the recovery of Wolfe's body—which they noted had been "covered, rather than buried"—and their subsequent examination of her remains, both in situ on the common, and—with regards to Dr. Simpson—at Guy's Hospital. With the aid of enlarged photographs of the wounds discovered upon Wolfe's skull, Dr. Simpson testified that only a knife such as that with the "peculiarities" of the one discovered hidden in the waste pipe at Witley barracks could have inflicted the distinctive circular wounds discovered upon Wolfe's skull. In relation to the partially extracted muscle tissue and ligaments discovered in the victim's right forearm and hand, Simpson confirmed such trauma could only have occurred through a distinctive, hooked blade retaining the tissue upon extraction.
