Sir Bernard Spilsbury followed Cherrill into the witness box to testify as to the autopsy he had conducted upon Oatley's body. Spilsbury testified the cause of death of the decedent had been the deep cut to her throat, that Oatley would have bled to death in less than five minutes, and that death had occurred at approximately 12:30 a.m. on the morning of the discovery of her body, although the actual time of her death could have been up to two hours before or after this time.
