The autopsy also showed that the man's last meal was a pasty eaten three to four hours before death, but tests failed to reveal any foreign substance in the body. The pathologist, Dr. Dwyer, concluded: "I am quite convinced the death could not have been natural ... the poison I suggested was a barbiturate or a soluble hypnotic". Although poisoning remained a prime suspicion, the pasty was not believed to be the source of the poison. Other than that, the coroner was unable to reach a conclusion as to the man's identity, cause of death, or whether the man seen alive at Somerton Beach on the evening of 30 November was the same man, as nobody had seen his face at that time. The body was then embalmed on 10 December 1948 after the police were unable to get a positive identification. The police said this was the first time they knew that such action was needed.
