 Dr Douthwaite also initially endorsed Hannam's theory that morphia and heroin would have turned Mrs Morrell into an addict and given Adams complete ascendancy over her.Hewett's quoted view that there was no evidence to present before a jury, as Mrs Morrell's body had been cremated shows a misunderstanding of the principle of corpus delicti, and his assertion that traces of drugs found in exhumed remains of two other patients of Adams made better cases against Adams lacks confirmation.The advanced state of decomposition of the first corpse prevented the establishment either a definite cause of death or the presence of drugs, and the examination of the second concluded the causes of death were coronary thrombosis and bronchopneumonia, and the small amounts of morphine and barbiturates found were insufficient to draw any firm conclusion.
