British physician and suspected serial killer John Bodkin Adams was arrested in connection with the death of Edith Alice Morrell.

John Bodkin Adams
John Bodkin Adams was a British general practitioner, convicted fraudster, and suspected serial killer. Between 1946 and 1956, 163 of his patients died while in comas, which was deemed to be worthy of investigation. In addition, 132 out of 310 patients had left Adams money or items in their wills.
Death of Edith Alice Morrell
Edith Alice Morrell was a resident of Eastbourne, East Sussex, England, and patient of Dr John Bodkin Adams. Although Adams was acquitted in 1957 of her murder, the question of Adams' role in Morrell's death excited considerable interest at the time and continues to do so. This is partly because of negative pre-trial publicity which remains in the public record, partly because of the several dramatic incidents in the trial and partly as Adams declined to give evidence in his own defence. The trial featured in headlines around the world and was described at the time as "one of the greatest murder trials of all time" and "murder trial of the century". It was also described by the trial judge as unique because "the act of murder" had "to be proved by expert evidence." The trial also established the legal doctrine of double effect, where a doctor giving treatment with the aim of relieving pain may, as an unintentional result, shorten life.
