2 Dr Harold Shipman

Dr. Harold Fredrick Shipman was an English doctor and is one of the world’s most prolific serial killers in recorded history, proven to have been responsible for up 250 murders. A trusted doctor, he was well respected in his community, however colleagues and local undertakers began raising concerns over the high death rate in the area and the large number of cremation forms for elderly women that he had countersigned. Several bodies were later exhumed and post mortems revealed diamorphine within their system. It was later established Shipman had purposely injected fatal doses of the drug in a huge number of patients, causing their death. He then forged their wills so he could inherit large sums of money and completed cremation requests to destroy the victim’s bodies. The trial judge sentenced him to 15 consecutive life sentences and recommended that he never be released. Shipman later hanged himself in January 2004 in his cell at Wakefield Prison.
