Harold Shipman was a British serial killed who like Graham Young poisoned his victims but unlike Young Shipman used morphine to poison his victims the same chemical used to make heroin. In his early years he started to suffer blackouts and told his colleagues he had been suffering from epilepsy. In fact he had been forging prescriptions to get the drug pethidine. When his addiction was discovered he was sent to a drug rehabilitation centre and he lost his job. He also went down as one of the most profilic serial killers in history and able to get away with it by chaging a patients medical records after he killed them. Eventually he was found guilty and sent to Frankland before being transferred to Wakefield. In 2004 he hung himself in his cell and was formally declared dead at 8.04 am on the day of his death.
