Medical Murder

Dr Harold Shipman told his unsuspecting patients he was conducting blood tests as he injected them with a massive dose of heroin; they were dead within minutes.  Before his trial, many assumed he was an over-zealous GP who went too far in providing comfort to dying patients.  In the end, he was found guilty of deliberately and coldly murdering 218 of his patients.  But although Britan's worst serial killer, he is far from alone.
