DrDevil writes "Barnaby Jack, the computer security expert who died mysteriously a few days before he was due to give a presentation on hacking pacemakers at last year's Black Hat, died of a drug overdose. The coroner initially withheld the report, which led to much speculation given the timing of his death. Mr. Jack appears to have taken a cocktail of drugs (PDF) and was found dead by his girlfriend. His girlfriend stated that he had used drugs regularly."
