Barnaby Jack was a famous hacker, he died in San Francisco on July 2013 just a week before he was due to illustrate the method for hacking implanted heart devices from 30 feet away. He was scheduled to demonstrate the possibility to deliver a lethal electric jolt to the victim. The San Francisco Medical Examiners office conducted the autopsy on Friday. The report states that there was evidence of tobacco, alcohol, and illicit drug use surrounding the body. The only thing that makes sense is that a young man flew away, talk of conspiracies have no foundations.”]
