13. Jimi Hendrix died in London in 1970, after chocking on his own vomit. According to the official story, the tragic death of famous musician was actually caused by sedatives he took that night. However, there are many conspiracy theorists who claim that Jimi was murdered. One of the most popular conspiracy theories is that Jimi was killed by FBI because he used to spread liberal beliefs among the young people, which was dangerous for the politics in the States. Scotland Yard even opened an inquiry over 20 years after his death, but nothing was concluded.
