Who Killed Diana?

I did read a lot of articles about the death of Diana. It includes loads of speculations about how she died and why she died. To me, I felt really sad about the death of Diana. Well, I do strongly agree that there were good things and bad things about the late Diana but surely you don't imagine finding a dead princess, right?

To me, I don't know. Princess Diana has been part of my live. It is really hard to realise that she is not there anymore. I just want to know whether it was merely a tragedy or was there a conspiracy behind it? I don't know. I think only those people who were involved on that day will only know. We don't know actually. Rest in peace Diana.
