She died of toxic shock syndrome. Unfortunately, this is a VERY RARE occurrence from using a tampon.
I don't think most people commenting read the Daily Mail article, instead they jumped right to conspiracies.

Being an Air Force cadet - I mean being that active - she was probably using tampons. Unfortunately, it's a very sad, tragic death, because her condition was not caught in time. She should've gone to the E.R.
Many years ago, I worked in the ER (not as a doctor, lol) and I remember we had a case of a college girl who had symptoms of shock. It ended up being TSS from using a tampon. The college girl was lucky that the ER doctor diagnosed her in time.
