There did seem to be some random emphasis going on in that article (not just with italics but with bold text too). It was a little distracting in places (maybe just because I'm dyslexic?) but the article was fascinating enough to keep me reading.

I was a little disappointed that the article ended with speculation though. Given the title, I was expecting something more concrete. But I guess I should be grateful that the author didn't feel the need to sensationalise the truth for the sake of narrative (like so many reporters do these days).
