Death by aliens?

So I regularly listen to the How Stuff Works podcast, "Stuff You Should Know." While the hosts annoy me for some reaosn or another, they always have interesting ideas. Well, I listened to one episode today and, I have to say, what they shared was just bizarre. Strange enough to make me think there's a story in there somewhere.

But maybe not. Who knows? Whatever the case, I now share with you the most bizarre series of deaths I have ever heard about: Death by an unknown cause.

Anyone have any ideas?
