I find it kind of sad that someone who has the rage and wherewithal to make ricin and send it to the highest (debatable) levels of government can't come up with a better pen name than Fallen Angel. This guy really needs Jack the Ripper or, at the very least, Patricia Cornwell the Ripper as a consultant.

Also, FBI, it's really easy to find this guy. He's named after at least eight movies, most even made for TV. And there's even the surely brilliant SLIGHTLY FALLEN ANGEL. These are all valuable clues.

But perhaps none so much as the nude photography studio that comes up first of 1.4 million google references. This is definitely going to take professionals.
