I’m pretty flabbergasted with the recent revelations of developments in the investigation of the anthrax mailings that killed five and infected 22. The FBI is saying now that the case is closed, that they feel they could have proven Bruce Ivins’ guilt, and that they believe he was the only person responsible for the attacks.

Back in 2006 I wrote a piece on the lingering mystery surrounding the attacks:

I can’t help but wonder if this guy had help from powerful friends — maybe a foreign-intelligence service. This is entirely speculation. If somebody wants to offer forth evidence pointing to Joe Scientist with an Axe to Grind, I’ll hear ‘em out (but really, the FBI’s the one who needs to hear it).
But could Joe Scientist with an Axe to Grind to pull off, arguably, the biggest unsolved crime in the last half century? To outwit everybody at the FBI, the intelligence community, every cop, and amateur sleuth?
I’m skeptical. It strikes me as beyond the capacity of an ordinary crook, pulling this stunt for the first time. The 9/11 hijackers, perpetrators of the worst terrorist attack in U.S. history, left behind tons of evidence.
But that leaves us wondering out loud if the person had help from a hostile foreign government. There’s no direct evidence of that, but just… it makes a bit more sense than the Lone Nut or Lone Evil Genius theories.
This Theoretical Hostile Foreign Government would only have needed to send one person, if they were trained well enough. In November 2001, after the last mailing, he could fly from Philadelphia or Newark or New York to Islamabad or Tehran or Baghdad or wherever never to be seen again. Or it could be a government’s intelligence service, operating without orders from their leaders.

It appears, if the FBI is right, that it was Joe Scientist with an Axe to Grind, and/or mental issues. Baffling and horrifying that the source of the worst bioterror attack on American soil could be one of our own.
