Of all the bizarre pieces of the ongoing hoo-haw investigation around former CIA director and general David Petraeus—who resigned last week after admitting to an extramarital affair with his biographer, Paula Broadwell—perhaps the strangest was the fact that an FBI agent, who had been one of the sources that broke the case, allegedly sent topless photos to Jill Kelley, the other other woman who incurred the wrath of Broadwell. Now, we know a little bit more about that FBI agent, Frederick W. Humphries II. "Fred is a passionate kind of guy," one former colleague told the Times. "He's kind of an obsessive type. If he locked his teeth onto something, he'd be a bulldog."

It seems that the 47-year-old Humphries was already friends with Kelley, the Tampa socialite and self-proclaimed military “social liaison” (whose self-proclaimed title was completely imaginary) prior to this debacle. Kelley came to Humphries to report that she was receiving harassing emails a few months ago; she told him she feared the sender was “stalking” Petraeus and General John R. Allen, the commander of NATO forces in Afghanistan. “She asks the agent, ‘What do you make of this?’ ” a spokesman for Kelley told the Times. “The agent said: ‘This is serious. They seem to know the comings and goings of a couple of generals.’ ”

When Humphries thought the case was being stalled, he brought it to Representative Dave Reichert, a Republican from Washington State, who then brought the information to House majority leader, Eric Cantor, who then brought it back to the FBI. But here's the thing: Humphries was never assigned to the case. The Times reports he was admonished by supervisors who thought he was trying to improperly insert himself into the investigation.

Lawrence Berger, the general counsel for the Federal Law Enforcement Officers Association, confirmed that Humphries never played a role in the investigation. But he was dogged in making sure the case didn't disappear—and the question is, was that because of a intrinsic obligation to justice, or an overly familiar relationship with Kelley?

To that end, there is the alleged topless photo that officials claim Humphries sent to Kelley at some time. Berger said Humphries and his wife had been “social friends with Ms. Kelley and her husband prior to the day she referred the matter to him. They always socialized and corresponded.” But he said the picture had nothing to do with this case:

“That picture was sent years before Ms. Kelley contacted him about this, and it was sent as part of a larger context of what I would call social relations in which the families would exchange numerous photos of each other,” Mr. Berger said.

The photo was sent as a joke, he said, and was of Mr. Humphries “posing with a couple of dummies.” Mr. Berger added that it was not sexual in nature.

So is Humphries covering up something inappropriate between himself and Kelley, or is the FBI/someone trying to make him look bad for continuing to pursue this investigation (and embarrassing a lot of people in the process)? All we know for sure is, we're a pair of spandex shorts away from a real life Burn After Reading.

Update: Well, will you look at that: The Seattle Times has gotten a hold of the shirtless Humphries picture. So now we know what that looks like.
