I don't buy it.

So if he was in DC and he is the addict everyone from OM seems to be claiming, then why wouldn't he just call an escort service in DC? Instead he calls a service in Tampa, and then secretly goes to Florida to meet up with this girl(?), and then heads back home to Oxford? That doesn't add up.

There is always the possibility that he had a specific girl(?) in Tampa that he was carrying on with, but that would make the "pattern of behavior" narrative from Bjork seem flimsy.

Those hookers were for recruits folks.
