Back in May I posted this entry about a con artist I came across. He is nothing if not persistent, and he hasn't changed his M.O. For the latest update, along with the picture this clown is using, see my LiveJournal entry.
I don't know if it is possible to shut this guy down. If he has run off to Africa, regardless of the reason, he's probably unreachable. However, if he's still in America he can be found. There's a pic with the LJ entry.
Feel free to spam everyone you know with this info. Especially if they live in Houston.
