From what I'm reading elsewhere, no, it seems as if he's been in the area, very involved at the Lutheran church (which apparently has a 't' in the logo that resembles the T in BTK that was on the recent cereal box message thing) and several people are accounting for many years of having lived near him (or visiting relatives who do and can't speak now) in that neighborhood and another nearby...so I'm guessing not. But like I said, that's all based on things I've read elsewhere.
From the news conference this AM, there is going to be tight control of the information about the killer, methods, etc. until after the trial. We'll know soon enough, though, as it's sure to be a book-and-movie deal for somebody.
