I'm going to play devil's advocate here, but it's possible that it could be the other way around... in regards to timing. I'm not accusing him, since I personally don't think that he's the murderer, but I can't just blindly trust someone without looking at all of the possibilities.

I have to doubt them before I can truly trust them. [ A shrug. ] But that's just my two cents on the matter. We don't really have much outside evidence to work on.
