No I don't think your statement was a tin-foil one. I think he was attempting to "set" his alibi. Same way Scott Peterson thought he could do it. He phoned his wife's cell which had been dead for weeks and left a message that he was coming home from the Marina from fishing. Barf!
You're exactly right, Canadian. It's the same arrogant behavior that Peterson used when trying to cover-up what he did to Laci.
