He had the marina receipt for the 24th so it really doesn't matter...they consider it legit....probably have a record of it at Big 5
Well, there's another thing. This kind of reminds me of those English mystery stories, where they say things like, "He remembered to wipe his feet, so as not to soil the carpet, as he dragged the body into the house." This attention to small details. I mean, if we assume that his real only purpose in going out "fishing" was to dump the evidence of his MURDER, then why was he so careful to be all "legal" about everything?
I mean, a ticket for fishing without a license would have been just as good a proof that he was out there, as a license would.
