The biggest thing that bothers me about the surveillance video is that she didn't mention it to LE. IIRC, it was the store who contacted LE (is that right?). I feel confident that LE asked her repeatedly to recount that day for them. Go through it again. Ok, now go through it again. Just in case a little something is mentioned that might have been forgotten the first (second or third) time. This, however, is not something little! I have a hard time believing she forgot she went to the store that day. But, why on earth would she not tell them this info? It looks pretty innocuous to me. I just don't get it.
