There was no video. I believe that MR purposefully saved the receipt from the McDonald's visit to show to LE as a means of corroborating that Dylan did make it at least as far as to McDonalds's (after the Wal-Mart visit). I recall that MR's comment to LE was something to the effect of: "I couldn't have eaten the entire order myself." And I do believe you are right about the Drive-Thru order, as Dylan was anxious to eat in the car while they made their way back to the cabin. He was hopeful that MR would allow him to be dropped off at a friend's that very night. But, according to MR, he nixed that idea telling Dylan that it was rude to impose on someone and their family that late in the evening. (Well, MR, was it not beyond rude to . . . never mind.) As if the proof that Dylan was with him when he stopped at McDonald's would be important in establishing MR's credibility later when it was called into question. That, coupled with the receipt from Wal-Mart, was the beginning of his paper trail that he thought would serve as a basis to exonerate him in establishing precisely when Dylan disappeared and under whose nose. I mean, MR was out and about running his many errands when Dylan went missing. It couldn't have been his fault. He neither saw nor heard anything as he wasn't even home at the time!
MR did pointedly say that he had attempted to call Dylan on Dylan's cell phone, and also on his own land line at his cabin -- but mysteriously enough, there was no answer! So, he could not make concrete plans for Thanksgiving without Dylan's input as to where he wanted to spend Thanksgiving -- perhaps with MR's brother's family in/near Castle Rock, CO, or did Dylan wish to spend it at MR's cabin? It was all about Dylan, you know. (Please excuse me, I think I am going to be ill.) Somewhat of a flimsy alibi, but nonetheless one that he purported to offer in good faith. I can imagine him saying: "Oh, I saved the receipt not because I knew I would be needing it later, but because in my line of work, I am used to saving receipts for tax purposes." Blah, blah, blah, good sociopathological-speak 101 for establishing an alibi. (I don't have any links as I picked up a lot of this from podcasts and some of it sticks indelibly in my memory.) So, feel free to remove any and all that doesn't pass muster. I am thoroughly disgusted and will absent myself from this particular thread as a self-time-out.
