Except his phone and truck data put him outside well before he claimed he woke up to his alarm at 4:30.
When confronted with evidence that his alarm was not set, Barry eventually claimed to have woken up on his own.
There's just no way he slept, much less took the time to take a shower. I believe he did both in the hotel room.
You raise an interesting point. If he disposed of her remains overnight, did he ever enter the house again?
I believe he did remove the Bobcat around 4 am (the dog hits and footprints) but did he risk entering the house and leaving traces?
I pegged him for showering after he did what he did -- and to keep his truck pristine (dirty but clean of murder).
Maybe that's what he was doing the night before, just as he said, loading up his truck. Including the first spare outfit. Because he knew, once he left PP to go dispose of his wife, he wouldn't be going back into the house!
I wonder what he used to make sure none of his "trash" left any trace in his truck. The coolers? Tarps? Blankets? Towels?
Returns to PP at dark thirty, uses the Bobcat to unhitch the trailer, strips down right there at his truck and dresses in the first of several wardrobe changes....
