Maura Murray & Butch Atwood the Bus Driver- Was he a Suspect

We just watched the series. We would place our bets on BUTCH ATWOOD.

1. He was last to see her, that anyone knows.
2. He says she was vulnerable, had been drinking. Therefore, he knows she is vulnerable.
3. He had the opportunity, not once, but twice. SUPPOSEDLY at accident scene, and then possibly at point of dog scent, in front of his house.
4. In one episode, the state trooper said he went one way to look for her, and atwood and his bus went the other way, "toward the lakes region".
5. Atwood injected himself in to the search.
6. Was she ever on the bus? Was bus searched? He has place to hide her, away from wife and her mom.
7. Atwood, volunteered Mauras refusal, and himself going to call police. In one statement, he takes himself out of the picture, and puts the white hat on............SUSPICICOUS.
8. Told his wife, after calling police, that he was going out to bus to do paperwork? WTF? Why?
9. Cop says, "I did not know atwood before"....why volunteer?
1o. Atwood, is HIDING IN PLAIN SIGHT..........fat burly bus driver, that no one suspects...............IT WAS HIM.
