That stands out to me too. Jumping off your post. He smokes a cigar at midnight the night his wife is murdered. The cameras just happened to have been messed with that same night/early morn.
He doesn't use the door with the easy entry with the card key instead uses an emergency door (which could have had a silent alarm, I know cause I accidently set one off once going for a smoke :blushing

. Then throw in the clean downstairs at the house, CY left unharmed.... Doesn't look good for him so far. If he doesn't testify I will watch the first trial to see what I missed.
