Another thing I find weird, perhaps someone can enlighten me. The cleaning lady and physical therapist person got to the home approx the same time on that Friday morning the bodies were discovered? The cleaning lady used her key, but said the alarm was off. Didn't both the cleaning lady and the therapist know/expect that both Shermans were at home? They were apparently scheduled for their usual exercise/whatever therapy, so why would they not be home, or be expected to be home? H's vehicle was parked in its normal spot, so even more evidence that they'd be, or at least she would be, at home. So why, if they were home, or expected to be home, would the cleaning lady have expected to turn OFF the alarm... why would the alarm be ON while the occupants are presumably moving around inside the home? IIRC, the cleaning lady said something to the effect of - it struck her as odd because the alarm wasn't on and she therefore didn't need to turn it off... which leads one to believe that normally, the occupants would be indeed home for their appointments with whichever therapist, but yet the alarm would be on. And then at the same time, we've been told from the start that the Sherman's didn't believe in security, nor locking doors etc. So what's with the alarm being set while they are at home?
