It is complicated. The complication I have in mind has to do with entering the garage.
I suggested earlier the perps removed the garage door opener from the parked van at the airport, then went back to the S house etc. . They would still return the opener to the parked van. But how would they access the van without tripping the car alarm?
Then I suggested they may have taken the whole van, in case there was no removable garage opener in the vehicle, but a programmed code or home link system. They would then have returned the van. Without a key?
Okay, then they do not go to the airport, they wait for Dr S to return home, she opens up the garage door, they sneak in. However, that only works if the garage door is linked to a security system that disarms the alarm as well as the outside surveillance cameras in front of the house. If they are still running, we are out of luck. Nope, we are not..
Here is my theory: They will have to make sure Dr S disarms the alarm system herself. Even if they had a code, they would have not done so themselves. It would have clearly implicate a family member or a person, who had knowledge, like possibly CWW.
Having said that, they made a mistake I was pointing out from the very beginning. In an effort not to draw attention towards the fact that Dr Sievers was targeted, they staged the break-in of the garage side door. That door had to be part of the alarm perimeter, since the police would have known how they came in. Also, in talking to several home security experts, they all agreed that the garage side door is always included in the system in these kind of homes, because it is so vulnerable. The main garage door is usually not part of the alarm system, but can be on request.
We were wondering - and so was LE - why the motion detectors did not pick up any movements and how the intruders knew to break into a non-secured (cameras) side door. Here is why: Someone TURNED the security camera, which is located over the garage, into the other direction. If you look at that camera, there is just enough space that would allow the camera to be repositioned!
So what happened here is exactly the opposite of what we expected. The camera was focusing on the area towards the side door. That door was staged AFTERWARDS, when the alarm had been turned off, after the attack. They then repositioned the camera again later.
I have to find one of the first news coverages, where you can see a turned or fallen trash can in exactly that area! I always wondered why it was turned over. That was not the can on the curb.
So, that is what I think happened. The question remains, when was the camera repositioned the first time, if this is what happened.
All my copyrighted opinion of course.;--)
