sorry Zool... I should have referenced it. In cross of Groffy, Day 10 Page 64.
Q. It was locked or unlocked?
A. The driver's door was unlocked when I got there.
Q. Okay. The other doors were locked?
A. Yes, the other doors were locked.
Q. And that would be actually four more doors, correct, including the rear?
A. That's correct, four doors.
Q. Now, if I understand, what you did was, by opening the driver's side door, you were able to sort of reach over and, with your gloves, unlock the front passenger side door first, right?
A. That's correct, I did that.
Q. And then from that location, that position on either side, front and passenger, you were able to easily reach around and unlock the rear driver and passenger side doors.
A. That's correct, I unlocked those doors.
Q. And then you were able to open all four of those doors, wide open, for taking pictures and what not?
A. That is absolutely correct.
You can continue on reading from there, but it is never clarified how that rear door was open although Buting says 4 more doors including the rear.... well that rear door doesn't just magically open from the inside. What I did gather is.... not all of those pictures were taken on the same day, and somewhere in one of these threads I actually figured out what pics were taken on what day. But I think it is fairly certain that they had that rear cargo door open on the 6th of November, at the latest the 7th. Why? because we know they did presumptive blood tests back there, the spatter on the inside door, TH's blood, etc.
