Yes. I thought they knew that because there was something on his phone, because she had been placed in the car earlier, or she had obvious injuries.
I was in favor of the second option, but the last would be a strong possibility as well. If blunt force trauma is true, then that conclusion now makes sense.
What doesn’t make sense is the following:
If she was alive when they got to the car in the 7 o’clock hour, then the dumping of the backpack would be a sign of premeditation.
But why do it like this?
I’m not sure what I think happened at this point.
