A have a couple problems with this theory.
1. If LE could see James’ feet in the doorway while approaching the house, wouldn’t Jayme, or more importantly, the adult driver notice this as well?
2. As an adult, if I’m dropping a 13 year old off, I stick around to make sure she got in ok. If she went in the front door, she sees dad, freaks out and runs; I see and hear her. If I dropped her off at the garage, I’ve got a little ways to get back to the street. If there is commotion, I both hear and see this.
3. Yes, Perp could have heard her coming, been ready and subdued her as soon as she entered the house. If so, why did 911 hear a struggle and someone crying help?
I really think Jayme was there from the beginning.
You have some good points and thoughts. Question, if James was shot through the door, then the door was kicked open, how did his feet get in the doorway? JMO, but if someone is shot through a door, their body is now behind that door. When the Perp kicks it in, the body goes between the door and wall.
