Homes "up north," which this sort of is, often are homeowner projects. I doubt the front door was hollow, but it might not have been the best quality. Was the door battered, or was the lock kicked in, meaning the killer knew how to kick in a door (kick the lock). It would be interesting to see a photo of the door, which could indicate military experience. From the battering of the door scenario the killer must have been younger and, most likely, wore hard soled shoes. Why not try to get into the house quietly? Vendetta or hired hit?i have been thinking of motive as we all have.
Someone posted that dad went to the door because he heard it being kicked in and was shot. That makes sense.
So to me that says dad was not the target. He is dead. Finished , Move on.
There were pictures of the kicked in door in a precious thread. The frame was not splintered. It was the door that was cracked and the door appeared to be at least two i ches thick. Think of how strong a kick it would take to crack a thick wooden door.
Perhaps others think kicking in a door is easy. I would think that in order for someone to think this is a good method, there would have to ve practice. Perhaps this method has been used before.
Mamy people have hollow core doors in their home which are easy to punch in. The exterior door is not like the doors many people have in their homes.
So what was the point of the home invasion?
In such a rural area the killer could have parked anywhere without creating attention. You just pretty much keep to yourself, and people don't ask.
