The purpose of the cameras are to protect the driver, if he knew where they were present or where they were located he could have moved the vehicle so it would not catch his activity.
It is a rural rural area. His delivery time would have been similar, after she was home from school. He likely had seen her before- this was likely premeditated.
What was the length of the driveway?
Where did he leave the package?
In rural areas it is common to have a large mailbox near the road where deliveries are to be made. Unless it was a big package and he had to drive up the driveway? I would be curious to know the length of the driveway from the road, and where he parked his truck typically for deliveries.
In my opinion only,
