I suspect that the mustang was in the garage all the time that he was home and the van was parked behind it until it was towed away. That may be why we never saw the mustang until Wednesday of last week. He may have stashed supplies in the trunk. Then, reportedly drove the mustang to the park where his parents scooped it up late Tuesday or early Wednesday. Also, if it is true that an empty gun case was found in the mustang by LE after it had been returned to the driveway, his parents certainly saw it and knew that he had the gun. They may not have known that until after they picked up the mustang from the park...but then they worried that he was suicidal yet waited til Friday to invite LE to speak with them. JMO
