No, I sure wouldn't-and haven't on the numerous occasions my drive has been used as a turnaround.
From a guilty perspective, a person might call the police as an afterthought, to create a getaway vehicle where there was none, to deflect attention away from themselves.
IF there was a car, it had to have been parked in the drive longer than to just turn around. So how did DR hear/see a car turn around, yet miss a car pulling in and not hear car doors from a car which would have been closer to the house? Jacob's footprints showed resistance, so it seems likely the car door would have been shut hard once he was in the car.
And while on the subject, I have always wondered why a perp would hide their car in some random driveway, not knowing if the habits of the homeowners? They could pull in/leave at any moment, or even come walking down the drive to bring the garbage to the road, or outgoing mail to the mailbox? There would be no hiding then, and how do you explain blocking someone's drive?
Why not just park on the road, where, if seen, you could just say you were lost? Easier yet, why not just follow the boys (not knowing where they were heading) then pull up beside them, order one to get in and tell the others to run?
I also can't figure why a perp, who was ready enough to have a gun and a mask handy, would wait til after 9pm-an hour he would be unlikely to find kids out alone-to make his move? He would have already had about 3 hours of darkness for cover. On an unusually warm Oct evening in the late 80's, I am sure there were a plethora of kids outdoors earlier that evening.
For all these and a multitude of other reasons already discussed in the threads once the car theory was debunked, all the puzzle pieces kind of fell right in to place for me. jmo
