What a sad, though expected, ending :-(
My anti-theories:
- Driving all the way there to go cruising —> unlikely because of his upcoming call that morning. A quicky is one thing, but driving ca. 30 miles in total if you have a meeting to catch, no.
- Meeting someone in the College Park —> unlikely because he would've taken the car keys with him. I also doubt he would've parked the car uphill in that weird little spot (marked red in my pic below)
- Car-hijacking during the very short drive from the gas station to home, at a time when the first commuters are well on their way —> possible, but unlikely. Also no signs of struggle in the car, as far as we know.
My only theory is that he went there to take his own life. But, that immediately gets contradicted by the hidden car. Sorry, I'm not being too helpful here, just ruling out three scenarios IMHO.
As for the spot where he was found: I believe that to be north of where the Porsche was located. I am not sure if that wooded area is still part of the College Park, but Google Maps shows that the College Park, with its tennis court, butts up against the road (Bonnie View Road), so it's possible the survey crew regularly checks the woods just across the road?
