Hi, new to this forum - been cracking my mind on this case for a couple of days.
One thing that really stands out to me, is the sophistication behind it all: To move a car to a remote area, and to get away from that (creepy) part of town asap, it would have to be a two-man operation. One drives the Porsche, another one trails behind, together they leave.
Whoever is in on this / behind it, and I am leaving all options open, didn't do this on a whim. Whether Alan is alive remains to be seen, but moving the car has been a premeditated course of action - and I find it unlikely that your average tweaker or low-life robber would spontaneously think this out (and find an accomplice) at 6:00 in the morning.
