One relatively minor point is the 911 call was connected at 7:09:34 pm. The shot that killed TM can be heard 41 seconds into another 911 call that began at 7:16 pm for a time of 7:16:41 when Trayvon was shot.
That's a difference of 7 minutes and 7 seconds, not 8 minutes. Another factor to consider is that for the first 2:07 of the call, TM is walking in full view of Mr. Zimmerman. He started running at 2:07 into the call per GZ for a clock time of 7:11:41, exactly 5 minutes before he was shot and killed.
Okay, use whatever time frame you are most comfortable with, how long would it take to walk from one end of the complex to the other? Is 15 minutes to walk a mile reasonable? If Trayvon felt he was in danger, is it your opinion he could not make it home in five minutes from any point in the area of the complex in question?
Your point being that why didn't he make it home has certain possibilities to consider, such as, what if someone was waiting in ambush down this long sidewalk?
What if TM lost sight of his pursuer and started walking?
What if that someone had lived there longer than a few days, and knew enough to know he could run the path in red, himself?
Again, choose any point and timeframe you'd like, if the kid was scared, he should have been able to make it home with ease.
I'm not saying that's what happened, mind you, but what if it did? A forced march back to a vehicle would start explaining how the body could be found where this dispatcher says, wouldn't it?
Sure, but what evidence do you have that there was a forced march?

Other than that, I can't think of too many reasons, myself, that TM didn't make it home with his Skittles and tea.
