One lost guy. Another who actually parked near his own home before continuing his search on foot taking shortcuts from his home to the sidewalk. You can see the trails on Google.
If all Zimmerman had done was follow Martin, he couldn't have lost him ~ he knew his way like the back of his hand. If, instead he cut through home to get his gun to continue the search armed, he'd got there first.
HE Didn't have to cut back on his path to go home. Just turn left at the sidewalk to the North and he'd been there.
So now Martin was “lost?” Now Zimmerman has been “intensely patrolling” the neighborhood since years before it was even built?
You have put together quite an imaginative scenario, but again, I have trouble squaring it with the known facts.
I’m sure you can easily construct another fanciful scenario (added difficulty: it must all take place in a timespan of about two minutes,) but for what it’s worth, you are mistaken about the location of Zimmerman’s house.
That said, the map below doesn't quite square with GZ returning directly to his vehicle to wait for police. "F" is the spot where TM was shot.
