Here's the problem with your theory that Martin wasn't in the area by the condo, 25. Trayvon Martin takes off running from George Zimmerman cutting off the call to his girlfriend. When she calls back a minute plus later he's breathing hard from that running. So tell me how it is that a young man in good physical condition can run for anywhere even close to that amount of time and NOT have covered the two hundred yards to the condo? The fact is...in the amount of time from when Zimmerman announces to the 9/11 operator that Martin is running until the time that the girl friend calls him back he could EASILY have gotten to the condo. As a matter of fact it's hard to conceive of him NOT making it that far. If he only runs half way (as in your diagram) then why would he be winded when the gf calls back over a minute later? Sorry but that's a hard scenario to envision. I don't think the gf realized what she was saying when she repeated several times that Martin was by the condo. That statement by her...coupled with Martin's "Cracker" comment but Martin several hundred yards away from Zimmerman and paints him as someone who isn't scared but annoyed at being followed. It isn't logical for someone who is frightened to go towards the thing that is supposedly frightening them and away from safety. It IS logical for someone who is angry to go towards the thing that is causing that anger. That's what I think happened that night. I think Trayvon Martin decided that he wasn't going to run from the "Cracker" that had questioned him...he was going to go back and confront him. That's the only scenario that makes sense.
I have no idea...he is running up the walk and then down the sidewalk and in between the two buildings in the rain...while on the phone...yeah he could be breathing heavy for sure. Hell, look at the breathing sound that is coming from GZs phone as he immediately starts running...that was how the dispatch thought he was following.
So yeah, he most definitely could have been breathing hard for sure. It was dark, it was raining, it was abnormally cool that night, hes on the phone...hell yeah it would have sounded like the kid was out of breath.
Look at the distance down the sidewalk...we are talking about a stretch of less than two minutes according to GZ and the 911 call...GZ also does not describe Trayvon as actually running he describes him as walking briskly in his interview with sean hannity...GZ specifically says he was not running, but that he meant he was walking faster and getting away.
The the distance between the T in the sidewalk and the fiances house is more than 120 yards (more than a football field)...so no I dont believe in a span of less than two minutes he went that entire distance and back. Thats why I dont think it makes sense with the timeline and GZs own account of the events. He cut up the pathway and went right...when GZ came up the path, he looked and saw no one...suggesting that by now, Tray had cut between the buildings.
