Another post at CTH a year ago documented very clearly that TM either waited in the bushes or more likely doubled back from the house to jump GZ. If the defense needs to put on a case, I’m sure we’ll see it posted here at some point.
My speculation:
Martin was checking out some apartments, to see what he could steal (stolen jewelry didn’t just magiaclly appear in his bag at school...he gets it from somewhere). He got spooked by Zimmerman, and ran.
The the lovely Ms. DeeDee criticized him for not taking care of the crazy ass cracker.
Well, the budding street fighter and drug dealer, Travon, couldn’t hurt his rep like that.
So he went back and ‘started something’ with Zimmerman.
