No. My assumption is that Zimmerman likely didn't wander far from the general area that he was believed to be at the end of the phone call in order to place him at the scene of the altercation.You are going on the assumption that Zimmerman stayed put when he got off the phone.
Martin was known to have left this general area, Zimmerman was not. It certainly does not make sense for them to have both left this area and returned to have the altercation. (simplest theories tending to be more correct and all.)
As I understand it, the 'chase' witness has recanted. She is aparently only sure that she saw one person running. That could have been Martin running down the N-S sidewalk as reported in Zimmerman's call.There is a witness who claims to have seen some type of chase or someone running down the path.
There are no houses. These are apartments or condos. Five doors down from the final location still places the initial altercation next to the first building and toward the north end of the sidewalk.There's also a witness or maybe its the two roommates, who say the altercation started further down the path (at least five houses further).
