Zimmerman first agreed to meet the police by his vehicle, near the mailboxes on Twin Trees. But then he said they should call him so he could tell them where he was. It sure doesn't seem like he intended to return to his vehicle immediately.
For some reason or another he decided to go on the pathway which runs behind the houses ... in the opposite direction from where he was parked. And on that pathway the shooting took place.
