But that brings up another question I hadn't considered until now. GZ says he was following TM on foot and lost sight of him. Why? Where did TM go? Did he go around a corner or into a doorway and GZ just didn't see him? Possible.

Or did TM duck behind something and hide waiting for GZ to get closer? Could he have been waiting to jump GZ?

There's just too much we don't know, and may never know, even if there is a trial.
