Based on the call, there it was about 3-4 seconds between GZ's "ah, shit - he's running!" and the time the door opened. It was another 18 seconds or so before he acknowledged the dispatcher's "we don't need you to do that." How much of a head start did TM have? If TM only had a few yards and a few seconds on GZ, would TM's instinct been to have run down a straightaway that was completely exposed if he thought GZ might not have been too far behind? Could GZ have been able to reach the north end of the walkway in time to see TM if TM was running down the straightaway for home? Were there lamps or security lights between the building, any porch lights on, any ambient light from any of the homes? Could GZ hear running footsteps?
That GZ didn't mention any of the above is something that makes me think that TM ran and ducked.
