But again, the points hinge on how close TM was to GZ when he took off. If he came close enough to check GZ out, that implies that he was closer to the junction of the road where GZ was parked and the beginning of the cut through. If he took off from that point, it seems that turning between the building would better fit the time and GZ's observation of his direction. Taking the first available turn (the sidewalk between the buildings) and breaking line of sight would also make more sense than running in a direction that would give GZ a sustained line of sight. The E point on the blogger's map/timeline just doesn't make sense to me.
Since we're assuming. Assume GZ is in his car and TM is "checking him out" from about the corner. GZ starts unhooking his seatbelt, looking like he's getting out, and TM takes off down the street. GZ exits, fast walk/run to the corner and sees TM disappear between the buildings down to the left. GZ follows, takes the same cut-through. Police ask where he lives and GZ starts to say then whispers he (paraphrasing) "needs to be careful because he doesn't know where TM is". He walks North, then towards the "E" to get his bearings. His father referred this "E" spot in an interview. And the Police recording might reference this spot as well.
Probably be best to listen to the call while looking at the map.
Thing is, if GZ took that route, cut through between the "G" bldg and the one just south of it, TM would have had a great opportunity to watch him. Might have followed him until he got off the phone.
