1) TM passed by GZ in his truck. From the 911 call it is clear TM does this. Looking at an aerial view of the neighborhood it seems to me TM would have had other choices yet he chooses to pass by GZ's truck.
According to George the -only- place Martin 'passes by' his truck is when George is parked at the Clubhouse. Please show me how Martin gets to Twin Trees Lane without going past the Clubhouse on Retreat View Circle, or please show that it was possible (and Martin knew it was possible) to cut the long way around behind the Clubhouse.
2) TM had plenty of time and opportunity to make it home but he chose not to go. Serino seems to be under the impression TM was hiding somewhere but TM knew he has lost GZ because Dee confirms he did. Again, looking at photos it is easy to see how wide open the area is.
And George had plenty of time to get back to his truck. How is either point relevant. And how is TM supposed to 'know' he had 'lost' George? Did George 'know' he had lost Martin? No he did not - and we know that because even after he had lost sight of Martin, George did not want to say his address out loud.
3) TM confronts GZ. Whether TM asked GZ why he was following him or TM asked of GZ had a problem TM is the first to speak. The area where the struggle started looks open so it seems TM had to have approached GZ. That is not the actions of someone who is afraid.
Sheesh. Project much? If Martin was scared he wouldn't say something first? If he was scared he's just stay quiet and let George approach him? How does that even make any sense? If the area was so open why wasn't George able to just mosey on back to his truck? Remember: the *only* evidence we have of either guy following the other is George following Martin, not the other way around.
Also, DeeDee says Martin asks 'why are you following me' - that seems like an extremely reasonable, logical, and likely thing to ask to the guy that's been tracking you in his car and on foot for the last quarter of a mile
Her testimony just doesn't ring true to me.
There are lots of reasons her testimony might not ring true, but your points above aren't any of 'em.
