Correct me if I'm wrong. I'm not as up on the physical locations as some of the other evidence. Frank Taafe's address is 1460 RVC. I believe his house was the one Z speaks of as having been broken into and being unsecured (doors and windows unlocked and garage door open) during the previous incident. That is the same house that Z saw TM looking into. If I've got all those details right, then it makes sense that TM came through that shortcut and was beside Taafe's house when Z first spotted him and found him suspicious.
Z then drives around to somewhere near the clubhouse and calls the NEN. At that point he sees TM "behind him", so TM must have come through the shortcut by Taafe's house and then walked around RVC and passed Z near the clubhouse.
That is the way I see it, too. I can't figure out the rain and the mail shed though if you want to give Dee Dee any credit.
After TM passes the truck while it is parked (however) in front of the clubhouse, GZ gets sight of TM again on Twin Trees long enough to see him disappear down the E-W sidewalk and behind the THs. I am thinking the second sighting is when TM did his posturing, hands in pants thing. The question I have is did GZ get ahead of TM again while in his truck or did TM actually reappear to do it.
Do you remember if GZ brought up the "circling" first or did Singleton?
ETA: The actual word "circling" instead of passed by, for example.
Sorry, I had a very long day and am too tired to go through the transcripts. I need a nap!
