Having reviewed the first wave of discovery Jeralyn Merritt lays out her best guess as to what happened on the night of Feb 26.
Do keep in mind it is a mix of "facts" (i.e., witness statements and physical evidence) and highly informed speculation.
Let me highlight this:
GZ did not have TM in sight when the dispatcher told him they didn't need him to follow TM. He responded OK. He didn't follow him after that. He didn't know where Trayvon was. He continued walking towards the front of the Retreat View Circle, where the first house is 2861, home to W-13 and W-12. He then turned around to walk back to his car. He just passed the T and the pet waste can when Travyon came up on his left.
That is Zimmerman's story, as told by his father - crossed the top of the sidewalks 'T' from Twin Trees Lane to Retreat View Circle and then headed back.
However, several minutes elapsed between the end of Zimmerman's 911 call and the fatal encounter. Zimmerman had plenty of time to wander down and around the commons area, which was my guess at the end of March.
Legally, one might say, so what? It was dark, no witnesses saw him, and Zimmerman is legally free to walk around his neighborhood. However, it speaks to his credibility, and it seems to me that crossing the 'T' to Retreat View Circle and then heading back should not have taken as long as it seems to have taken.
Well. This may have inspired doubts in the minds of the police and we hope it helped motivate their investigation, but there comes a time when the state needs to move past a theory of the crime and start offering proof of a crime. I think the state is stuck at a theory.
