This should not be complex, or mysterious and the final investigation regarding the event should be rather quick.
All the players are accounted for, and there were said to be witnesses, there is audio, cells involved w/records etc.
Stop attempting to make this wordy or somehow complex.
It’s become wordy here, hasn’t it? As far as witnesses, are there any eyewitnesses? I thought not. It’s nothing but the 911 call recordings, Zimmerman’s self-interested testimony, and the police report after the fact, as far as I can tell. So OK, it’s more like a Columbo mystery with Peter Falk returning repeatedly (to Zimmerman) and saying, “Excuse me, there is this one more thing.”
