Supposedly, Martin was on the phone with his girlfriend up to the point where the confrontation occurred. She reportedly said words were exchanged with somebody just before the call dropped, at 1912. The police arrived on scene at 1917, by which time the incident was over, and Martin was already dead.
There's a problem with 1912, however. Zimmerman was still on the phone with the police. His call didn't end until about 191340, and the fight started sometime after that.
So, something is not right. Either the girlfriend is lying, the 1912 time is misreported, or either the cell company's clock or the police's clock was wrong. Cell companies are quite persnickety about keeping their computer clocks accurate to the millisecond. I would hope the Sanford PD keeps theirs accurate to at least the second.
I'd like to see it all laid out for posterity. But, given what we know now, I can't see how a fair jury could convict Zimmerman of anything.
We’ll have to see her cellphone records to verify.
