I dont know what happened... but if i had to GUESS...
I'd say trayvon got away then slowed down once he got around the corner. Zimmerman went thru behind the bushes (as an angry ninja neighborhood watch commander who had just lose sight of the kid aroundthe corner would do).
They ran right smack dab into each other. Trayvon on phone with GF, having just run two blocks.
ZImmerman - who had the balls to push a fcking cop a few years back - and maybe a few beers in on a sunday afternoon and history of alcohol counseling - probably charged at the kid using some profane language with his hand onthe butt of pistol, front waist band. Pissed off cowboy, knowing the cops were 60 seconds away, wanting to interrogate trayvon before they arrived so he could be 'THE MAN" and so trayvon would admit where zimm's stolen bike was. it was a nice bike!
Trayvon is scared and mad and embarassed and tired and they go right into a scuffle. Trayvon clocks him in the nose and they grapple. zimmerman, who had attended a MMA/karate gym for 1.5 years, and is 30+ pounds heavier, does get on top of the 6 foot something, 155 pound twink. Yes, he got on top. He drew his gun and pressed it against trayvon, probably hopeing trayvon would just stop moving and submit, as he had lost control of situation and even though he hated this punk, he sure as shit didn't want to shoot him. Trayvon (i think it was him screaming, as does the expert, but I know defense disagrees) - trayvon starts to get up and zimm just shoots him accidentally.
ANd trayvon was dead. zimm wasn't trying to help him - he got off and was pacing with gun mumling - he was not tested for alcohol, but i think any 27 year old with a history of state-ordered alcohol counseling, who once shoved a cop while drunk, with domestic abuse charges.... well, if he's wrasslin in the night with some punk kid he jsut chased down, it's probably not sober. Again, completely my own GUESS of how it went down. They never checked, but i bet his trip to Target that night (ironically) involved the purchase of a 12 pack.
THis isn't a thread on "you're a liar, you can't prove XYZ"... answers may come to light as the trial progresses. But what is you personal belief or what probably happened that night, IN YOUR BEST GUESS?
