The witness named Good said Trayvon was on top of Zimmerman using MMA moves --- martial arts moves. Yet Zimmerman was the guy who took MMA classes twice each week at the local gym.

Zimmerman said he was pinned underneath Martin on the concrete walkway where he somehow got a vertical laceration on his head, huh? They look like slashes. Banging his head up and down on concrete and he has a linear cuts as if you bang your head on a car door or the zipper on his leather coat? Maybe the cuts are from Trayvon hitting him with his cellphone? Did the medical examiner say what caused the cuts? There was no blood on the concrete.

Yet Martin is found dead on the grass not the walkway. No indication he got up and walked away after being shot.

There was constant hysterical screaming for help on the 911 call, and the screaming ended with the gunshot. Seems that the person screaming stopped because he was dead.
