With a single punch, Trayvon Martin decked the Neighborhood Watch volunteer who eventually shot and killed the unarmed 17-year-old, then Trayvon climbed on top of George Zimmerman and slammed his head into the sidewalk, leaving him bloody and battered, law-enforcement authorities told the Orlando Sentinel.
That is the account Zimmerman gave police, and much of it has been corroborated by witnesses, authorities say. There have been no reports that a witness saw the initial punch Zimmerman told police about.
Zimmerman has not spoken publicly about what happened Feb. 26. But that night, and in later meetings, he described and re-enacted for police what he says took place.
In his version of events, Zimmerman had turned around and was walking back to his SUV when Trayvon approached him from behind, the two exchanged words and then Trayvon punched him in the nose, sending him to the ground, and began beating him.
