Martin funeral director: No signs of fight on body - CBS News Would the victim have some injury from beating the Zimmerman senseless? There are more photos of Zimmerman in this story; no sign of injury still. CBS News) SANFORD, Florida - The defense of George Zimmerman rests on a violent fight that he said occurred before he fired the shot that killed Trayvon Martin. Zimmerman is neighborhood watch volunteer at the center of the case. It was almost five weeks that Martin, the unarmed 17-year-old, was killed after Zimmerman found him suspicious. We don't know what happened immediately immediately before the shot was fired. CBS News correspondent Mark Strassman has new evidence in the case. Trayvon Martin was buried in Miami with a gunshot wound to his chest. But otherwise, according to Richard Kurtz, the funeral director who prepared Martin for burial, his body showed no injuries. "We could see no physical signs like there had been a scuffle [or] there had been a fight," he said. "The hands -- I didn't see any knuckles, bruises or what have you. And that is something we would have covered up if it would have been there."
