The funeral director who oversaw slain teenager Trayvon Martin's burial says the body bore no signs of a fight.

Richard Kurtz says there were no notable marks on Martin's hands, face or body other than the gunshot wound that killed him. Kurtz says he expected to see some marks if Martin had been in a fight.

The 17-year-old Martin was killed Feb. 26 by neighborhood watch volunteer George

Zimmerman in the city of Sanford, where Martin was visiting. Zimmerman claims Martin physically attacked him after Zimmerman questioned why he was in the neighborhood.

Kurtz says the condition of Martin's body raises questions about Zimmerman's self-defense claim. Zimmerman has not been charged, leading to racially-tinged protests around the country. Martin was black; Zimmerman's father is white and is mother Hispanic.
