Zimmerman photo clearly shows head injuries: Evidence mounts that he was, indeed, defending himself against Trayvon's attack

"The exclusive photo obtained by ABC News shows blood trickling down the back of Zimmerman's head from two cuts. It also shows a possible contusion forming on the crown of his head. The original police report that night notes that the back of Zimmerman's head was wet, and that he was bleeding from the nose and head.

Zimmerman told police that night that he shot and killed the teenager in self-defense after Martin punched him and pounced on him. Zimmerman told police that Martin then bashed his head into the concrete sidewalk during the altercation that took place in the tidy middle-class development of the Retreat at Twin Lakes in Sanford, Fla."
