Zimmerman, 28, is being held on charges of second-degree murder for the Feb. 26 shooting of Martin, 17, which could carry a life sentence if he is convicted.
The exclusive image 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.
