From ABC News:
A police surveillance video taken the night that Trayvon Martin was shot dead shows no blood or bruises on George Zimmerman, the neighborhood watch captain who says he shot Martin after he was punched in the nose, knocked down and had his head slammed into the ground.
The surveillance video, which was obtained exclusively by ABC News, shows Zimmerman arriving in a police cruiser. As he exits the car, his hands are cuffed behind his back. Zimmerman is frisked and then led down a series of hallways, still cuffed.
Zimmerman, 28, is wearing a red and black fleece and his face and head are cleanly shaven. He appears well built, hardly the portly young man depicted in a 2005 mug shot that until a two days ago was the single image the media had of Zimmerman.
