The network has a surveillance video of Zimmerman arriving at police headquarters shortly after the incident that appears to contradict his—and the police report's—version events that led to Martin's death. Zimmerman says he was punched in the nose, knocked over, and that his head was slammed into the ground by Martin. But in the video, Zimmerman has no visible blood or bruises.
The Sanford police report has backed up parts of Zimmerman's version of events, noting blood on the back of his head and nose after the confrontation, and adding that he received medical attention at the scene before being taken to the station.*
