The photo below is a screen capture from a video shown on CBS Evening News on April 23, 2012. The video is of a story titled "What's Next For Zimmerman, Sanford FL" and the section with the police video of the crime scene runs from about 1:59 to 2:04 in the clip. The photo below was captured at about 2:02 in the video.
The reporter does not comment on this particular video segment but presumably it is footage recorded by Sanford PD on the night of the shooting. The police officers appear to be standing on the sidewalk that runs between the backs of two rows of townhouses in the Reteat at Twin Lakes gated community. A body is lying beneath a yellow tarp about 7 to 10 feet off the sidewalk.
This photo seems to contradict at least part of the story told by George Zimmerman. The position of the body belies his reported account that Trayvon was pounding Zimmerman's head on the concrete sidewalk, as the body is lying entirely upon grass several feet away from the concrete.
