The battle continues over what injuries killer George Zimmerman may or may not have suffered in a confrontation with 17-year-old Trayvon Martin. New information reveals that an ambulance ready to be dispatched to treat Zimmerman the night of the killing was canceled, raising doubts that Zimmerman was badly beaten by Martin, as he has said. The latest information follows the appearance of possible wounds on Zimmerman's head in enhanced scenes of a video taken at a police station the night of the killing. ABC had reported earlier that there were no signs of injury. A new expert, however, is saying there is no indication that Zimmerman's nose was broken, even though he said Trayvon punched him in the face—and slammed his head into concrete.
Any injuries were apparently not severe enough for a paramedic to check out, notes CBS. One ambulance on the scene was dealing with Martin. In recordings of conversation between police and an ambulance dispatcher, one person is heard asking: "Do they have a second patient?" Another answers: "That's affirmative, there's a second patient." But a rescue worker responds: "You can cancel the second rescue." Zimmerman's injuries could be critical to his defense that he killed Trayvon because he thought his life was in danger. Trayvon's family said injuries suffered in such a confrontation would require medical help. (Read more George Zimmerman stories.)
