"DiMaio testified that lacerations to the back of Zimmerman's head were consistent with it striking a concrete sidewalk, as the defendant has claimed. Later, when looking at photos of Zimmerman's injuries taken the night of the shooting, DiMaio identified six separate impacts to Zimmerman's face and head. He said he believed Zimmerman's nose had been broken.
"It's obvious he's been punched in the nose and hit in the head," he said."

And I said he was hit at least 4-7 times.
Maybe I should be a pathologist!! ;-)
