In his police report, Tim Smith wrote that when he got to the scene, he saw that Zimmerman's back was wet and had grass clippings on it. That suggests the defendant had been on the ground, facing up.
Tim Smith also wrote that he saw blood coming from Zimmerman's nose and the back of his head.
Zimmerman, he wrote, complied with his requests, put his hands in the air, allowed the officer to snap on handcuffs and to pull Zimmerman's handgun from his waist.
Zimmerman admitted shooting Trayvon, Smith wrote.
Sanford firefighters cleaned up Zimmerman as he sat in the back of Tim Smith's patrol car, the officer wrote, and while that was happening, Smith heard him say, " 'I was yelling for someone to help me, but no one would help me.' "
