George Zimmerman: I thought I missed when I shot Trayvon Martin He just kept slamming and slamming. I kept yelling help as loud as he could. He put his hand on my nose and his other hand on my mouth and said "shut the ---- up" and I tried squirming again. When he was hitting my head it felt like my head was going to explode. I thought I was going to lose consciousness," he said. Zimmerman appears in the footage with bandages on the back of his head and his nose, offering some corroboration to his claim that Martin attacked him. According to the 28-year-old, who is currently in a Florida prison awaiting trial on a charge of second-degree murder, Martin saw his pistol and tried to grab for it. Zimmerman said he fended Martin off and was able to reach the gun himself. I just grabbed my firearm and I shot him one time. After I shot him he sat up. I didn't think I hit him because he sat up and he said 'Oh, you got me. You got it. I thought he was just saying: 'I know you have a gun now, I heard it, I'm giving up'. I don't know if I pushed him off me or he fell off me either way I got on top of him. The 15-minute clip ends with Zimmerman describing how he put up his hands as police officers reached him. The footage was part of a tranche of evidence released by Zimmerman's lawyers following a failed legal attempt to keep it out of the public domain. The released documents include a handwritten "narrative report" where Zimmerman claims that Martin shouted "You're gonna die tonight, mother ------" as he reached for the gun. Across four pages of dense handwriting, Zimmerman reveals his familiarity with police jargon from his time in the neighbourhood watch, describing Martin as "the suspect" and explaining how he "unholstered" his weapon.
