SANFORD, Fla. -- "He took my head and slammed it against the concrete several times, and each time I thought my head was going to explode and I thought I was going to lose consciousness," George Zimmerman told police the day after he shot and killed Trayvon Martin.
"I started screaming for help," but Martin pressed his hands over Zimmerman's mouth and nose, he said. "He told me to shut the f&#k up, and I was suffocating."
Zimmerman told police he was lying on the ground, but his head was on the concrete.
"I didn't want him to keep slamming my head on the concrete so I kind of shifted. But when I shifted my jacket came up...and it exposed my firearm. That's when he said you are going to die tonight. He took one hand off my mouth, and slid it down my chest. I took my gun aimed it at him and fired."
The latest and most detailed account yet of what happened in Sanford, Fla., on Feb. 26 comes from a voice stress test that Zimmerman passed, along with a video re-enactment, a handwritten statement and audio interviews conducted in the days after the shooting by investigators.
The material was released by Zimmerman's attorney today on the website gzlegalcase.com, a website managed by the Zimmerman defense team.
The relatively consistent statements portray a man trying to convince investigators that he was in a life and death struggle that left him with little choice but to kill the unarmed teenager.
The documents also show that in the days following the shooting, the lead investigator was not accepting Zimmerman's version of events and recommended that charges be filed against Zimmerman.
"I shot him, and I didn't think I hit him because he sat up and said, 'Oh you got me. You got me, you got it,'" said Zimmerman during a nearly 20-minute re-enactment shot by investigators at the scene of the shooting the next day.
In the video Zimmerman, 28, gives a blow by blow description of how the fight began and depicts Martin as the aggressor, a key point as his legal team builds his defense on Florida's controversial "stand your ground" law.
Zimmerman said he was driving to buy groceries when he spotted the unarmed teen walking near a house that he knew Martin did not live in and called police to report a suspicious person.
"I just felt like something was off about him...and there's been a history of break-ins ... so I said you know just better to call. I kept driving and I passed him, and he kept staring at me and staring around," Zimmerman said.
He took investigators to the house where he first spotted the teen and got on the phone with police. At that point he says he lost sight of Martin.
With bandages clearly visible on the back of his head and nose in the video, he took investigators through the neighborhood showing them where he was when the responder told him that he did not have to follow Martin. Zimmerman says by the time of the request he was no longer in his car and wanted to figure out exactly where he was in the subdivision, so that the officer dispatched to the scene could find him.
"I was walking back. I didn't see anything again, came back to my truck and when I got to right about here, he yelled from behind to me."
"He said, 'Yo, you got a problem?' and I turned around and said no I don't have a problem," said Zimmerman.
