"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."
