Defense attorney Mark O’Mara on Thursday posted statements — eight on audio, two on video and one written — in which Zimmerman gave police his version of the night’s events. The tapes show he was calm, sometimes dazed, and neither upset nor remorseful. He was consistent in his account that a “suspect emerged from the darkness” and punched him so hard in the nose that he fell.

Just a day after the shooting, Zimmerman cooperated with police and returned to the gated community as they shot video of him re-enacting the fight. He described where he first saw Trayvon, how he followed after him and how Trayvon set upon him and tried to seize his gun.

Trayvon, he said, “wailed” on his head so hard it felt like he was being hit with bricks. Zimmerman said he grabbed the gun first and “fired one shot,” causing Trayvon to kind of sit back and say: “You got me. You got it.”

Simmerman indicated that he didn’t realize Trayvon was shot at this point, though it was point-blank range.

“I didn’t think I hit him,” Zimmerman told police during the re-enactment. “I thought he was just saying: ‘I know you have a gun now. I heard it. I give up.’”

That night Zimmerman gave a detailed verbal statement to a police official who used voice-analyzing software to help determine the veracity of his statements.

The videos mark the first time the public can see and hear how Zimmerman described the lead-up to his confrontation with Trayvon and what led him to shoot the Miami Gardens teen on that rainy evening at a gated community in Sanford. They show him on the day after the killing wearing two mid-sized butterfly bandages on the back of his hand and a bandage between his eyes.

Two days later, a police video showed he wore a much larger bandage.

On the tapes released Thursday, Zimmerman said Trayvon “appeared out of nowhere.”

“You got a problem?” Zimmerman said Trayvon asked. In another statement, he phrased it, “You got a f---ing problem, homie?”

“I said no, I don’t have a problem,’” Zimmerman said he responded. He said he fumbled for his cellphone and thought it was in his pants. But it was in his jacket pocket.

“He just punched me in the nose. And I fell backwards and to the side, and somehow I wound up on my back. He ended up on top of me. And he just kept punching my face. And my head. And I was screaming for help,” Zimmerman said.

“Shut the f--- up,” Trayvon said as he kept punching him, Zimmerman recounted.

“He slammed my head into the concrete,” Zimmerman said. “Each time it felt like my head was going to explode… And then he covered my nose with one hand and my mouth with the other one. And he told me shut the f--- up. And I couldn’t breathe. I was suffocating. And all I could think about was I didn’t want him to keep slamming my head against the concrete.”

Serino played a 911 tape for Zimmerman that recorded the scuffle, and questioned how he could be screaming for help so loud with a hand over his mouth. In many instances during the interview, Serino talks but either hardly gives Zimmerman a chance to respond or Zimmerman’s answers are not audible.

Another investigator present as Serino played the police emergency tapes accused Zimmerman of misleading her the night of the killing, when he claimed that he got out of his car only to check for an address.
