According to the Miami Herald, Zimmerman told the police that he had stepped out of his SUV to check the name of the street he was on, and that Trayvon sprang out of nowhere to attack him from behind as he was walking back to his truck. He said he feared for his life and shot Martin in self-defense. That account doesn't easily fit into the narrative cobbled together from what evidence had been made public.
Zimmerman's call to 911:
"This guy looks like he's up to no good, or he's on drugs or something," Zimmerman tells the 911 operator. "He's just staring, looking at all the houses. Now he's coming toward me. He's got his hand in his waistband. Something's wrong with him."
Zimmerman described Martin as wearing a hoodie and sweatpants or jeans.
Zimmerman continues: "He's coming to check me out. He's got something in his hands. I don't know what his deal is. Can we get an officer over here?"
"These assholes always get away," he says later to the operator. Zimmerman is then heard giving directions to the dispatcher.
"Shit, he's running," Zimmerman says.
"Are you following him?" the dispatcher asks.
"Yes," Zimmerman responds.
"We don't need you to do that," the dispatcher says.
Zimmerman continued to pursue Martin, and moments later other calls started coming in to 911. Neighbors reported hearing screams, cries for help and then gunfire. Some sobbed as they talked about a dead boy and a man standing over him. In one recording, the sounds of wailing and what seem to be pleas for help and "No! No!" can be heard.
What actually happened:
Just moments before Trayvon Martin was shot and killed, he was on his cellphone talking with a 16-year-old girl. For the first time, the girl is speaking out about the last, horrifying moments of Martin's life.
"He said this man was watching him, so he put his hoodie on. He said he lost the man," the girl told ABC News. "I asked Trayvon to run, and he said he was going to walk fast. I told him to run but he said he was not going to run."
According to accounts gleaned from 911 audio recordings made the night of the killing and the teenage girl's statements, Martin eventually did run. But Zimmerman wasn't far behind, and soon the two would be face to face. Zimmerman, the self-appointed captain of the neighborhood watch, was armed with a 9mm pistol. Trayvon had little more than a bag of candy in his pocket.
"Trayvon said, 'What are you following me for?' and the man said, 'What are you doing here?' Next thing I hear is somebody pushing, and somebody pushed Trayvon because the headset just fell. I called him again and he didn't answer the phone."
The line went dead, according to the girl's account.
