After weeks in hiding, George Zimmerman made his first courtroom appearance Thursday in the fatal shooting of 17-year-old Trayvon Martin, and prosecutors outlined their murder case in court papers, saying the neighborhood watch volunteer followed and confronted the black teenager after a police dispatcher told him to back off.
The brief outline, contained in an affidavit filed in support of the second-degree murder charges, appeared to contradict Zimmerman's contention that Martin attacked him after he had turned away and was returning to his vehicle.
In the affidavit, prosecutors also said that Martin's mother identified cries for help heard in the background of a 911 call as her son's. There had been some question as to whether Martin or Zimmerman was the one crying out.
The account of the shooting was released as Zimmerman, 28, appeared at a four-minute hearing in a jailhouse courtroom, setting in motion what could be a long, drawn-out process, or an abrupt and disappointingly short one for the Martin family because of the strong legal protections contained in Florida's "stand your ground" law on self-defense.
During the hearing, Zimmerman stood up straight, held his head high and wore a gray jail jumpsuit. He spoke only to answer "Yes, sir" twice after he was asked basic questions from the judge, who was not in the courtroom but on closed-circuit television. The defendant's hair was shaved down to stubble, and he had a thin goatee. His hands were shackled in front of him.
He did not enter a plea; that will happen at his arraignment, which was set for May 29.
To prove second-degree murder, prosecutors must show that Zimmerman committed an "imminently dangerous" act that showed a "depraved" lack of regard for human life. The charge carries a mandatory sentence of 25 years in prison and a maximum of life.
The special prosecutor in the case, Angela B. Corey, has refused to explain exactly how she arrived at the charges. But in the affidavit, prosecutors said Zimmerman noticed Martin while patrolling his gated community, got out of his vehicle and followed the young man.
Prosecutors interviewed a friend of Martin's who was talking to him over the phone moments before the shooting. His parents' lawyer has said that Martin was talking to his girlfriend back in Miami.
"During this time, Martin was on the phone with a friend and described to her what was happening," the affidavit said. "The witness advised that Martin was scared because he was being followed through the complex by an unknown male and didn't know why."
During a recorded call to a police dispatcher, Zimmerman "made reference to people he felt had committed and gotten away with break-ins in his neighborhood. Later while talking about Martin, Zimmerman stated 'these a------s, they always get away' and also said 'these f punks,' " the affidavit said.
It continued: "When the police dispatcher realized Zimmerman was pursuing Martin, he instructed Zimmerman not to do that and that the responding officer would meet him. Zimmerman disregarded the police dispatcher and continued to follow Martin who was trying to return to his home."
"Zimmerman confronted Martin and a struggle ensued," prosecutors said in their account.
The account provided no details on the struggle.
Zimmerman told authorities that Martin attacked him as he was going back to his vehicle, punched him in the face, knocked him down and began slamming his head against the sidewalk.
For all the relief among civil rights advocates over the arrest, legal experts warned that there is a real chance it could get thrown out before it ever goes to trial because of Florida's "stand your ground" law, which gives people a broad right to use deadly force without having to retreat from a fight.
At a pretrial hearing, Zimmerman's lawyers would only have to prove by a preponderance of evidence -- a relatively low legal standard -- that he acted in self-defense in order to get a judge to toss out the second-murder charges. And if that fails and the case does go to trial, the defense can raise the argument all over again.
There's a "high likelihood it could be dismissed by the judge even before the jury gets to hear the case," Florida defense attorney Richard Hornsby said. Karin Moore, an assistant professor of law at Florida A&M University, said the law "puts a tremendous burden on the state to prove that it wasn't self-defense."
Zimmerman's attorney, Mark O'Mara, said his client will plead not guilty. At some point soon, the lawyer is expected to ask the judge for a hearing on "stand your ground."
As for Zimmerman, O'Mara said after the court appearance: "He is tired. He has gone through some tribulations. He is facing second-degree murder charges now. He is frightened. That would frighten any of us."
"He has a lot of hatred focused on him right now," the attorney said. "I'm hoping that the hatred settles down now that we're moving forward."
