(CBS/AP) SANFORD, Fla. - George Zimmerman' has returned to a Florida jail, after a judge revoked bond for the man accused in the shooting death of Trayvon Martin.
Zimmerman wore a white plaid shirt and jeans when he arrived at the jail in a white unmarked minivan with a police official. He did not answer questions from reporters.
Zimmerman's lawyer said he hopes his client's voluntary return to Florida to turn himself in will show that he's not a flight risk.
A judge revoked Zimmerman's bond last week, suggesting he and his wife had not been honest about their finances. The neighborhood watch volunteer is charged with second-degree murder in the fatal shooting of unarmed 17-year-old Trayvon Martin.
Zimmerman's lawyers say their client returned to the state to meet this afternoon's deadline. They say they will ask for a new bond hearing.
During a bond hearing in April, Zimmerman and his wife indicated they had limited funds. But prosecutors say Zimmerman had raised thousands through a website he had set up for his legal defense.
His lawyers said in a press release that the money Zimmerman has raised is in an independent trust and cannot be directly accessed by Zimmerman or his attorneys.
The press release on the website said the deadline for his surrender was 2:30 p.m. Sunday.
Zimmerman has pleaded not guilty to the second-degree murder charge. He maintains he shot Martin in self-defense under Florida's so-called "stand your ground" law because the teen, who was unarmed, was beating him up after confronting Zimmerman about following him in a gated community outside Orlando.
Zimmerman's credibility could become an issue at trial, legal experts said, noting the case hinges on jurors believing Zimmerman's account of what happened the night in February that Martin was killed.
Zimmerman wasn't charged in the case until more than a month after the shooting. Protests were held across the nation, and the case spurred debate about whether race was a factor in Zimmerman's actions and in the initial police handling of the case. Martin was black; Zimmerman's father is white and his mother is from Peru.
Police in Sanford did not immediately arrest Zimmerman, citing the Florida law that gives wide latitude to use deadly force rather than retreat in a fight if people believe they are in danger of being killed or seriously injured.
The questioning of Zimmerman's truthfulness by the judge on Friday could undermine the defendant's credibility if it is brought up at trial. It also may complicate how his defense presents him as a witness, said Orlando-area attorney Randy McClean, a former prosecutor.
"The other key witness, unfortunately, is deceased," McClean said. "Basically, Zimmerman is going to be asking the jury to believe his version of the facts. ... As the case stands now, his credibility is absolutely critical to the case."
Jail authorities in central Florida, where the case arose, said Zimmerman had not turned himself in there by early Sunday. He must do so by Sunday afternoon.
Zimmerman went into hiding in the weeks after the shooting and his exact whereabouts since he bonded out of jail remain unclear. It was not immediately clear exactly where Zimmerman would surrender.
Witness accounts of the rainy night that Martin was shot are spotty. There is no video of the fight, though photos released by prosecutors show Zimmerman with wounds to his face and the back of his head.
Zimmerman's credibility would be important if his attorney, Mark O'Mara, tries to get a judge without the jury to dismiss the charges based on the law, said Orlando defense attorney David Hill.
"If he was in on something that was not truthfully revealed to the judge, when there is a `stand your ground' hearing, of course you're going to second-guess him," Hill said.
Both McClean and Hill said O'Mara would be able to challenge the admissibility of the bond revocation at trial by questioning its relevance.
Zimmerman was arrested 44 days after the killing, and during a bond hearing in April, his wife, Shellie, testified that the couple had limited funds available. Zimmerman took the stand at the hearing and apologized to Martin's parents.
Prosecutors pointed out in their motion that Zimmerman had $135,000 available then. It had been raised from donations through a website he had set up. They suggested more has been collected since and deposited in a bank account.
Shellie Zimmerman was asked about the website at the hearing, but she said she didn't know how much money had been raised. Circuit Judge Kenneth Lester set bail at $150,000. The 28-year-old was freed a few days later after posting $15,000 in cash — which is typical.
Prosecutor Bernie De la Rionda complained Friday, "This court was led to believe they didn't have a single penny. It was misleading and I don't know what words to use other than it was a blatant lie." The judge agreed and ordered Zimmerman returned to jail by Sunday afternoon.
The defense countered that Zimmerman and his wife never used the money for anything, which indicated "there was no deceit."
The judge said he would schedule a hearing after Zimmerman is back in custody so he could explain himself.
Benjamin Crump, an attorney for Trayvon Martin's parents, Tracy Martin and Sybrina Fulton, said his clients have always said Zimmerman should remain in jail until trial.
