George Zimmerman is back in jail.

Zimmerman, the onetime neighborhood watch volunteer charged with killing Florida teenager Trayvon Martin, turned himself in Sunday at the Seminole County jail in Sanford, Fla., two days after a judge ordered his $150,000 bond revoked when prosecutors said he wasn’t as poor as he had claimed.

He had been in hiding since he was released from jail on bond in April, and his attorney expects that another bond hearing will determine whether Zimmerman stays in custody until his expected trial in 2013.

Zimmerman, 28, is charged with second-degree murder in the Feb. 26 shooting of Martin, 17, who was unarmed. He has admitted shooting Martin during a confrontation at a gated community in Sanford, but says it was self-defense.

Sanford authorities initially decided not to charge Zimmerman, leading to more than six weeks of racially charged protests. Martin was black; Zimmerman is white and Latino.

Florida Gov. Rick Scott eventually appointed a special prosecutor, who filed the second-degree murder charge. Zimmerman has pleaded not guilty.

Circuit Judge Kenneth Lester said at a hearing Friday that Zimmerman had falsely represented his financial state when the $150,000 bond was granted. Zimmerman’s wife had testified in April that the couple had limited funds, but it was later revealed that the defendant had raised more than $200,000 from a website the family set up to solicit contributions.

Prosecutors said the Zimmermans “lied” about their financial state. “I don’t know what other word to use,” said prosecutor Bernie de la Rionda, the Orlando Sentinel reported. Lester sided with prosecutors and gave Zimmerman 48 hours to turn himself in, with a deadline of 2:30 p.m. EDT Sunday.

Defense attorney Mark O’Mara called the failure to disclose the additional funds a misunderstanding.

“The vast majority of the funds in question are in an independently managed trust, and neither Mr. Zimmerman or his attorneys have direct access to the money,” Zimmerman’s defense said in a statement on its website, which expressed hope that Zimmerman’s “voluntary surrender to Sanford police will help demonstrate to the court that he is not a flight risk.”

Prosecutors also accused Zimmerman on Friday of owning two passports and failing to surrender the second one at the bond hearing in April. Zimmerman had reported in 2004 that it had been lost or stolen, but in its motion, the prosecution quoted jailhouse calls between Zimmerman and his wife talking about the second passport.

“I have one for you in a safety deposit box,” she said, according to prosecutors, to which Zimmerman replied, “OK, you hold on to that.”

The judge dismissed that concern as the equivalent of someone who has lost a driver’s license, applies for a new one and then finds the old one, according to the Associated Press.
