Trayvon Martin: George Zimmerman released on $1 million bail Defence attorney Mark O'Mara had said that Zimmerman and his family could not post the $1 million bond, which typically would require a deposit of 10 per cent cash and the rest secured by collateral, without donations from supporters. It was not immediately clear how the Zimmermans came up with the bond money. Shawn Vincent, who manages the website for O'Mara, told Reuters on Friday the largest donation overnight was $1,000, and that most contributions ranged between $10 and $25. Since May 3, when O'Mara took control of Zimmerman's defence fund-raising, donations have averaged $500 to $1,000 per day, he said. The defence website said Zimmerman's security team had established a temporary safe house for him to go to upon his release from jail but that a permanent location was being sought. Zimmerman is charged in the Feb. 26 shooting death of 17-year-old Martin in a gated community in the central Florida city of Sanford. Martin's killing drew national attention because police initially declined to arrest Zimmerman. They cited Florida's "Stand Your Ground" self-defence law and Zimmerman's claim that he used deadly force because he believed his life was being threatened by Martin. Zimmerman, 28, was later arrested on second-degree murder charges, which carry a penalty of 25 years to life in prison.
