George Zimmerman, the man charged with fatally shooting Trayvon Martin surrendered to Florida authorities on Sunday after a judge revoked his bond. Zimmerman, 28, will remain at the Sanford facility until Circuit Judge Kenneth Lester decides if he should be free again, pending his second-degree murder trial. Judge Lester revoked bail on Friday after he learned Zimmerman had more money to his name than he initially reported and that he failed to give up one of his valid passports. Zimmerman is confined by himself in a single cell -- 67 square feet -- for his own protection, equipped with a toilet and two beds, according to the [Miami Herald](http://www.miamiherald.com/2012/06/03/2831483/after-bond-revoked-george-...). He has $500 in his jail account.
