The special prosecutor in Florida\'s Trayvon Martin case said she\'d release new information within 72 hours, as lawyers of the teen\'s shooter left the case. Angela Corey said in a statement late Tuesday she would hold a news conference by Friday but gave no details even about its location. She said she would alert the news media about the time and place 3 hours in advance. Corey said Monday she would not take the case to a grand jury and would instead make a decision about how to move forward herself. Martin was shot and killed by crime-watch volunteer George Zimmerman, 28, in a gated community in Sanford Feb. 26, as the 17-year-old was walking to the home of his father\'s girlfriend from a convenience store. Zimmerman, who is a white Hispanic, told police he shot the unarmed black teen in self-defense. The decision by local authorities not to bring charges against the Zimmerman set off a national outcry and led to a decision by Florida Gov. Rick Scott to assign Corey, the state attorney for the Jacksonville area, to take over the case March 22. The US Justice Department also opened an investigation. A grand jury had been set to meet Tuesday in Sanford, about 20 miles northeast of Orlando. Corey\'s Tuesday announcement came several hours after two lawyers for Zimmerman held a news conference in Sanford to say they withdrew from the case after not hearing from him since the weekend. Craig Sonner and Hal Uhrig also said Zimmerman had reached out to Corey for a meeting against their advice and had contacted Fox News Channel host Sean Hannity. \"We were a bit astonished\" by the call to Corey\'s office, Uhrig said. Corey would not speak with Zimmerman without his lawyers present, Sonner and Uhrig said. But Zimmerman told Corey\'s office Sonner and Uhrig were merely his legal advisers, Uhrig said. The lawyers would not reveal the substance of the call to Hannity. Hannity, a conservative political commentator and author, recently interviewed Zimmerman\'s father and asked questions The Miami Herald termed \"sympathetic,\" such as, \"Is it true George mentored a black teenager?\" Zimmerman has also started a Web site, therealgeorgezimmerman.com, asking for money to deal with the \"life-altering event\" that, he wrote, forced him \"to leave my home, my school, my employer, my family and ultimately, my entire life.\" Sonner and Uhrig said they had been unaware of Zimmerman\'s plans to create the site. They had been working with Zimmerman\'s father to start a legal-defense fund in the father\'s name, they said. Martin\'s father, Tracy Martin, scoffed at the wording of Zimmerman\'s site, noting that his son suffered not a life-altering event, but \"a life-ending one,\" the Herald said.
