SANFORD, Fla., April 11 (UPI) -- A Florida special prosecutor plans to charge George Zimmerman in the shooting death of Trayvon Martin, an official told The Washington Post Wednesday.

An unnamed law enforcement official close to the investigation told the Post special prosecutor Angela Corey plans to make the announcement as early as Wednesaday, but it was not immediately clear what charge Zimmerman would face.

The 17-year-old Martin was shot and killed on the night of Feb. 26 by neighborhood watch member Zimmerman in Sanford, Fla. Zimmerman claimed he was acting in self-defense, and citing the state's "stand your ground" law. Police did not charge him.

Earlier, Zimmerman's former lawyers said they stopped representing him when he talked to Florida prosecutors without consulting them.

"We're simply announcing that the relationship no longer exists, based on learning from the special prosecutor directly that he had contacted them," lawyer Hal Uhrig told NBC's "Today" show. "When they said we won't talk to you without your lawyers, he said, 'Well, they don't really represent me now, they were just my legal advisers so I can come in and talk to you.'"

Corey, named as a special prosecutor in the shooting death, has said she plans to make an announcement by the end of the week on how she will proceed with the case. There has been a national uproar over the decision by local prosecutors not to charge Zimmerman for killing the unarmed teenager.

Corey reportedly refused to talk to Zimmerman.

Attorney Uhrig said he and Craig Sonner would "welcome" a call from Zimmerman.

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 Zimmerman, 28, in a gated community in Sanford as the teenager 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 African-American teen in self-defense.

The decision by local authorities not to bring charges against 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 U.S. Justice Department also opened an investigation.

A grand jury had been set to meet Tuesday in Sanford, about 20 miles northeast of Orlando.

The lawyers said Tuesday that Zimmerman also had been in touch with Sean Hannity without consulting them. 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.
