Florida special prosecutor will charge George Zimmerman in the Trayvon Martin case.

WaPo reports, based on information from "a law enforcement official close to the investigation."

It was not immediately clear what charge Zimmerman will face.

UPDATE: The charge is second-degree murder:

“We did not come to this decision lightly,” [Angela B.] Corey said. She added, “Let me emphasize that we do not prosecute by public pressure or by petition.”

“We will continue to seek the truth about this case,” she said.
