An official with knowledge of the investigation told The Associated Press that a prosecutor will announce charges against George Zimmerman on Wednesday at 6 p.m.

The official didn't know the charge and spoke on condition of anonymity because he wasn't authorized to release the information. The official also said that authorities know where Zimmerman is.

State Attorney Angela Corey says she will release new information on the case on Wednesday afternoon but didn't elaborate.

Zimmerman admits to shooting 17-teen-year-old Martin in February, but claims he acted in self-defense. 

The case has sparked protests and calls for Zimmerman's arrest as well as opening a dialogue about Florida's so-called "stand your ground law," which gives people a wide latitude to claim self-defense in altercations.
