Official: Charges to come in Trayvon Martin case

SANFORD, Florida - A special prosecutor has confirmed that there will be a 6 p.m. news conference regarding the investigation of the shooting death of Trayvon Martin.

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

Her announcement came not long after another law enforcement official said that charges are being filed against George Zimmerman, who shot Trayvon.

The official with knowledge of the investigation says Zimmerman's arrest is also expected soon.

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

Zimmerman has asserted since the Feb. 26 killing that he shot the 17-year-old in self-defense after the two fought. The case has sparked protests and calls for Zimmerman's arrest.
