SANFORD, Fla. (AP) - The special prosecutor in the Trayvon Martin shooting case says she will make an announcement about the case within 72 hours.

In a statement released late Tuesday, Prosecutor Angela Corey didn't specifically say what the announcement will be. She is deciding whether to charge George Zimmerman with a crime for fatally shooting the 17-year-old Martin.

The neighborhood watch volunteer says he was acting in self-defense when he shot the unarmed Martin on Feb. 26. Martin's parents say Zimmerman attacked their son. The case has raised questions about racial profiling.

Martin was black; Zimmerman's father is white and his mother is from Peru.
