TALLAHASSEE, Fla. (AP) - The Florida prosecutor who charged George Zimmerman with second-degree murder is going to spend another four years in office.

Angela Corey on Friday won a new term after no one stepped forward to challenge the Republican in this year's election. Qualifying ended at noon.

Corey was first elected in 2008 as state attorney for the judicial circuit that includes Clay, Duval and Nassau counties in northeast Florida.

The 57-year-old prosecutor is known for her tough tactics, locking up criminals for long sentences and not negotiating easily on plea bargains.

Gov. Rick Scott appointed Corey in late March to oversee the investigation into the death of Trayvon Martin.

The governor named Corey after the local prosecutor for the central Florida county where the shooting happened, Norman Wolfinger, volunteered to recuse himself.
