Three New Jersey men have been charged in the 2009 beating death of a middle school teacher who authorities say was a victim of mistaken identity.

The charges were announced Thursday by the Monmouth County Prosecutor's office, which says they acted on a tip.

Jonelle Melton's body was found in September 2009 inside her Neptune City apartment. The 33-year-old taught at a middle school in Red Bank.

Acting Monmouth County Prosecutor Christopher Gramiccioni (grah-mee-chee-OHN'-ee) says James Fair, Ebenezer Byrd and Gregory Jean-Baptiste have been charged with murder, robbery and other offenses.

Gramiccioni says the three had planned on robbing a different apartment in the same complex.

It wasn't immediately known if the three had retained attorneys.
