The prosecutor investigating the shooting death of an unarmed Florida teenager, Trayvon Martin, has ruled out using a grand jury in the case.

This means that the prosecutors' office will alone decide whether to charge alleged shooter, George Zimmerman, with the crime which has captured national attention largely because of race.

Seventeen-year-old Martin was black and 28-year-old Zimmerman, who has not been charged, is white and Hispanic.
