The first trial stemming from the shooting deaths of three friends in a Newark schoolyard is set to begin Tuesday afternoon with opening statements. Rodolfo Godinez (goh-DEE'-nez) is the first of six defendants to go to trial in the 2007 killings of Dashon Harvey, Iofemi (yoh-FEM'-eeh) Hightower and Terrance Aeriel. A fourth victim survived the attack and is expected to testify. Prosecutors say the defendants attacked some of the victims with a machete before shooting them execution-style. The crime brought national attention to Newark's violence problem and led to numerous measures that have been credited with helping lower the crime rate in New Jersey's largest city.
