Armando Diaz was 16 when he died on March 17, 2007, after a birthday party on Indianapolis’ Northside. A junior at Pike High School and a member of St. Monica Catholic Church, Diaz—known as JoJo—was riding as a passenger in a Ford Taurus that was chased and fired upon by occupants of a silver SUV, reported by police as a Honda CRV. The SUV’s occupants used what investigators described as an assault rifle; the Taurus was struck by at least four bullets. The chase ended in a crash that killed Diaz and 18-year-old Fausto Ramon Lopez.

Two other 18-year-olds, Cesar Garcia and Myra Raymundo, were hit by gunfire while fleeing in another vehicle; Garcia suffered a gunshot wound to the head. Police suspected gang rivalry in the violence, but available reports do not name any suspects, and investigators faced reluctance from witnesses to come forward. If anyone knew JoJo, Fausto, or saw the vehicles involved that night, any information could help clarify what happened.
