Second man charged in fatal shooting of Chicago boy, 7

CHICAGO -- A Chicago man awaiting trial for murder has been charged in a July 4th shooting resulting in the death of a 7-year-old boy.

Cook County Assistant State's Attorney Jamie Santini told a judge that Jamal Joiner told an acquaintance he and Rasheed Martin, both street gang members, were aiming at a rival when Amari Brown was shot in the chest and a woman wounded.

Santini said the gang rivals had been feuding for months and had shootouts earlier that day as well as two other occasions weeks earlier. Joiner already is being held without for a murder stemming from one of the previous shootings. It wasn't immediately known if he has a lawyer.

The 21-year-old Martin of Chicago was arrested weeks after the shooting at a home in Superior, Wisconsin. He is being held without bond in Cook County Jail.
