Battle represented himself at trial. He is charged along with two others, Menelik Jackson and Jaquan Washington. The three are being tried separately, and Jackson and Washington have not yet gone to trial.
Rivera and two other people, a man and woman, were sitting in their vehicle after leaving the Stout Barrel House nightclub on March 23 at about 3:30 a.m. in the 700 block of North Clark Street when two men fired into the vehicle before running off.

Rivera was shot in the chest, arm and mouth, police said. He was pronounced dead at Northwestern Memorial Hospital. A second man, also age 23 and not an officer, sustained wounds to his chest and arm, and was also taken to Northwestern in critical condition. He was sitting behind Rivera.
Investigators said Rivera may have been mistaken for someone in another group that had fought with the suspects hours earlier, or may simply have been targeted because he was Hispanic.
