Police did not say exactly what Battle’s role was in the shooting, but said he was there when Jackson shot the victims.

Police said Jackson and another man got into a fight with a group of Hispanic men on a party bus at the flagship McDonald’s restaurant at 600 N. Clark St. about an hour before the shooting.

Chief of Detectives Melissa Staples said Jackson was caught on video running from the McDonald’s, and coming back after the party bus had left. The other man involved in the fight was not in custody Monday morning, but police said they know who they are looking for.

Superintendent Eddie Johnson said Jackson and Battle then started searching the area for any Hispanic person they could find. He said they could face additional hate crime charges as a result.

“In an act of cowardice, Mr. Jackson went to get a gun to settle this petty dispute, which resulted in him murdering the first Hispanic man that he came in contact with,” Johnson said.
