Three days later, on July 20, Coleman and Brown were arrested in Evanston. As they walked westward across an intersection, they passed immediately in front of a motorist who was from Coleman's neighborhood in Waukegan. The motorist drove north to a gas station and notified the police. The couple were soon spotted sitting on portable bleachers in empty Mason Park. As two police sergeants approached Coleman, Brown was observed walking away toward the rear of the park. Two other officers stopped Brown as she tried to exit the park, searched her, and found a gun in her purse. The pair were taken into custody without incident and transported to the Evanston police station, where both were identified by their fingerprints.
