Police on Monday were still searching for two of three men who attempted to rob a jewelry store a day earlier at Oakbrook Center mall in Oak Brook.
The trio entered the C.D. Peacock Jewelry store around 3:40 p.m. One man was armed with a four-pound sledgehammer he used to smash a display case, police said.
An armed security guard intervened and told the man to put down the sledge hammer, but he refused and advanced toward the guard, police said. The guard then fired his gun and shot the man in the abdomen, authorities said.
