The gunman went farther into the 29,000-square-foot warehouse, and teams of officers went to look for him. The shooter was killed by officers, the chief said. A sixth officer hurt his knee and needed to go to a hospital. Authorities were still working Friday night to identify the deceased. There were about 30 people in the building at the time of the shooting. Four patients went to hospitals in Aurora, medical officials said. The chief said two wounded police officers were taken by air to trauma centers in Chicago, about 40 miles to the east.
Aurora, with about 200,000 people, is the second-largest city in Illinois, according to the city's website. Locals refer to Aurora as "City of Lights," a nod to it being one of the first American cities to implement a fully electric street lighting system.
Aurora has a strong music and arts scene, and is even the setting of the popular buddy-film "Wayne's World." Although a suburb of Chicago, Aurora has a long tradition of manufacturing.
