Six months after he was fired, a 36-year-old man cornered former co-workers in the Chicago auto parts warehouse where he had worked, killing six of the company's nine employees, including two of its owners, on August 27.
Using a .380-caliber semiautomatic handgun, the man traded gunfire with Chicago police inside and outside of the Windy City Core Supply warehouse before being killed by a police bullet. There is a ban on handguns in Chicago.
