A gunman fatally shot five women in a robbery at a store in a suburban Chicago shopping center and fled, prompting police to sweep through neighboring shops as terrified customers watched, according to AP. The victims, including at least one employee, were killed at a Lane Bryant women's clothing store Saturday at the Brookside Marketplace, police Sgt. T.J. Grady said. Officers found the victims at the back of the store after getting an emergency call around 10:45 a.m., Grady said. Grady said robbery was believed to be the motive. Police searched for the gunman using dogs and a helicopter equipped with infrared sensors but concluded he left the stores off Interstate 80 southwest of downtown Chicago. In a Target discount store across the parking lot from Lane Bryant, terrified customers were herded to the front as police with pistols and rifles drawn went up and down the aisles and into storerooms searching for the gunman.
