"Multiple" victims were found Saturday at a clothing store in a strip mall of a Chicago suburb, but there was no sign of the shooter, authorities said. They did not immediately confirm a report that four people had been killed. Police Sgt. T.J. Grady said officers responding to a 911 call about a shooting at the Brookside Marketplace at about 10:45 a.m. found the shooting victims inside a Lane Bryant store. Grady refused to give other details at a news conference or take questions, but said the attacker had apparently left the area in the suburbs southwest of downtown Chicago. "No motive has been established," Grady said. "Every store was immediately canvassed and a search by air, too, has given us every indication that the offender has left the scene."
