A gunman shot and killed five women in a clothing store at a suburban Chicago strip mall Saturday, CNN reported.
The motive for the shooting at the Lane Bryant store was a robbery that at some point went rather poorly, police said.
All of the victims -- ranging in age from 22 to 37 -- were found in a back room of the store, he said. Their identities were not released.
"This is a very serious and sensitive investigation," Tinley Park Police Chief Michael O'Connell said Saturday evening.
At least one of the victims was a Lane Bryant employee, O'Connell said. The store did not have a security camera, he added.
