This is pretty scary!

Five women were shot and killed inside a clothing store at a suburban Chicago shopping center on Saturday in what police said appeared to be a robbery.
Police were searching for a lone gunman spotted outside the store by a witness, but said they had not identified him.
The victims were all found in the back of the Lane Bryant women’s clothing store in an area not frequented by customers, Tinley Park Police Sgt. T.J. Grady told reporters.
