The immediate area around Lane Bryant is still closed.
"We're all just thinking that this is a safe neighborhood. You just think it couldn't ever happen here. But, we've learned it can happen anywhere," said Alysia Lambert, shopper.
Mayor Zabrocki said the village is talking with the mall's owner to determine if it will install surveillance cameras and put security personnel in place. The mall has decided to allow the village to have police presence.
