TINLEY PARK (AP) — Saturday marks the fifth anniversary of the shooting deaths of five women at a clothing store in the Chicago suburb of Tinley Park, and investigators are still looking for the killer.

Three Tinley Park police investigators have worked full time to find the gunman. They have received nearly 6,700 leads, although only 87 came in 2012. Mayor Ed Zabrocki said the village has spent $1.9 million on the case. They've even had NASA enhance video.

A botched robbery attempt turned deadly on Feb. 2, 2008, when a man disguised as a deliveryman entered a Lane Bryant store. He forced the women into a back room, bound them with duct tape and shot them. A sixth woman was shot but survived.
