The Hunt for the Chicago Strangler

I absolutely love the reason as to why this documentary was created and brought to life. The unfortunate, brutal murders of these innocent, beautiful QUEENS is a travesty and is BEYOND overdue. We all know why this has been swept under the rug and disregarded...the only issue I have with this documentary is how it somewhat goes on a tan grant and introduces soooo many people who sort of have nothing to do with tracking down the perpetrator(s). There's a point where-after realizing that this was happening and no one has been captured-it 1) makes me furious and 2) loses my interest. It's as though, now that this is getting publicized, what is the next step???? How is the community and society doing their due diligence to get some answers..????? Where do we go from here??
