@cbsphiladelphia: Investigators at the Olney "house of horrors" owned by Eugene Horsch have found numerous areas where there could be potential DNA evidence, police sources confirm. Crime scene investigators sprayed the chemical luminol throughout the home on Chew Avenue linked to several missing women who are feared dead. The chemical lights up when it comes into contact with areas where blood has been present. Now several locations within the home will undergo further testing. Stay with CBS News Philadelphia for the latest on this investigation. #philly #olney
