5 missing women are linked to Olney home in Philadelphia. Here's what we know.

Key Points:

• Philadelphia police are investigating a home in the Olney neighborhood linked to at least five missing women, focusing on Eugene Horsch and his late father R.C. Horsch, who lived there.
• Eugene Horsch was arrested in June on firearms, drug, and forged document charges after a park ranger discovered a missing woman's ID in his car.
• A search of the Olney home uncovered dangerous chemicals, a marijuana grow operation, over 1 million digital images and videos depicting multiple women, some injured or possibly deceased, and 120 pieces of ballistic evidence.
• Police identified 58 people in the images; 16 are alive but uncooperative, 25 have scheduled interviews, and five women believed to be missing are linked to the home, including Gabrielle Amarando, Maribel Fresses, Nicole Fusaro, Amy McHale, and Blair Tonzelli.
• While five urns believed to contain human remains were found, no bodies have been confirmed at the house; some videos show disturbing scenes involving R.C. Horsch, but authorities caution that evidence is still being evaluated to determine what is real versus staged.
