A "death investigation" | The Olney House, Part I

The house was a powder keg of incriminating, suspicious evidence. And there was a lot of it - bizarre items like chemical vats and urns, and tens of thousands of macabre files on hard drives. As one official described the material, "It's dark. Very dark." Months after launching an exhaustive search of a twin brick residence on a quiet block in North Philadelphia shared by a man and his late pornographer father, law enforcement in mid-August was finally ready to share a massive breakthrough - two women missing for years had been identified on video footage found in the home. The connection was strong enough to classify the case as a "death investigation," with officials foreshadowing this latest update was just the beginning.
