Video clues tie Olney 'mystery house' to two missing women believed dead

Philadelphia police say videos recovered from a West Chew Avenue house known as the 'mystery house' depict two missing women—Maribel Fresses (missing since 2018) and Gabriella Amarando (missing since 2012)—appearing alive and then dead, tying the residence to their deaths. The medical examiner has confirmed they are dead but cannot determine the cause. The investigation has involved more than 95 search warrants, and the digital evidence includes about 600,000 images and 70,000 videos. Separately, Eugene Horsch faces federal charges related to false FBI credentials, with a trial date set for September; investigators urge anyone who interacted with Horsch or his father to contact tips.
