Police and the FBI returned to a home in Philadelphia’s Olney neighborhood as a months-long investigation involving at least seven missing women entered a new phase. Law enforcement sources told NBC10 the latest stage of the investigation at the Chew Avenue duplex will occur in phases. Inves tigators returned to the property Monday for a renewed examination of the scene, according to law enforcement sources. Additional work is scheduled for Oct. 5-16, when teams from multiple agencies, including the FBI, are expected to process the property and collect evidence. The first phase consists of investigators extensively photographing the property. Law enforcement sources said investigators were taking highly detailed photographs as they worked to uncover what happened inside the home. At least seven missing women are part of the investigation, five of whom are presumed dead, police announced two weeks ago. Investigators wearing white Hazmat suits went in and out of the property throughout the day. Yellow police tape blocked traffic from passing the home, while a Philadelphia Police Crime Scene Unit vehicle was parked at the end of the block.
