Bones have been recovered from a Philadelphia home at the center of an investigation involving several missing women, sources told our sister station WPVI-TV. Sources said the Medical Examiner's Office was called Thursday to recover bones from the home in Philadelphia's Olney section.

Sources said the condition and origin of the remains are not yet known.

The bones will be sent to a laboratory for forensic examination to determine whether they are human and, if so, whether they may be connected to the ongoing investigation.
