On Saturday morning, searchers found skeletal remains and what appears to be a woman's shoe and clothing about 200 yards from where a car belonging to Elizabeth Ferguson, an 86-year-old woman missing since May, was discovered last Tuesday.
The bones were discovered by deputies during a four-wheeler ground search of the area.
The Shelby County Medical Examiner's team collected and transported the remains to the forensic lab for further examination and identification.
Ferguson's 1993 Mercury Sable was discovered by a wildlife officer last week on a dirt road in Ensley Bottoms, a remote, wooded area of Southwest Memphis.
Ferguson was last seen six months ago, leaving her Berclair home to go to a doctor's appointment.
Her family says she suffered from high blood pressure and was in the early stages of dementia.
Investigators say they don't suspect foul play. They believe Ferguson drove herself to the end of Riverport Road, parked her car and then wandered into the woods.
