MEMPHIS, Tenn. (WMC-TV) - Memphis police will resume their search Wednesday for 86-year-old Elizabeth Ferguson, whose car was discovered in a field in Southwest Memphis on Tuesday.
Ferguson was last seen in May leaving her Memphis home for a routine doctor's appointment.
Police are treating her disappearance as suspicious.
A Tennessee game warden discovered her 1993 Mercury Sable on Tuesday on a dirt road in an area of Presidents Island called Ensley Bottoms.
Investigators are trying to figure out whether her car has been in the field for the entire six months that she has been missing.
The area is so remote, searchers could only access it by foot.
A bloodhound led the search Tuesday with the Memphis Police Missing Person's Unit, homicide detectives and wildlife officers.
Ferguson's daughter, Cheryl Ferguson Feeney, returned to Memphis Tuesday night.
She had just left Memphis on Sunday to fly back to her home in Seattle, after having spent the last six months in Tennessee searching for her mother.
"I just have to be here until I can find my Mom. That's all that is important," Feeney said.
