Police found a prosthetic leg that could belong to missing 10-year-old Zahra Baker.
Investigators located the leg Tuesday afternoon during their search of Christie Road in Caldwell County.
Hickory Police Chief Tom Adkins announced the recovery Wednesday afternoon during a press conference.
Adkins said investigators will use serial numbers printed on the prosthesis to confirm if the leg belonged to Zahra, who lost her lower left leg after suffering bone cancer.
Zahra also wore hearing aids due to hearing loss from cancer treatment, but the hearing aids were located at the Baker house in Hickory when Zahra's father, Adam Baker, reported her missing Oct. 9.
Zahra's prosthesis was fitted in Australia, and Adkins said confirming the serial numbers could "take some time."
The leg was found on the ground in a brush pile in Caldwell County and wasn't buried, according to Adkins.
Adam Baker was bonded out of jail Wednesday about 5 p.m., according to Catawba County Chief Deputy Coy Reid.
Reid said a bondsman signed for Baker's $7,000 secured bond.
Both Adam and Elisa Baker were arrested during the search for Zahra.
Adam Baker was arrested early Monday morning at Hickory Police Department on outstanding warrants and was transported to Catawba County jail.
Elisa Baker was arrested Oct. 10 on charges unrelated to Zahra's disappearance.
Elisa Baker was later charged with felony obstruction of justice after she admitted to writing a phony ransom note. She is in Catawba County jail under a $97,200 bond.
The discovery of the prosthesis comes one day after police announced the recovery of a mattress that could have belonged to Zahra.
Employees at the Foothills Environmental Landfill in Caldwell County discovered the mattress Tuesday while regrading a site searched last week by investigators.
Adkins confirmed Wednesday that the mattress contains DNA evidence and will be processed for additional information.
Adam and Zahra Baker moved to North Carolina from Australia in 2008 after Adam met and married Elisa Baker, whom he met online.
Hickory Police announced Tuesday in a press release that Elisa Baker, with her attorneys, provided police with information in the search for Zahra.
Adkins wouldn't comment Wednesday about whether Elisa Baker's information led investigators to locate the prosthetic leg on Christie Road.
Investigators continued to search Wednesday for clues in Zahra's disappearance through another search of the Baker home, located at 21 21st Ave. NW in Hickory. The house was sectioned off as police searched the area. Adkins would not comment Wednesday on the search of the Baker house, saying only that leads in the investigation brought police back to the residence.
Investigators previously searched the Baker house days after Zahra was reported missing. A canine trained in the recovery of human bodies gave a positive alert during the search for the presence of human remains.
Search crews later returned to the Baker house Oct. 15 for additional information.
