Missing N.C. girl, Zahra Baker.

The prosthetic leg that authorities found last week has been linked to missing 10 year old Zahra Baker.

Authorities have stated that medical records from Australia have confirmed that the serial number matches that of the leg the missing NC girl was fitted with.  Zahra received the leg in Australia at the age of five after a battle with bone cancer.

Investigators found the leg off of Christie Road in a brushy area near a home where stepmother, Elisa Baker, once resided. According to police the family has lived in several homes and there is definite answer as to how long this home was occupied by Baker.

Authorities continue to search for Zahra although it is presumed she is dead. Her father reported her missing on October 9, though no one but family has seen her since September 25.  On October 12, Hickory Police canceled the Amber alert and switched from a missing persons search to a homicide investigation.

Elisa Baker was arrested on October 10 for charges unrelated to the case. She later confessed to writing a fake ransom note that was found near a fire at the Baker home the day Zahra was reported missing. She was charged with obstruction of justice. A Catawba County Grand Jury officially indicted Elisa Baker Monday on the felony obstruction of justice charge. Police have stated that she is currently cooperating with the investigation.

Father, Adam Baker, was arrested last week on unrelated charges.  He posted bail on Thursday. It is unknown whether he is continuing to help in the investigation.
