The Mohave County Sheriff's Office has identified human remains found north of the Colorado River in northwestern Arizona.
They say the remains are those of 63-year-old Susan Marie McFalls from Littlefield.
The county Medical Examiner's Office was able to identify the remains using medical records and a medical device the woman had.
The remains were found on Oct. 18 near the Virgin River Gorge in the Arizona Strip area near the Utah border.
Authorities say another body was found in the same area, but hasn't been identified yet.
The remains were forwarded to the FBI crime lab for scientific examination.
McFalls and her husband Jerry went missing in January.
Investigators say the couple's phones, identifications and other personal items were still inside their Littlefield home near the Virgin River Gorge.
