The case centers on Mary Cobb and her daughter, Wynona Delvecchio, who were 104 and 83 years old, respectively, when they went missing in 2002.
Adair could not release information on what the new developments were, but said more information would be available in the coming days.
In early July, Wanda Faye Kiser, 61, was arrested in West Virginia on a 17-count indictment for second-degree felony forgery in connection with the disappearance of Cobb and Delvecchio.
Jasper police said in 2002 Kiser checked Delvecchio out of a nursing home she was residing in, and Delvecchio, in turn, checked her mother out of the nursing home. The women were last heard from in early 2002, when all communication and medical records stopped for both women, according to earlier reports in the Eagle.
In 2004, investigators for the federal railroad’s retirement system raised questions about the location of the women because of Cobb’s age. Kiser, who had relocated to West Virginia, reportedly used another elderly woman to impersonate Cobb.
After the woman was proven not to be Cobb, Kiser was charged and convicted of wire fraud.
