There are some people who believe that the Lady of the Dune's murderer removed her hands either because she had a criminal record or her fingerprints had been taken for another reason when she was alive. Recently, the Michigan Department of Corrections added more photos of wanted criminals to their website (they might have also added more criminals or revised their list of the MDOC most wanted escapees)

I noticed that Frankie McGraw, a woman who escaped from the Women's Huron Valley Correctional Facility in Ypsilanti on May 28, 1974, looks a lot like many of the composites that have been done of the Lady of the Dunes or at the as far as I can tell by the photo of her mugshot photo. With the exception of her age being a bit younger (23 years old) than the estimated age for the UID, the rest of her vital statistics seem close to those of the UID.
