Fingerprint comparisons are a disappointment for Kansas City authorities still hoping to identify Precious Doe, the decapitated little girl found more than a year ago.Kansas City police say the palm print sent them by authorities in Miami, Florida, does not match the print of Precious Doe. Investigators had wondered if Precious Doe is a missing five-year-old Miami girl. The authenticity of the palm print remains under question, though. The mother of the missing Miami girl is being asked to supply DNA samples that can be compared to those from the girl found in Kansas City.
