Rebecca Sue Hill, described in records as a white teenager aged 16 or 17, disappeared from Arkansas in 1981 but was not entered into national missing-person databases at the time because her family mistakenly believed different human remains found in Little Rock were hers. Her true fate remained unknown for decades.

Partially skeletonized remains found April 18, 1984, in a wooded area near Lake Dorr in Altoona, Florida (Ocala National Forest), were long classified as Judy Doe. In December 2024 genetic genealogy confirmed Judy Doe as Rebecca Sue Hill.

Her death is ruled a homicide. Investigators have considered a possible connection to Michael Ronning, who was active in the area and later provided information about a body in Lake County; Ronning died in prison in 2022. No arrests have been announced and the investigation remains open. If anyone knew Rebecca, saw her in Arkansas in 1981, or has information about travel through Lake County in early 1984, please come forward.
