Name: Jane Doe - Yosemite Summit Meadow

Location: Yosemite National Park

Date: Fall of 1981 to Spring of 1983

Suspect Info: Henry Lee Lucas (deceased)

Case Info: The partial remains of a homicide victim were found in Yosemite National Park's Summit Meadow along Glacier Point Road in 1983. NPS investigators determined that Henry Lee Lucas had information about the murder that had not been made public and could only be known by the person who committed the crime. Lucas died in prison in 2001. Special Agents with the NPS Investigative Services Branch continue to investigate this case in hopes of identifying the victim. Lucas had told investigators that he picked up the woman between Fresno, California and Yosemite National Park along California Highway 41 in the fall of 1981. The woman was a white female that Lucas described as 5'05" to 5'06" tall with long, straight blonde to light brown hair. She weighed about 100-125 pounds, and wore silver rings on both hands. Lucas estimated her age as between 17-20 years of age, but a forensic anthropologist placed her between 20-23 years of age at the time of her death. She was of European ancestry, had a slight overbite, and a long, narrow face. The images are from a facial reconstruction of a skull without a lower jaw. The chin is generic and the hair could be any style. If you have information that could help investigators identify this young homicide victim, please contact us.
