Gwenn Marie Story was a 19-year-old American woman who was murdered in Las Vegas, Nevada, on August 14, 1979. Her body remained unidentified for 44 years before being identified via DNA analysis and genetic genealogy in December 2023. Prior to her 2023 identification, Story was nicknamed "Sahara Sue" and "Jane Las Vegas Doe" because her body was found near the Sahara Hotel in Las Vegas, at the intersection of Sahara and Las Vegas Boulevard. Developments indicated she may have used the name "Shawna" or "Shauna" when she was alive, though this proved unfounded.
Unidentified decedent, or unidentified person, is a corpse of a person whose identity cannot be established by police and medical examiners. In many cases, it is several years before the identities of some UIDs are found, while in some cases, they are never identified. A UID may remain unidentified due to lack of evidence as well as absence of personal identification such as a driver's license. Where the remains have deteriorated or been mutilated to the point that the body is not easily recognized, a UID's face may be reconstructed to show what they had looked like before death. UIDs are often referred to by the placeholder names "John Doe" or "Jane Doe". In a database maintained by the Ontario Provincial Police, 371 unidentified decedents were found between 1964 and 2015.

Elizabeth "Lisa" Ann Roberts, otherwise known as Precious Jane Doe, was an American homicide victim found near Everett, Washington on August 14, 1977, who was an unidentified decedent for 43 years until being identified on June 16, 2020. She had been picked up by a male driver while hitchhiking and killed after refusing sex. Her assailant had strangled her with a cord and then emptied his gun into her head, complicating identification. Roberts was a teen runaway who left her Oregon home in July 1977, less than a month before her murder. She was given the nickname "Precious Jane Doe" by Detective Jim Scharf, who began investigating the case in 2008. The detective was quoted as saying, "This young girl was precious to me because her moral decision from her proper upbringing cost her her life [...] I knew she had to be precious to her family too, so I had to find them. We needed to give her name back to her and return her remains to her family." Roberts was 17 at the time of her murder, though initial police estimations of her age were much older. Her body was found by blackberry pickers, and the medical examiner determined she had been dead for approximately 5 days before discovery. She was discovered fully clothed in a pastel tank top and denim cutoffs. As her identity remained unknown, Roberts' case was relegated as a cold case. In 2020, genetic testing via hair samples was used to locate her biological family, who led to her adoptive family.
