In 2020, the Walker County Sheriff's Office partnered with
Othram Incorporated to attempt to identify Walker County Jane Doe via
genetic genealogy. Initial attempts to extract usable genetic materials from her remains were unsuccessful, but testing on her preserved
tissue samples yielded usable DNA, which was used to generate a
genetic profile of the victim and construct a family tree. Using this family tree, the victim's living relatives were identified and located. DNA swabs from these individuals were used to confirm the identity of Walker County Jane Doe in 2021. On November 9, 2021, the Walker County Sheriff's Office publicly announced the identity of Walker County Jane Doe as 14-year-old Sherri Ann Jarvis, who had run away from
Stillwater, Minnesota in 1980. Her identification had previously been announced in late September 2021 by
forensic artist Carl Koppelman, who had produced several forensic reconstructions of the victim, and who announced that her identity was temporarily being withheld to give her family sufficient time to grieve privately. Jarvis was known as "Tati" to her friends. She had been removed from her home and placed under the state's custody at age 13 due to habitual
truancy and had run away shortly after her 14th birthday. Her final contact with her family was in the form of a letter penned to her mother from
Denver in August 1980. In this letter, Jarvis indicated that she was frustrated with being placed in state custody but intended to eventually return home. At this formal announcement, a statement from her family was read, expressing gratitude for "the dedication" of all who had worked to identify Jarvis and to "provide [the] long-awaited, albeit painful answers" to their questions as to her whereabouts, adding that they took comfort from the fact she had been identified. This statement also thanked those who had visited her grave while she had remained unidentified and emphasized the family's wish for her murderer(s) to be brought to justice. and investigators have stated discovering Jarvis's identity has given them "some positive leads" of inquiry that they are actively pursuing. ==Other hypotheses==
