Just over two decades later, in 2007, a DNA sample from her remains was reportedly transported to the University of North Texas Center for Human Identification, and the DNA was entered into the Combined DNA Index System and the National Missing and Unidentified Persons System for further investigation to determine her identity.
About six years later, in 2013, the bureau said, "[A] TBI agent and intelligence analyst revisited the case and began searching for new leads regarding the girl’s identity."
Then, in early 2022, the girl’s remains were brought to a private laboratory that analyzes human DNA called Othram, according to the bureau. Scientists were reportedly able to connect the remains to a possible relative in Indiana, and the bureau intelligence analyst found family members and contacted them. The bureau said one of the family members confirmed that they had a family member go missing from Indiana in 1978.
Familial DNA was reportedly submitted to the TBI Crime Lab in Nashville, and this week, the University of North Texas Center for Human Identification was able to identify the remains as those of Tracy Walker.
According to the bureau, special agents are working on the case to determine what led up to Walker’s death and how she ended up in Tennessee.
