On April 26, 2018, her body was exhumed. DNA samples were then sent across the country. The results were compared to other DNA profiles in an attempt to identify her or any possible relatives.

Jane Doe was identified as Amy Yeary of Rockford, Illinois. She would have been 18-years-old at the time of her death. Yeary was positively identified after three separate DNA comparisons. The comparisons were done with her mother, her sister and dental x-rays.
