With leads running dry, BCI sent a tooth and a rib of the victim to the University of South Florida for an isotope analysis.
"Basically, how they described it to me is that you are what you eat," Molnar said.
The testing revealed something surprising, but also explained why investigators struggled to link any missing Ohio women to the case - the oxygen from atoms in Jane Doe's bones showed she was likely from southern states.
"The oxygen is consistent with the oxygen in drinking water values, in drinking water in that area," Molnar said.
Molnar began researching women, missing at least 11 years from the south, and so far she has provided 15 names and photographs to detectives.
All of the pictures will be shown to Grate after his trial in Ashland is over.
"Basically start all over. See if he recognizes anyone on this list," Bailey said.
Both Molnar and Bailey are promising not to give up until "Vicky" has a real name.
"We're not done. We want to make sure that this young woman is returned back to her family," Bailey said.
