DNA is really an amazing tool!

"DNA and genealogy technology used to identify the woman in the Miami County case known as the Buckskin Girl in 2017 was credited with identifying the remains of a missing woman from Miami County in the 1980s whose remains were found in Illinois.
Brenda S. Black had been missing since the early 1980s when she last had contact with her family. Because of news coverage on the Buckskin Girl case, and additional use of DNA, Black was officially identified in a cold case death investigation in Will County, Illinois from 1981, Miami County Sheriff Dave Duchak said in a media release.
Brenda’s brother, Allie, approached the Miami County Sheriff’s Office in 2015 after watching news coverage on the Buckskin Girl, thinking she might be his missing sister. Allie submitted a DNA test to compare against the DNA profile of the Buckskin Girl, Duchak said."
