Problem: Cold case investigations have improved a lot now, and it's all thanks to the new forensic tools. Two advances are forensic genetic genealogy and better DNA testing on old evidence. Genetic genealogy lets the investigators use DNA profiles with public family tree databases to find relatives and possible matches even if that person isn't in any police databases (Guerrini et al., 2021). At the same moment, better lab methods now make it possible to get DNA from samples that were once too damaged to use, such as old bones and rootless hairs. An example is the case of "Precious Jane Doe," whose remains were found in Everett Washington in 1977. For many years no one could identify her. Then in 2022 her case was solved when scientists pulled DNA from her hair samples and then used genealogy databases to find her family. She was identified as Elizabeth Ann Roberts (Hutton, 2020). This shows how DNA methods and genealogy together can give answers to those families and close the cold cases that at first seemed unsolvable for many years.
