Guthrie Genetic Genealogy

ABC News Crime and Terrorism Analyst Brad Garrett talks about how the Nancy Guthrie case has subsided from the headlines due to current events, the number of tips in the case has tapered off. That doesn't mean investigators aren't continuing to run down possible leads. One lead that did not pan out is DNA on a glove found about two miles from Nancy Guthrie’s home; it was traced back to a person who works at a nearby restaurant and “has nothing to do with the case.” However there still is no information about the unknown DNA found in the Guthrie house other than perhaps being run through CODIS. That leaves the possibility of the unknown DNA being compared to DNA in genealogy websites like GEDmatch and Family Tree DNA. How does this process work with various laws and restrictions on some of these ancestry databases and why might it take several weeks or longer to find a potential match?
