From the below article:
Previously, DNA was used like fingerprints. Police would identify a suspect using traditional investigative means — canvassing the neighborhood, questioning witnesses, etc. — then collect a sample from their suspect. If it matched the DNA at the crime scene, it was good evidence they had found the perpetrator.
Genetic genealogy works the other way around. Police start with a DNA sample from the crime scene and enter it into public or commercial databases like GEDmatch, where people have voluntarily submitted their DNA, usually for genealogical purposes.
That allows police to find a relative of the perpetrator. Then they build that relative’s family tree. That family tree becomes a list of potential suspects.
I think this could be a bit of a tricky one. What do you think?
