It could be you — you know, one of those people who are sweating the genealogical DNA fishing trips police are using to close out cold cases?
The number of people who think they literally got away with murder long ago is dwindling. You might be parked in a nursing home somewhere and — voila — the cops come calling with a murder warrant.
Police send decades-old DNA samples to genealogical labs, where they’re compared to millions of people who voluntarily surrendered their genetic footprint, gradually narrowing the pool of suspects to just a few people.
If the match puts them in the right neighborhood, it’s only a matter of following the suspects around, gathering up something containing DNA that is thrown away, and eventually forcing you to explain how your DNA came to be on/in the body of a murder victim.
