Genetic genealogy can help solve cold cases. It can also accuse the wrong person. – PBS Science November 7, 2019

I saw this recently on PBS Science –

Genetic genealogy can help solve cold cases. It can also accuse the wrong person.: https://www.pbs.org/newshour/science/genetic-genealogy-can-help-solve-cold-cases-it-can-also-accuse-the-wrong-person. This is a point that cannot be stressed enough.

A couple of key points from the article; it’s a good read:

Berkman added that police departments need to be more transparent about when and how they’re using genetic genealogy and other DNA information to prosecute someone.
