The Daily

This week, “The Daily” is revisiting some of our favorite episodes of the year and checking in on what has happened since the stories first ran. Today: the unexpected story of how family history websites have been used by law enforcement to track down suspects and win convictions — and why retroactive regulation won’t be able to reverse the trend. Guest: Heather Murphy, a reporter at The New York Times who spoke with CeCe Moore, a genetic genealogist, and Curtis Rogers, a creator of the genealogy website GEDMatch.
