The Adelson children take the stand. A missing woman's husband is arrested. And a deep dive on DNA.

Listen to this episode from Dateline NBC on Spotify. Two of Donna Adelson's children testify this week for the prosecution.

Plus, a former prosecutor on DNA's uses and pitfalls. Find out more about the cases covered each week here: www.datelinetruecrimeweekly.com To learn more about Dateline LIVE in Nashville on Sept. 28, and to get tickets, go here: https://www.nbcnews.com/dateline-event Hosted by Simplecast, an AdsWizz company.
