I had to have Marcus arrested.

Marcus, Marie's own son, under arrest?

What was that all about?

When Dateline continues.

Did you kill your wife?

The case heads into court and Andre Jackson heads to the stand.

At last, he tells his own story.

I approached her in the bedroom and embraced her and kissed her.

Will a jury believe him?

That's all for now.

I'm Lester Holt.

Thanks for joining us.

Twelve years ago this week, we at Dateline posed a simple question on social media.

Have you ever known someone who has gone missing?

We did not expect that the response would be overwhelming.

Since then, Dateline has covered hundreds of missing persons cases for our online digital series and for the podcast it spawned, both called Missing in America.

I'm her only voice.

Each story is different.

However, when you speak with the people involved, the parents, the siblings, the friends, you will hear some common threads, heartbreak, confusion, and often a determination that does not fade with time.

Missing in America began as a way to shine a light on the stories of the missing.
