Kate Snow

You were just tireless with your efforts for all these families and for the people who don't have a voice anymore.

Thank you.

If you have any tips or information you want to share about the Olivia Lone Bear or Nancy Guthrie cases, you can call the FBI at 1-800-CALL-FBI.

That's 1-800-225-5324.

We will post that number in the episode description.

We're thinking about all the families out there who are missing loved ones, and especially our friend and colleague, Savannah.

That is it for this episode of Dateline True Crime Weekly.

Coming up this Friday on NBC, the Winter Olympics are over and we have an all-new episode of Dateline.

When a loving father suspiciously dies, his family's decade-long fight for justice begins with the most unlikely piece of evidence, a hairbrush.

You basically have a detective mind at this point.

Watch Blaine's episode, Malice, this Friday at 9, 8 central on NBC.

Thanks for listening.
