I'm Cheryl McCollum, host of the brand new Cold Case Podcast, Zone 7.

We're going to be talking to family members, detectives, prosecutors, and nationally recognized

experts that are in my Zone 7. The group of professionals that I've called on

the Apple Podcast app or wherever you listen to your favorite podcast.
