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

We are going to solve these cases on air together.

Listen to Zone 7 on the I Heart Radio app, the Apple Podcast app, or wherever you listen to

your favorite podcast.
