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

We are going to solve these cases own air together. Listen to Zone 7 on the I Heart Radio app,

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