I'm Cheryl McCollum, host of the brand new co-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

to help me work hundreds of cases you've heard of and thousands you haven't.

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.

This is a special episode of Crime Stories with Nancy Grace,

Finding Chase Masner, Episode 1.

Chimacir Sanjum.

Chase Masner is an Iraq war veteran, a husband, a father, and he's missing.

His mother Stephanie has worried about him every day for three years.

As wife told us, she dropped him off at a quick trip in Cobb County where he works.

As family says, he was last seen at a friend's house in Kennis Hall three years ago on March 27th.

We don't know what happened. I mean, it's like he vanished from that home, not to be seen or heard

from again. This is a hint. He would never do this. He wouldn't just go and leave his family and

his loved ones here. Despite some intense searching, few clues have been found.

We have a missing veteran. We have a friend, a son, a father, and our main goal has always been

to bring him home and that emotion will never end until he's brought back home.

Three years after her son Chase Masner were missing, Stephanie could continue searching for him.

I've lived the last three years, not knowing.

In every single day.

It's just hell.
