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

Now this ain't just any old podcast, honey.

As a crime scene investigator with over 40 years' experience in the criminal justice system,

I started my career in the trenches, and honey, I've stayed there.

So I've worked every facet of the criminal justice system, police, courts, and corrections.

I've worked with law enforcement and victims of crime and criminals to solve cold cases,

and I have genuinely befriended them all.

Well, not all of them, but most of them.

As a work in CSI, I'm not a first responder.

I'm a last responder.

I'm going to be bringing you into the depths of these cases with me.

We're going to talk to family members.

Tammy was the girliest of the three of us.

Tammy was the dancer. She was, you know,

tiny and petite and just cute. And she had great tone. And she just excelled. Everything she did and dance. That was her thing. She loved it. And she had a ton of friends.

She did. The thing about me and Tammy that was very different is I was always very, I had a lot of

common sense. I had a lot of street smart. Tammy wasn't. Tammy was very spontaneous. Tammy was very in the moment.

And it's like, this is great. This feels good. Let's just do this. I'm not going to think about what happens next.

Detectives and prosecutors on these cases. She was stabbed at least 130 times.

And at some point in time of our right now.

We know that.

There was probably other things at place.
