There's a town in Mississippi called Greenville.

It's in the heart of the Mississippi Delta, and more than 85% of the homicides that happen

here are unsolved.

So many of the people who commit these murders aren't in jail.

They're in a car driving past your house.

You probably stroll by them in the supermarket or see them pumping gas.

That also means the families of these victims have learned to live with not knowing.

One of those unsolved murders happened almost 20 years ago.

She was a grandmother, a major influence in Greenville and a bit eccentric.

Beloved by her family, maybe even the whole town.

She drove an old Ford with a life-size paper mache man in her backseat.

She was a big Democrat who hosted governors and organized dozens of charities.

Didn't seem like anybody had a bad thing to say about her.

Then she was murdered, and nobody ever solved it.

You get the feeling that it never will be, that it's been so long it doesn't matter.

Well, it matters to me.

Because that town, Greenville, Mississippi, is where I grew up.

And that family is my family.

And it was my grandmother who was found murdered in her son's room.

And I want some answers.

This is a story about what happens when you don't know.
