Hi, frontline listeners. I'm Rainy Aronson, executive producer of Frontline.

Today we're sharing episode one of our new investigative podcast series, Unresolved.

It's the story of a federal initiative to investigate over 150 unsolved killings from the civil rights era.

We ask what prompted the government to try to write the wrongs of the past,

and we investigate what justice looks like for the families of the victims.

Across five episodes, Host and reporter James Edwards looks into a few of these cases.

He speaks with families whose loved ones were killed and reflects on his own family's story.

I hope you enjoy episode one of Unresolved.

The following podcast contains subject matter and descriptions of violence.

Some listeners may find disturbing.

6427 South St. Lawrence Avenue.

I grew up less than four miles from this address on the south side of Chicago.

It's a typical home you'd find in many parts of the city, a red brick two-story building,

or as a locals call it, a two-flat.

There was once a boy, a black boy, who spent his childhood here.

I went past it not long ago when I still lived in Chicago.

Some colleagues and I were interviewing a policeman about what it was like to be a black officer in the city.

We were in his car and the house was one of our last stops that day.

Before we head back, I wanted to go to this house,

where this house was the start of a civil rights movement.

That's Emmett Till's house.

Really?
