These days, we're all a little skeptical of pretty much every politician, right? But it wasn't always that way.

Sure, there were disagreements about policy and ideology back in the day. But when the vast majority of

people trusted a president, it was to a degree we, sadly, just can't comprehend. With that in mind,

got to add another chapter to the story of Abraham

Lincoln's assassination. There was a sense among his cabinet members that the people should have

one last chance to connect with their martyred president. Thus began a train trip through hundreds

of towns with stops in 13 cities where people got to look at Lincoln in his open coffin as his body began

to decompose. I'm Patty Steele, the funeral train seen in person by fully one-third of all Americans.

That's next on the backstory.

There's a type of soil in Mississippi called Yazoo Clay.

It's thick, burnt orange, and it's got a reputation.

It's terrible, terrible dirt.

Yazoo clay eats everything, so things that get buried there tend to stay buried.

Until they're not.

In 2012, construction crews at Mississippi's biggest hospital made a shocking discovery.

Seven thousand bodies out there or more.

All former patients of the old state asylum, and nobody knew they were there.

It was my family's mystery.

But in this corner of the South, it's not just the soil that keeps secrets.

Nobody talks about it. Nobody has any information.

When you peel back the layers of Mississippi's Yazoo Clay, nothing's ever as simple as you think. The story is much more complicated and nuanced than that.
