You've probably seen these.

Photos of missing children printed on milk cartons,

pages of the newspaper,

posted on storefronts, or even on tax forms.

For the most part, I ignore them.

I'm sure you're so used to them that they've become a part of the design.

Sometimes you might actually read them,

but you may assume that teens are runaways,

and the children were kidnapped by one parent following a bitter separation.

Either way, you probably go on with your day and forget about them.

Except one person, a man named Thomas Heimer,

an inmate in Florida.

Heimer gave a lot of thought to the picture of a list of children.

A missing girl that he saw printed on the pages of USA Today.

In 2006, Heimer reached out to Detective and said,

I know that girl.

I killed her.

I'm going to make you famous.

This is how the investigation into a list of attorneys' disappearance

was given a boost six years after she had first been reported missing.

This confession turned out to be false,

but it provided a major break in the case nonetheless.
