The murder of Mary Kay Hesse has been on the minds of the people of Wahoo, Nebraska, for 56 years now.

I remember being about nine years old, out in the front yard.

My mom came out and said, hey, get in this house right now.

A girl in Wahoo has been murdered.

And I remember that plain as day.

It didn't happen that often in Nebraska.

Murders were rare.

Mary Kay Hesse was a 17-year-old high school student from Wahoo, Nebraska, who was killed by stabbing in 1969.

The Mary Kay Hesse case is unique because of how many people have tried to solve it, and they just hit brick walls right and left.

I'm Bob Frank.

Back in 1999, I was a sergeant in charge of the Nebraska State Patrol Cold Case Unit.

She was running.

You could see the struggle.

The blood on the ground and the footprint showed there was a struggle in this area.

Her shoe and another spot of blood was found, and then her body.

I'm hoping the integrity of the evidence is still there as far as it's not too old to test, as far as DNA.

We're hoping after 30 years we can pull a fingerprint off those books.

The purse was found at the crime scene.

This stuff has been in here for the last 30 years.
