And how had she died?

Investigators photographed the scene, measured and made a cast of that shoe print, and sent Mary Kay's body for an autopsy.

It was determined that Mary Kay had been beaten and was stabbed to death, leaving 14 wounds.

No knife was found at the scene.

Stabbing somebody 14 times, though, what did that tell you about the nature of the crime?

Was she sexually assaulted?

The investigation was initially handled by various law enforcement departments.

Mary Kay's clothing was sent to the FBI to J. Edgar Hoover's attention before the days of DNA testing to see if anything could be learned.

Investigators questioned people around town about the day of the murder.

A witness reported seeing Mary Kay that day at around 5 p.m., getting into a car that had two men at that street corner.

In those early days and weeks, did you think, oh, they're going to find whoever did this?

Oh, yeah.

Mark Miller and Kathy Toll are Mary Kay's cousins.

These are some of Mary Kay's personal belongings, right?

This is her 4-H.

Is she proud of what she did at the 4-H?

Look how tiny she was.

Kathy was nine and Mark eight when they learned Mary Kay had been murdered.

Kathy recalls being picked up early from school the day Mary Kay's body was found.

Kathy's family drove to her cousin's home.
