A woman jogging along a deserted footpath in central Michigan disappeared.

When investigators find her body, clues at the scene point to a killer with professional training.

It took almost 20 years before an old hat and a chip of stainless steel no longer than a fingernail

brought the killer to justice.

On a beautiful summer day in 1986, Muriel Kirby started her day, as she always did, by meeting her daughter Jeanette for breakfast.

Well to me it was a very special routine, just talking over what had been going on and what was on her mind or my mind.

It was a very special, almost a friendship breakfast.

But this morning was different from the others.

Jeanette didn't show up and she never called or left a message.

Jeanette's employer said she hadn't shown up for work and she wasn't at her home either.

Her mother immediately notified police.

The 35-year-old divorcee with no children wasn't known for leaving town without notifying friends and family.

As night fell, the sky was dark with rain clouds and during the night, it was severe thunderstorms the worst in years.

I knew in my heart that Jeanette was somewhere in that storm and she needed help.

Jeanette was an avid walker and she often explored the secluded trails of nearby River Bend Park and undeveloped public space of more than 500 acres.

River Bend Park is very large. It's not what you would think of as a city park manicured and small in size.

The day after Jeanette disappeared, police found her car at the park.

A parking ticket indicated the car had been there since the day before.

A day-long search of the park turned up nothing. The search continued into the night.

I remember praying dear God, let her be alright.

I knew that it was wrong. Something was definitely wrong. Jeanette was too close to this family. She would never let us worry.

When Dawn broke the next day, police found Jeanette's body in an isolated ravine just a half mile from her car.
