From A&E, this is Cold Case Files, the podcast. On April 9, 9th, 1993, Robert Spangler and his wife Donna set out on the Page Spring Trail for a backcountry trip. Two days later Mr. Spangler hikes out alone.

He makes his way to the Park's backcountry office and tells National Park Rangers of a tragedy on the trail.

This is Ranger Ken Phillips of the National Park Service.

As they were hiking out of the canyon toward Horseshoe Mesa,

they had stopped so that Bob could set up a camera and take a picture.

This is Special Agent Bev Perry.

And while he was making some adjustment with the camera and was not looking at her that he heard a slight noise and

turned around and she was no longer there.

According to Spangler he peered over the red-walled cliffs and saw his wife's body 140 feet below.

Spangler says he climbed down to Donna and found her dead.

Park Rangers are dispatched to the scene and retrieved Donna Spangler's body.

The investigation is then turned over to the Coconino County Sheriff's Office.

Deputy Brett Ry meets with the victim's husband.

He was very upset. I mean he would break down cray. Grant Rye meets with the victim's husband.

He was very upset.

I mean, he would break down crying.

Then he would talk a little bit,

and he would break down crying some more.

And he spoke very tenderly towards Donna.

I remember him stating that he took a cloth and wiped her face off

and sat there with her for a while

and eventually hiked out to get the authorities.
