Clarence and Marjorie Paulson (2 of Clubs, Minnesota)

[tense music] In December 1990, a Minnesota farmer named Eldon Wiese had picked up a home renovation project.

He bought a property in Maple Township about two years earlier, hoping to use it for ranching.

Now, the property was pretty remote, hours from any major city, and at the end of a dirt road that dead-ended at a field.

And the building that stood on it was, as detectives said at the time, in very poor condition.

I mean, before the sale, it was all but abandoned.

So over the years, Eldon and his son had been in the process of salvaging and removing boards from the dilapidated farmhouse.

But by 1990, they were ready to take the building off the block of its foundation, and that's when they found it.

I believe he described it first as it looked like a pair of cowboy boots, but then also some, some clothing is located.

So he ju- he gets down off this piece of equipment and takes a closer look, and he, he finds two bodies.

And so he immediately calls law enforcement.

That's Ryan Fischer, an investigator with the Cass County Sheriff's Office.

Been in law enforcement for 22 years.

I absolutely love being an investigator.

I love working, uh, complex crimes such as this one.

That day in 1990, December 15th to be exact, Eldon called the sheriff's office to report the bodies he'd found.

And believe it or not, it was Investigator Ryan Fischer's dad, Randy Fischer, who took the case.

So I'm actually, uh, third generation law enforcement, or third generation in my family to work for the Cass County Sheriff's Office.

Uh, so my dad was still an investigator at the time, and he actually worked on this case, um, quite a bit, actually.

So it was his dad's reports that Investigator Fischer reviewed before meeting with our reporting team.

In one, Investigator Randy Fischer took note of how the two decomposed bodies were both lying near the west edge of the foundation in fine dirt and debris.

You know, they're essentially mummified, if you will.

But they weren't exposed to the elements as such where they would've decomposed as, say, a body that was just left out in the woods, exposed to the elements.

Both were clothed, albeit in fraying clothes.

And even though the remains were mummified and would take three days to identify, everyone had a hunch about who this might be right away.

Rural America, right? You know, everybody's, you know, putting things together and that this is...
