But these radars work like a submarine sonar.

It sends down waves, it bounce back and it reveals images.

And the FBI was there first with their experts.

Investigators knew the body was under a bedroom based on what David Wiley had told them.

So the FBI focused on one of the two bedrooms there.

But after three days of searching, the equipment had to be pulled out and they hadn't yet found anything significant.

That's where this case takes a fascinating turn because that's where a man named Tim Miller comes in.

After his own daughter was abducted and murdered, he formed a nonprofit called Texas EquiSearch.

He has since found so many missing people through his company.

It's a true labor of love what he does, honoring his daughter Laura's memory.

And Miller believes his daughter, just as a quick aside, was killed by a man named Clyde Edwin Hedrick, the longtime suspect in the Texas Killing Fields case.

And 48 Hours covered this case.

And in 1984, 16-year-old Laura Miller was found in the same field, not far from where another victim had been found.

Hedrick wasn't charged or sentenced in connection to her death and recently died in March 2026.

Well, so Tim Miller looked in the other bedroom that had not yet been checked.

And that's where his team found the location of Kim's body in a matter of minutes.

And it's not in the show, but I interviewed the ground penetrating radar operator who showed me how it worked.

He put the machine down.

It senses a disturbance, what they call in the space under the floor.

And then Tim knocks and hears that it has a hollow sound.
