JACKSON, MO (KFVS) -

There are new details Friday night on a case that's now considered closed. Heartland News got a rare and exclusive look inside the Waller case files.

Lt. David James of the Cape Girardeau County Sheriff's Office and Jackson Police Chief James Humphreys gave a glimpse into their lives over the past two years.

They used technology and good old-fashioned police work to build a case against Clay Waller.

"We knew right away that he was the prime number one suspect," said Lt. David James.

Clay Waller was set to stand trial in September.

Even without a body, investigators felt good about the evidence.

"I felt confident we could get a conviction we had a strong case," said James.

As for the key pieces of evidence, both officers point to video that shows Clay Waller hosing out and using 409 to clean a boat the night after Jacque disappeared.

"The way he was washing the boat and spending so much time on the center of the boat would have been powerful to a jury," said James.

It's a boat Waller admitted to launching in the Mississippi River to take Jacque Waller's body, which was in a trash can, to a beach area near Devil's Island in southern Illinois.

There was another big piece of evidence.

"The bloody carpet that was found that was hidden and concealed," said James.

It was concealed in a basement crawl space where Clay Waller was living in Jackson.

It was taken from the hallway where he admitted to beating and then strangling Jacque.

"The case just got better with time, like a fine wine or whiskey it got better with time," said James.

Investigators believe that Clay Waller got nervous.

"That pressure was always there, he knew it wasn't going away," said James Humphreys-Jackson Police Chief.

Finally, there was a confession.

Heartland News obtained a new picture of Clay Waller wearing his jail uniform leading investigators to where he buried his wife in the Devil's Island area.

He wasn't even sure exactly where the spot was.

Authorities had about a 50-yard area to search.

However, they had a clue; Clay said he poured a bag of fertilizer on top of Jacque.

"There were trees near her grave and one nearest to her grave was dead, burned up by something," said Lt. James. "It was likely the fertilizer."

One investigator keyed in on that and sure enough, Jacque's grave was there right under a pile of debris.

"I remember taking a minute and saying thank God, thank you," said Humphreys.

"Everyone paused for a long moment of silence and said a prayer," said James. "She was treated with dignity and respect when she was taken out of her temporary grave."

And there is the likely last known video of Jacque Waller getting money out of an ATM in Cape. Police say she gave that money to Clay Waller.

Then there's a picture of Jacque and Clay together at a Cape Girardeau pharmacy. She was buying his prescription just a few hours before he killed her.

Authorities say Clay tricked Jacque and premeditated the whole thing.

It's perhaps the biggest case to hit Cape Girardeau County, and one these officers will never forget.

"It's the biggest case of my career," said Humphreys.

Both officers say there would never be enough news time to thank everyone who contributed to the Waller case.
