Jacque Waller: She Thought She Had Left Him Behind. He Had Already Dug Her Grave.

A divorce meeting, a trip back to his house, and a plan that had already been set in motion.

Portrait of Jacque Waller, the Missouri mother of three whose 2011 disappearance led investigators to uncover a planned killing.

A Marriage Coming Apart

By the spring of 2011, Jacque Sue Waller and her estranged husband, James “Clay” Waller, were in the middle of a divorce. They had separated in March. Jacque had been staying with family in Ste. Genevieve County, Missouri, while the couple’s five-year-old triplets remained tied to the custody dispute unfolding back in southeast Missouri.

On June 1, 2011, Jacque returned to Cape Girardeau for a meeting with Clay and her attorney about the divorce. After that meeting, she went to Clay’s home in Jackson, Missouri. It was the last day she was seen alive.

The Story He Told

After Jacque vanished, Clay told investigators that the two had argued and that she left his house on foot around 4 p.m. He later claimed he returned home and found her blue Honda Pilot gone. The vehicle was eventually found abandoned along Interstate 55 with a flat tire.

But almost immediately, suspicion settled on him.

Jacque’s family said she had been afraid of Clay. In the federal case that came years later, prosecutors said he had threatened her repeatedly during the breakup and told her that if she divorced him, she would be “signing her death warrant.”

The Grave on Devil’s Island: Jacque Waller

What made the case even more disturbing was how deliberate it was.

According to federal prosecutors, Clay crossed from Illinois into Missouri on June 1, 2011, with the intent to kill Jacque. The day before, he had already dug a grave on the Illinois side of the Mississippi River near a place known as Devil’s Island.

When Jacque came to his home after the divorce meeting, prosecutors said he killed her there. In his later state plea, he admitted beating and choking her. Afterward, authorities said he transported her body by boat across the river and buried her in the grave he had prepared in advance.

Nearly Two Years Without Answers

For Jacque’s family, the case turned into a long search with no body and no certainty.

She remained missing for nearly two years. Then, in 2013, Clay entered a plea deal in Cape Girardeau County. In exchange for pleading guilty, he agreed to lead authorities to Jacque’s remains and describe what he had done. Her body was found near Devil’s Island on the Illinois side of the river.

He pleaded guilty to second-degree murder and received a 20-year sentence in Missouri. During the plea proceedings, local reporting said he admitted striking Jacque in the face and head and pressing his forearm against her throat.

Why He Took the Deal

At the time of the plea, Jacque’s body still had not been found. That mattered. Even when investigators strongly believe they know what happened, no-body murder cases can be harder to prove at trial. In court, the judge acknowledged that prosecutors could not guarantee a conviction without recovering her remains. In exchange for pleading guilty, Clay Waller agreed to lead authorities to Jacque’s body and explain how he killed her. The deal spared him the risk of a possible life sentence in state court while giving Jacque’s family what they had been denied for nearly two years: answers, a confession, and the chance to bring her home.

The Federal Case

The state case did not end everything.

In 2017, Clay Waller pleaded guilty in federal court to interstate domestic violence tied to Jacque’s murder. Federal prosecutors said he traveled across state lines with the intent to kill her. The plea called for a 35-year federal sentence, running concurrently with the earlier state sentence.

He had also previously been sentenced in a separate federal case for sending an online threat to Jacque’s sister, Cheryl Brenneke, after Jacque disappeared.

What Stayed With People

Jacque Waller’s case stayed with people because of how carefully it was planned.

This was not a sudden fight that spiraled out of control, according to prosecutors. They said the grave was dug first. The divorce meeting still happened. Then Jacque went back to the house, believing she was dealing with another step in the separation.

Instead, investigators said, Clay had already decided how it would end.
