The husband of a missing mother of triplets is scheduled to appear in court in southeast Missouri on charges unrelated to his wife's disappearance.

The Southeast Missourian reports that Clay Waller was arrested Friday and is scheduled to be arraigned on stealing and harassment charges Monday afternoon. Police said the charges had nothing to do with the disappearance nearly two months ago of Waller's wife, Jacque Sue Waller, the mother of 5-year-old triplets.

Clay Waller is considered a "person of interest" in the disappearance but denies involvement and no charges have been filed in that case.

Waller's lawyer, Scott Reynolds accused police of arresting Waller so they could question him about Jacque Waller. Police, however, said they couldn't discuss the nature of the questioning.

Reynolds said Waller would plead not guilty to the stealing and harassment charges.

Clay Waller is said to have told investigators that his wife walked away from his home in Jackson, Mo., on June 1 after the two quarreled following a divorce hearing that same day. 

Authorities said Jacque Waller drove to her estranged husband's home at around 4:00 p.m. June 1 to pick up her son, Maddox.

But the child was not at the home when Waller arrived, and family members say they think Clay Waller, a former police officer, lured her to the home to kill her.

Police found the missing woman's car on June 2 abandoned along a Missouri highway. Her purse, keys and cell phone were missing from the vehicle. 

Waller's Blue Cross Blue Shield business cards were also found along another state highway about eight miles from where her car was recovered. Waller worked as a manager for the health insurance company.

Anyone with information on Jacque Sue Waller is urged to call the Jackson Police Department at 573-243-3151.
