A southeast Missouri man has pleaded guilty to killing his estranged wife, a mother of triplets who was missing for almost two years before her body was found in Illinois last week.
Clay Waller of Jackson pleaded guilty Thursday to second-degree murder in the death of Jacque Waller. She had been missing since June 1, 2011, the same day the couple met with a divorce lawyer and argued over money.
Clay Waller was charged in his wife's death last year even though her body had not yet been found. He had faced a September trial in Cape Girardeau County Circuit Court.
Jacque Waller's sister, Cheryl Brenneke, has custody of their 7-year-old triplets. Clay Waller is serving a five-year term in federal prison for threatening Brenneke over the Internet.
