Jacque Sue Waller a 39-year-old mother of triplets, was last seen June 1, 2011. Her husband, James "Clay" Waller, was charged with first-degree murder and will stand trial in the fall.

His father died in December 2011, the report said.

The Cape Girardeau County prosecutor's office issued a one-paragraph statement Thursday. It said police recovered a body on Wednesday that has been confirmed as Waller.

She was 39 when she disappeared on June 1, 2011. No information was released on where the body was found. A woman answering phones at the prosecutor's office said no further comment would be made, citing an ongoing investigation.
