PEMISCOT COUNTY, Mo. - Clay Waller may still be a person of interest in his wife's disappearance, but he's no longer in southeast Missouri.

The U.S. Marshals Service tells Local 6 that Waller has been moved from Pemiscot County. He's been transfered to a federal facility in what the Marshals Service says is an undisclosed location to serve a five year sentence on federal internet threat charges.

Waller pleaded guilty back in October to threatening his sister-in-law on the website Topix. In addition to the prison time, Waller will receive three years of supervision after his release.

Waller is also considered a suspect by prosecutors in his wife's June 1, 2011 disappearance. From day one, Jacque Waller's parents have said Clay Waller killed their daughter, because he was threatening to do so for quite some time.
