Missouri Man Who Killed Wife Gets 35 Year Federal Sentence

A federal judge has extended the prison sentence of a southeast Missouri man who killed the mother of his triplets amid a divorce and then helped write a tell-all book.

Forty-seven-year-old James Clay Waller, of Jackson, was sentenced Tuesday to 35 years for interstate domestic violence.

Waller admitted through his plea to digging a grave for Jacque Sue Waller in 2011 on an island on the Illinois side of the Mississippi River. He also admitted to beating and strangling her the next day after a meeting at a divorce lawyer's office. The triplets were 5 at the time.

In exchange for leading investigators to her body in 2013, Waller previously was sentenced to 20 years in state prison for second-degree murder. The state and federal sentences will run concurrently.
