MOSCOW, Idaho (AP) — A northern Idaho man accused of strangling his estranged wife and dumping her body into the Snake River has opted not to testify in his own defense.

The Lewiston Tribune reports that 53-year-old Charles Capone of Moscow on Monday declined to take the stand in his first-degree murder trial in 2nd District Court. Closing arguments are scheduled for Tuesday and then the case will go to the jury. Capone is accused of killing 40-year-old Rachael Anderson from Clarkston, Washington, in April 2010.

The body of the mother of four hasn't been found. A co-defendant last week testified that he witnessed Capone kill Anderson and then helped dispose of the body in the Snake River.
