LEWISTON, Idaho -

The latest search of the Snake River for the body of a Washington state woman whose former husband is charged with killing her has come up empty.

The Lewiston Tribune reports the search that ended Saturday included the U.S. Coast Guard and officials from Washington state and Idaho.

Rachael Anderson, a 40-year-old mother of four from Clarkston, Washington, was in the process of getting a divorce when she disappeared April 16, 2010.

Authorities said 52-year-old Charles A. Capone lured her to a Moscow auto repair shop he owned, where he drugged and killed her.

Capone's attorney contends there's no evidence of Anderson's death in Idaho, leaving authorities with speculation and conjecture.

Capone has pleaded not guilty to first-degree murder. His trial is scheduled to start June 23.
