David Stone of Moscow pleaded guilty Wednesday to failure to notify law enforcement of the death of Rachael Anderson. Prosecutor William Thompson Jr. says Stone has agreed to testify about what happened after he arrived at the alleged crime scene.
Anderson's estranged husband, Charles Capone, faces trial for first-degree murder on March 31.

Thompson said detectives interviewed Stone twice last month and believe he was not responsible for Anderson's death, but helped cover it up.
Thompson says last month's search of the Snake River west of Clarkston, Wash., was related, in part, to what Stone told investigators.
