MOSCOW, Idaho -

Prosecutors in northern Idaho won't be able to present evidence from an experiment intended to show their theory about how a Washington state woman's body was dumped in the Snake River by her estranged husband.

The Lewiston Tribune reports that 2nd District Judge Michael J. Griffin on Monday denied the request from the Latah County Prosecutor's Office.

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

Authorities say she was lured to a Moscow, Idaho, auto repair shop owned by 52-year-old Charles A. Capone, where she was drugged and killed. Her body hasn't been found.

Capone is charged with first-degree murder.

Griffin says the river has likely changed in the last four years.
