LEWISTON, Idaho (AP) — The U.S. Coast Guard has joined the search of the Snake River near Clarkston, Wash., for the body of a Lewiston woman who has been missing since April 2010. Asotin County (Wash.)

Sheriff Ken Brancroft tells KLEW-TV that a fisherman pulled up an anchor and something wrapped in a tarp came up with it before breaking free. Bancroft says that information helped narrow the search for the body of Rachael Anderson. Anderson's estranged husband, Charles Capone, faces trial on a first-degree murder charge in March.

Capone's co-defendant, David Stone, has pleaded guilty to failing to notify law enforcement about Anderson's death. Information obtained during plea negotiations led to November searches of the river west of Clarkston. Officials say the current search will continue through today, if necessary.
