Bomb threats bring in Dept. of Homeland Security
TRI-CITIES-- The Department of Homeland Security is now on the case of bomb threats being called into courthouses -- including the Benton County Justice Center.

Four-states have been the target.

Nearly 100 local government facilities in Washington, Oregon, Nebraska and Tennessee have had to evacuate buildings following the threats.

And the person -- or group -- behind the calls remains unknown.
