Fire damaged an apartment at the complex on 2402 West 10th Street in The Dalles on Sunday.  According to Mid-Columbia Fire and Rescue Division Chief Dan Hammel, firefighters who responded found a fire in the exterior wall of the unit, which was contained to the immediate area within the wall, but the interior of the unit was damaged by water and firefighting operations to access the wall space.  The cause of the fire has been determined to be a result of an electrical failure within the wall wiring.  As a result of the damage to the electrical wiring, the power to all six units in the building had to be disconnected and resulted in the displacement of those occupants.  The American Red Cross was contacted to assist with the needs of those individuals.
