NEAR BAKER CITY, Ore. - The Oregon National Guard plans to add a helicopter to a search for a Sandy-area woman missing from a hunting trip with her husband in Eastern Oregon.
    
Doris Anderson, 76, went bow hunting last week near Baker City with her 75-year-old husband, Harold Anderson.

On Thursday, their truck and trailer reportedly got stuck deep in the forest.
    
Harold Anderson broke his wrist while trying to unload their ATV and free the stuck truck, according to his brother, Melvin Anderson.
   
The couple decided they needed help and started walking out of the forest when Doris Anderson started feeling weak.
    
While she walked back to the car, Harold Anderson hiked for more than 24 hours to get help.

Melvin Anderson said: "Harold was kind of confused and thought he had only walked two or three hours, but the sheriff said he had to have walked probably a day, and a night, and half a day to get out to the highway."

When police returned to the vehicle, Doris could not be found.
    
More than 40 people searched the area on Sunday.

Searchers hope to cover more area with the helicopter on Monday. The rugged area is one of the least-populated regions of Oregon.
