Chenowith Elementary School, the Wahtonka Campus, and North Wasco County School District 21’s administrative office was placed in lockdown Tuesday after a man was reported with a gun on Chenowith Road near the entry to Foley Lakes Mobile Home Park.  In a joint statement, Wasco County Sheriff Lane Magill and D-21 Superintendent Candy Armstrong said the man was located when officers arrived in the area, and during the incident he showed behavior indicating he wanted only to cause harm to himself.  The man was taken to Mid-Columbia Medical Center for a mental evaluation with Mid-Columbia Center for Living, the weapon was located and secured, and the lockdown was lifted.  The investigation by law enforcement found the incident was isolated in nature, and no school children or staff were in danger.
