Marshall G. Cox, of Wallowa, was identified by the Wallowa County Sheriff's Office as the man brought to Sacred Heart with materials that prompted a massive emergency response on Wednesday, including diversion of patients from the hospital's emergency department. Security personnel at Sacred Heart reported the suspicious materials to police, who shut down roads and responded with an explosive disposal unit "out of an abundance of caution," said Julie Humphreys, a spokeswoman for the Spokane Police Department.
