Murphy Pepper, a seventh grader at Francis C. Hammond Junior High School, overcame his final opponent in a recent Alexandria spelling bee by correctly spelling "tsetse," the African fly that causes sleeping sickness. He went on to victory in the city-wide competition by spelling "vulpine" (like a fox). Pepper competed in the spelling bee, sponsored by the Journal Newspapers, with students in grades 5 through 8 from nine elementary schools and two junior high schools. Karen Loew of Fairfax won the regional bee last Sunday.
