An American soldier visiting a girlfriend in Russia's port city of Vladivostok was arrested on charges of stealing from her and remains in custody, according to several U.S. officials. U.S. officials said Monday the soldier, Staff Sgt. Gordon Black, 34, was stationed in South Korea and was in the process of returning home to Fort Cavazos in Texas. Instead, officials said that Black, who is married, traveled to Russia to see a longtime girlfriend.
