>> tied to the death of a u.s. citizen in libya.
>> this is sad and the investigation continues. the u.s. is calling on libya to thoroughly investigate the killing of an american teacher in benghazi. he was shot to death while jogging. he caught chemistry at benghazi's international school and planned to return home to texas to his wife and young son for christmas. smith was the heart of the school. his death came days after they called on lybians to attack u.s. interests everywhere.
