But U.S. Ambassador in Bishkek Marie Yovanovitch said today that the serviceman, Zachary Hatfield, remains under investigation in connection with the incident.
Hatfield shot airport employee Aleksandr Ivanov as he approached a U.S. facility at Kyrgyzstan's Manas Airport in December.
A Kyrgyz inquiry reportedly concluded that Hatfield committed a crime.
U.S. officials have said Hatfield shot Ivanov in self-defense after he saw him with a knife in his hand near a section of the airport reserved for U.S. and coalition personnel.
U.S. service personnel at the base possess diplomatic immunity on the basis of a bilateral agreement.
