<p>U.S. officials gave instructions for Benghazi Medical Center to use a "John Doe" pseudonym on the death certificate of Ambassador Christopher Stevens after he died of asphyxiation in the Sept. 11, 2012 terrorist attacks on the U.S. mission in Benghazi, Libya. That's according to a U.S. official speaking on condition of anonymity because the official isn't authorized to speak publicly on the matter. The reason for the pseudonym, says the official, was to avoid drawing undue attention to the importance of the victim as Americans rushed to figure out how to recover Stevens' body and return it to the U.S.</p>
