Between 1975 and 1979, thirty-one unidentified bodies bearing marks of torture appeared at various locations along Uruguays coastline. These bodies were material proof of the death flights implemented in neighbouring Argentina after the military coup. In Uruguay, in a general context of political crisis, the appearance of these anonymous cadavers first generated local terror and was then rapidly transformed into a traumatic event at the national level. This article focuses on the various reports established by Uruguayan police and mortuary services. It aims to show how,the administrative and funeral treatments given at that time to the dead bodies, buried anonymously (under the NN label) in local cemeteries, make visible some of the multiple complicities between the Uruguayan and Argentinean dictatorships in the broader framework of the Condor Plan. The repressive strategy implemented in Argentina through torture and forced disappearance was indeed echoed by the bureaucratic repressive strategy implemented in Uruguay through incomplete and false reports, aiming to make the NN disappear once again.
