Camp No Camp No ( also known as Camp Seven ) is an alleged secret detention and interrogation facility ( black site ) related to the United States detainment camps located in Guantánamo Bay , Cuba . On January 18 , 2010 , Scott Horton asserted in an article in " Harper ' s magazine , " the result of a joint investigation with NBC News , that such a facility was maintained outside the regular boundaries of the Guantanamo Bay detention camp s . Description . Estimated to be located about a mile beyond the regular camp boundaries , the camp was described as a highly secret facility referred to as " Camp No " by Guantanamo guards . When soldiers asked about it , they were told " No , it doesn ' t exist " . The compound looked like other camps except that it was surrounded by concertina wire and had no guard towers . The guards who told Horton about it said that it looked as if it could hold eighty prisoners . Some areas looked like the interrogation centers in other parts of the main camp . They had seen non - uniformed personnel going to that area and speculated they were CIA . They suggest that the camp was used for secret interrogations , including the use of illegal interrogation techniques , such as waterboarding , commonly classified as torture . In an account published in " Harper ' s " , guards attested they had seen three prisoners taken individually in the direction of Camp No by the vehicle they called the paddy wagon the night of June 9 . The paddy wagon contained a cage large enough to hold one prisoner at a time . All three had been taken there by 8 pm . Homicides related to Camp No . Horton asserts that , according to interviews he conducted with four former camp guards , Army Staff Sergeant Joseph Hickman and three men who served under him , the three detainees reported by the military on June 10 , 2006 as having committed suicide instead likely died while at Camp No , or soon after , as a result of secret interrogations under torture . DOD had announced that the three men had died in their cellblock by hanging themselves in their cells . The Naval Criminal Investigative Service ( NCIS ) released a heavily redacted report in August 2008 ; it said that the three men ' s hangings had gone undetected for two hours . The detainees were Salah Ahmed Al - Salami , Mani al - Utaybi , and Yasser al - Zahrani . Horton wrote that DOD carried out a cover - up in asserting that the deaths were the result of suicides , all carried out the same night . He said the guards reported having seen a van , used only for the transport of individual prisoners , return that night from the direction of Camp No and go directly to the medical center , where something was unloaded . There was soon much crisis - related activity . This was before 11 : 45 pm , more than an hour before the first bodies of the " suicides " were reportedly discovered in the cellblock . In addition , sergeant Hickman , whose position in a tower gave him an overview of the cell block , said that he saw no prisoners being taken from the cellblock to the medical clinic that night . In February 2010 , Brent Mickum , the lawyer for Shaker Aamer , a detainee who is a British resident , said his client had described suffering torture at a separate location outside the regular camp on June 9 , 2006 when the other detainees died . He was subjected to what has been called dryboarding , which led to temporary asphyxiation . Mickum said that , from Aamer ' s description , he thought it " ' likely ' Mr Aamer ' s torture was in the same ' black site ' area , Camp No , identified by the Harper ' s article . " Although Aamer was cleared for release in 2009 , he is still being held at Guantanamo , for undisclosed reasons .
