DINA existed until 1977, after which it was renamed the Centro Nacional de Informaciones (CNI) (National Information Center).
" The CIA actively supported the junta after the overthrow of Salvador Allende. The head of DINA, General Manuel Contreras, was made a paid asset despite continuing CIA reservations concerning the human rights abuses of the organization. Eventually the CIA became aware of DINA's "possible" involvement in the assassination of Orlando Letelier and Ronni Moffitt in Washington D.C., but they continued to maintain him as an asset. The CIA reports remain heavily excised.
In July 1976, two magazines in Argentina and Brazil published the names of 119 Chilean leftist opponents, claiming they had been killed in internal disputes unrelated to the Pinochet regime. Those two magazines would disappear after this one and only issue. Judge Juan Guzmán Tapia would eventually ask Chilean justices to lift Pinochet's immunity in this case, called "Operation Colombo", having accumulated evidence that he had ordered the DINA to plant this disinformation, in order to cover up the "disappearance" and murder by the Chilean secret police of those 119 persons. On September 2005, Chile's Supreme Court would accept the lifting of Pinochet's immunity on this case. Judge Victor Montiglio, who took over the case after Juan Guzmán Tapia's retirement a few months before, has yet to name the doctors who would statue on Pinochet's health and ability to be interrogated. Victor Montiglio is known as a Pinochetist, and supports military auto-amnesty laws. He has already accorded amnesty to Manuel Contreras, who was given firm prison sentence in 2004 in the Operation Colombo trial.
Michael Townley described numerous meetings between Pinochet and Italian terrorists and spies as well as Pinochet's meetings with anti-Castro Cubans 
Michael Townley worked with Eugenio Berríos on producing sarin gas in the 1970s, in a house DINA had in the district of Lo Curro, Santiago de Chile. Eugenio Berríos , who was murdered in 1995, was also linked with drug traffickers and agents of DEA
Investigations by Amnesty International and the Chilean National Commission for Truth and Reconciliation Report have verified that Colonia Dignidad, long held for a center used for delusions of ex-Nazi Paul Schäfer, was used by DINA as a concentration camp for the detention and torture of political prisoners. Most accounts have this happening between 1973 and 1977 but precise dates are not known. Boris Weisfeiler, in particular, is thought to have disappeared near Colonia Dignidad.
The son of DINA head Manuel Contreras claims that his father and Pinochet visited Colonia Dignidad in 1974, and that his father and Schäfer were good friends. The current leader of Villa Baviera admits that torture took place within the old colony, but claims that Villa Baviera is a new entity.
In March 2005, former DINA agent Michael Townley acknowledged links between Colonia Dignidad and DINA, as well as relations with the Bacteriological War Army Laboratory. He would have spoken about biological experiments imposed to detainees, with the help of the fore-mentioned laboratory and another one, that used to be situated on Via Naranja de lo Curro Street. According to Townley, former Christian Democrat President Eduardo Frei Montalva was assassinated by a poison made at Colonia Dignidad.
On an undated letter to Augusto Pinochet, CIA and DINA agent Michael Townley advised him that Virgilio Paz Romero, an anti-Castro Cuban, was taking photographs of British prisons in Northern Ireland in 1975 as a DINA assignment. The photographs were to be used by the Chilean government at the United Nations in New York to discredit the United Kingdom and accuse them of human rights violations. But they arrived too late to be used, and were finally published in El Mercurio.
