In January 2005, Michael Townley, who now lives in the U.S. under the witness protection program, acknowledged links between Chile, DINA, and the detention and torture center Colonia Dignidad. The center was established in 1961 by Paul Schäfer, who was arrested in March 2005 in Buenos Aires and convicted on charges of child rape. Townley informed Interpol about Colonia Dignidad and the Army's Bacteriological Warfare Laboratory. This last laboratory would have replaced the old DINA laboratory on Via Naranja de lo Curro street, where Townley worked with the chemical assassin Eugenio Berríos. The toxin that allegedly killed Christian-Democrat Eduardo Frei Montalva may have been made in this new lab in Colonia Dignidad, according to the judge investigating the case. In 2013, a Brazilian-Uruguayan-Argentinian collaborative documentary, "Dossiê Jango", implicated the same lab in the alleged poisoning of João Goulart, Brazil's deposed president.
