The operation involved the disappearance of political dissidents. At least 119 people are alleged to have been abducted and later killed by state forces in the secret operation. The DINA claimed the murders were the result of inside-fights, and supported the creation two false magazines in Brazil and Argentina to support this claim. The magazines published a list of 119 dead political opponents. One of these fake magazines, titled LEA, was published by Codex Editorial, a dependent of the Argentine Ministry of Welfare, directed by José López Rega, counsellor of Isabel Perón and founder of the Triple A death squad.
