Rousseff and Galeno then began sleeping each night in a different location, since their apartment had been visited by one of those arrested. They returned home secretly to destroy documents so when in March 1969, the police searched the apartment, no documents were found. They stayed in Belo Horizonte a few more weeks trying to reorganize Colina, but had to avoid their parents' houses, since these were watched by the military. (Rousseff's family had no knowledge of her participation in underground activities). In addition, Galeno had to undergo facial plastic surgery or a similar procedure (although he denies this) after a sketch of him was released for participating in a bank robbery. The organization ordered them to move to Rio de Janeiro since it was unsafe to remain. Rousseff was 21 and had just finished her fourth semester at the Universidade Federal de Minas Gerais School of Economics.
