l outrage and led Congress to expel lawmaker Sergio Naya, owner of the construction empire which built the apartment block. The report found the disaster was caused by "generalized errors" in the construction of the building and "very serious errors in the pillars," Globo said. A videotape broadcast on television shortly after the collapse showed Naya bragging about forging official documents and using low-grade building material in his construction projects that were later passed off as quality materials. "I can't say whether or not (the material) was first-rate or second-rate," investigator Jose Afonso Garcia told Globo. "What I can say is that the material used was within the norms specified by the Brazilian Association of Technical Norms." Victims of the collapse, who return daily to the site of the building to pick for personal possessions in the rubble, said they were not satisfied with the outcome of the public inquiry and they planned to launch a private investigation. Naya's construction company has stopped paying compensation to victims because its assets have been frozen by a court. "A building falls on our heads, we're completely without defense and on top of that an inquiry says the material was first rate?" resident Rauliete Barbosa Guedes told Globo.
