In April 1991 recur in works. Police arrested 40 people, including Walter is Bulacio, who after spending hours locked in a dungeon and 5 days in a coma, died in the midst of contradictory statements. The cover is changed from "grave injury death" a "suspicious death", but the culprits do not appear, despite rallies of repudiation. Since then, a new little song is taken up by the public: "I knew, I knew, police Bulacio killed him."
