Investigation
An extensive two-year enquiry was held on the events in 1908, initially presided over by judge Alves Ferreira and later by José da Silva Monteiro and Almeida de Azevedo. During this period, evidence was provided to indict members of the Carbonária who were intent on weakening the monarchy. The investigation was concluded on 5 October, and the trial was scheduled to begin on 25 October. In the meantime, new suspects were discovered: Alberto Costa, Aquilino Ribeiro, Virgílio de Sá, Domingos Fernandes and others who were in refuge in Brazil or France; two were killed by the Carbonária to silence them.
The process was in vain; after the proclamation of the Portuguese Republic, judges Juiz Almeida and Azevedo delivered their report to José Barbosa (their superior). He in turn sent it to Afonso Costa (Minister of Justice for the Provisional Government), by whom it was lost. It is known that the exiled King Manuel II received a copy of the report from the judges, but these were stolen from his residence during a robbery shortly before his death in 1932.
