Currently, he worked in the city's 1st Police District - a flagrant center that serves the central region of the city. According to the Public Ministry, a week before the operation that dismantled the plan to kill Gaeco promoter Amauri Silveira Filho, in August 2025, Maurício met with one of the suspects identified as responsible for carrying out the attack. In a statement, Maurício's defense informed that it is awaiting access to the records to analyze the "unnecessary request for temporary arrest of a public servant". Former Public Prosecutor's Office intern Gabriel Lira de Jesus, former MP intern arrested in operation against PCC infiltrators Reproduction/Instagram Another prisoner is law graduate Gabriel Lira de Jesus who, at the time of the facts investigated, was doing an internship in a criminal prosecutor's office of the Public Ministry in Campinas. His defense was not located. According to Gaeco, he would have used access to the institution's systems and databases to locate those being investigated with high economic power and demand money in exchange for supposed protection against investigations. The suspicion is that he entered the prosecutor's office with the intention of obtaining information for this type of practice. One of the findings of the investigation emerged after analyzing the cell phone of Maurício Silveira Zambaldi, known as "Dragão", suspected of financing the plan to kill prosecutor Amauri Silveira Filho. On Dragão's device, prosecutors found messages in which Gabriel Lira de Jesus demanded R$500,000 so that information about the businessman would not be sent to Gaeco. From these messages, investigators reached the then intern. According to the MP, he left the prosecutor's office a few weeks after operations that targeted "Dragon" and started working at a law firm in the Campinas region, which was also the target of searches this Tuesday. Former civil police officer Itamar Gomes da Silva is a former civil police officer who, according to the Public Ministry, helped the then intern and participated in the scheme. He was arrested in Cardoso (SP). Itamar would be responsible for connecting former investigator Maurício Aparecido de Oliveira to businessman José Ricardo, identified as one of those responsible for executing the plan to kill prosecutor Amauri Silveira Filho. Videos obtained by GloboNews show the meeting between the two investigated precisely in the days before the operation that ended up foiling the alleged murder plan. Itamar was arrested this Tuesday morning (9), at a site on the highway that connects Cardoso (SP) to the district of São João do Marinheiro. According to the prison record, Itamar did not offer any resistance, and after a forensic examination, he was sent to the Catanduva Public Prison (SP). Itamar had already been arrested in 2008 and ended up expelled from the Civil Police after being convicted of an extortion case. On that occasion, according to the Public Ministry's complaint, he and two other police officers arrested a woman being investigated for drug trafficking and demanded money from an alleged leader of the gang to release her.
