[6] In June 2019, Bispo's pre-trial detention was converted into an indefinite internment in the federal penitentiary [pt] of Campo Grande, capital city of Mato Grosso do Sul.

According to the expert, it all started with the rivalry between the PT and the Brazilian Social Democracy Party (PSDB), which created jargon such as “coxinha” and “petralha”, and there was also society's inclination to lynch people rather than do justice.

[23] The perpetrator of the attempted murder was arrested in the act by the Federal Police and identified as Adélio Bispo de Oliveira (Montes Claros, May 6, 1978).

[32] After listening to more than thirty people and breaking Adélio's financial, telephone and telematic confidentiality, federal delegate Rodrigo Morais and his team found no evidence that the perpetrator of the stabbing had acted at the behest of another person or group.

[7] The high degree of complexity of the surgery Bolsonaro underwent made it impossible for him to continue campaigning in the 2018 elections in the traditional way, due to the minimum recovery time of one to two months.

The bulletin said that “the abdominal condition has improved in the last 24 hours and the patient persists in intensive care and with progress in the time spent out of bed and walking".

[40] The second bulletin, released on September 10, stated that Bolsonaro's condition was serious and that another surgery would be performed in the future to reconstruct the intestinal transit and remove the colostomy bag.

[6][65] However, in a second investigation, opened on September 25, 2018, the PF is delving deeper into Adélio's possible connections by analyzing more than 6,000 cell phone conversations, more than 1,000 emails and telephone data from the last five years, as well as the source of the attacker's defense funding.

[69][70] In addition, suspicions were raised about posts on social networks that suggested that other demonstrators were co-perpetrators of the crime, promoting harassment and threats against these users.

A Federal Police investigation confirmed the officer's identity as Luiz Felipe Félix, and it was revealed that he had to be relocated due to the hostility he faced from the false accusation.

The Federal Police inquiry concluded that “the data from phones, computers, diaries, notes, emails, and social media, as well as fieldwork and interviews, failed to produce any evidence or even suspicions of complicity or participation by members of PSOL or PSD in the attack on then-candidate Jair Messias Bolsonaro".

The issue resurfaced in 2022 following the assassination of Marcelo Arruda, when Bolsonaro referenced Adélio's PSOL membership to defend himself from accusations of political violence.

The theory was supported by Ana Paula Henkel on January 4, 2022, during the "Pingos nos Is" program on Jovem Pan, suggesting that Adélio might have had a false alibi.

[74] In 2019, a false claim spread that the Federal Public Prosecutor's Office (MPF) had identified R$50,000 in deposits from Jean Wyllys to Adélio's lawyer.

[75] In the same year, Regina Villela, a Social Liberal Party (PSL) candidate for federal deputy in Ceará, posted a video making a series of accusations against Wyllys.

[81] Other prominent figures who have endorsed similar conspiracy theories include Jair Bolsonaro, Marcos Feliciano (who was ordered to pay R$41,800 in compensation to Wyllys), Marcos do Val (also ordered to pay R$41,800, with a daily fine if he fails to delete his social media posts), Olavo de Carvalho (who was instructed to delete posts within 48 hours and pay Jean R$10,000 if he did not comply), Carlos Bolsonaro, Eduardo Bolsonaro, Bia Kicis, Bibo Nunes, Frederick Wassef [pt], Ed Raposo, and Otávio Fakhoury.

[82][83][84] On September 8, 2018, Bolsonaro engineer Renato Henrique Scheidemantel accused PT banker and trade unionist Lívia Gomes Terra on his Facebook page of having given the knife used in the crime to Adélio.

The image was originally published on April 6, 2018, on the G1 news portal, entitled "Lula spends the early hours of the morning at the ABC metalworkers' union after arrest order.

[97] On February 14, 2022, fake news circulated that hacker group Anonymous had released a new statement by Adélio Bispo, in which he admitted that he had been hired by the Workers' Party.

[99] In 2018, rumors surfaced claiming that Manuela d'Ávila, a member of the Communist Party of Brazil (PCdoB) and Fernando Haddad's running mate during the 2018 elections, made between 6 and 18 calls to Adélio Bispo on the same day as the attack.

[101] Substitute Justice of the Superior Electoral Court, Carlos Horbach [pt], ordered Facebook to provide the IP address and other details about the page's administrators.

[73] On the day that Adélio Bispo was acquitted on the grounds that he was incompetent, a rumor emerged that he had his telephone and bank secrecy protected by the Order of Attorneys of Brazil (OAB).

[107] On April 24, 2020, then-Minister Sergio Moro left the Ministry of Justice, accusing President Jair Bolsonaro of interfering in the Federal Police.

[110] Alexandre Ramagem, director of Brazilian Intelligence Agency (ABIN), allegedly called Bolsonaro to say that Moro and Maurício Valeixo were hiding information about the case.

[113][114] The apparent absence of blood at the scene of the stabbing and the quick medical and police response are considered signs by proponents of the theory that the whole event was staged.

Former president Luiz Inácio Lula da Silva has also expressed doubts about the attack, stating in an interview that he found the inaction of security personnel strange.

[116] In September 2021, federal deputy Alexandre Frota submitted a request to open a Parliamentary Inquiry Committee (CPI) to investigate the case.

YouTube claimed that its hate speech policy prohibited the denial, trivialization, or minimization of historical events, including the stabbing of Jair Bolsonaro.

[121] President Michel Temer described the attack as intolerable, reiterating his outrage at the lack of harmonious coexistence in a democratic rule of law, where a peaceful campaign should be feasible.

[122] General Hamilton Mourão, Bolsonaro's running mate, commented that the campaign needed to "put an end to the victimization" surrounding the attack.
