The Mastermind Behind the Library Heist

The investigation into the bold daylight robbery, which occurred on a Sunday morning at the Mário de Andrade Library, has widened significantly. Authorities have now named Laéssio Rodrigues de Oliveira Silva as the architect of the plot. According to ArtReview, Rodrigues de Oliveira Silva was already in custody at the time of his identification, serving time for an attempted bribe of a security guard at the Rui Barbosa Institute in Rio de Janeiro. His criminal history is extensive, particularly regarding the theft of rare books and cultural artifacts. In 1998, he was convicted for stealing rare magazines from the National Library Foundation, a collection valued at US$750,000 at the time. Police allege that Rodrigues de Oliveira Silva leveraged his time in prison to establish connections with the PCC, an organized crime gang with international reach. Investigators recovered a voicemail from his phone in which he explicitly boasted about his focus on high-value literature: “My real specialty is books. My business is books. Very valuable, very rare books. I distribute them all over the world. I’m getting into the art business now.”

The Mechanics of the Robbery

The heist itself was a calculated operation. Two armed men entered the library, which is recognized as the largest in the country, and subdued both a security guard and an elderly couple. The suspects then disabled the steel cables securing the artworks before placing them into a canvas bag and fleeing through the main exit. “The pair broke into the location, known for being the largest library in the country, overpowered a security guard and an elderly couple, and placed documents and eight paintings in a canvas bag. They then fled through the main exit.”São Paulo Civil Police, via NBC News The stolen collection included eight prints from the Henri Matisse “Jazz” series (1947) and five illustrations by Candido Portinari created for the 1959 book “Menino de Engenho.” As NBC News reported, the Museum of Modern Art of São Paulo (MAM-SP) confirmed the theft, noting the pieces were part of a partnership exhibition titled “From Book to Museum: MAM São Paulo and the Mário de Andrade Library.”

Suspects, Intermediaries, and the Search for “Gargamel”

The investigation has led to a web of arrests beyond the alleged mastermind. Police have apprehended Carlos Leandro Ferreira da Silva and a law student, Regiane Rodrigues da Silva, who are accused of acting as intermediaries between the mastermind and the men who physically carried out the theft. One of the two men who entered the library, Gabriel Pereira Rodrigues de Mello—often referred to by the nicknames “Gargamel” and “Capybara”—remains a primary target for law enforcement. According to The Art Newspaper, Mello had prior convictions for robbery and aggravated theft that were dismissed early last year under a law granting pardons for time served and good behavior. His history includes a 2022 incident where he impersonated a bank employee to steal an envelope containing 300 reais ($55).

Cultural Stakes and Recovery Efforts

The economic value of the missing works is estimated between 700,000 and 1 million reais, or approximately $130,000 to $185,000. However, officials emphasize that the loss transcends simple financial metrics. São Paulo’s Municipal Secretariat of Culture and Creative Economy stated that the stolen items “have cultural, historical, and artistic value and cannot be assessed solely in economic terms.” Recovery efforts are currently being coordinated across several major Brazilian institutions, including the Brazilian Institute of Museums and the National Institute of Historical and Artistic Heritage. Mayor Ricardo Nunes has confirmed that Interpol has been notified to monitor international transit points in an attempt to prevent the artworks from leaving Brazil. As of late May 2026, the pieces remain missing, and the search for Mello continues.
