Its purpose is to preserve a collection composed of documents from police investigations, such as the different weapons used by civilians, typical jailhouse tattoos, traffic tragedies, objects used in crimes and all other situations involving criminality in São Paulo from the 20th century onwards.

[2] The Civil Police of the State of São Paulo was created in 1841 with the purpose of executing the orders of the Judiciary, as well as taking care of all criminal offenses that were not military or committed against the Union.

Three other names of great importance during this initial period were Jorge Tibiriçá, president of the state of São Paulo, who in 1905 launched José Cardoso's demands; Antônio de Godói, a police delegate who developed and consolidated the idea of creating careers; and Washington Luís Pereira de Sousa, Secretary of Justice and responsible for the first steps towards the desired "Career Civil Police of the State of São Paulo".

It is located in a building within the University City along with the Civil Police Museum, created in 1927 as a way of honoring and teaching about the changes and evolutions that have occurred since the beginning of the formation of the organization up to the present day.

[4][6] The museum's collection features typical objects used by civil police officers in the past, such as different types of weapons, and preserved documents and photos about the history of the organization.

Famous cases such as the Suitcase Crime, Chico Picadinho and the Park Maniac also feature in the site's collection, which has approximately 3,000 items - including old vehicles, drug exhibits, pieces from traffic accidents, fires, gun deaths, gambling machines, lie detectors, among others - that constitute the criminalistics and criminology archive.

Photos of crimes and objects related to the daily life of the São Paulo police are also on display for visitors to see, as well as simulated cases of murder and rape.

Committed by motorcycle courier Francisco de Assis Pereira, the acts occurred in the State Park, in the city of São Paulo, and were marked by the sexual assault and subsequent murder of the victims.

Survivors began to appear to assist in the search for the killer, contributing to the creation of a sketch and, later, the identification of the criminal, who was arrested just 23 days after his discovery and confessed to the murder of 15 women between 1995 and 1998.

Sexually abused by an aunt and forced to have homosexual relations with one of his bosses, Francisco developed disorders that eventually affected his behavior and created a "breast fixation" and impulses that he considered uncontrollable.

[17][8] At the entrance to the museum there is an exhibition of cars that were used by the civil police in previous decades, such as the Willys MB, which was used a lot during the military dictatorship, and the VW Variant, very common in the 80s.
