According to the complaint, the accused introduced himself as doctor Jeferson Targino Sampaio and, using his name and professional registration, carried out consultations, prescribed medications, requested tests and accompanied a 10-year-old patient, diagnosed with grade IV medulloblastoma, between October 2025 and August 2026.
During the investigation, among other items, stamps and prescription pads in the name of Jeferson Targino Sampaio were seized, as well as special control prescription pads in the name of another professional. An expert report attached to the case concluded that the material was in usable condition and could be used for someone to present themselves as a doctor.
Elements relating to the possible role of the accused in other services were also incorporated into the case file. Among them, there is an incident record in which a representative of a clinic reported that Diogo had introduced himself as Jeferson Targino Sampaio and carried out approximately 230 admission exams. These facts will still be subject to investigation during the process.
Upon receiving the complaint, judge Guilherme Grandmasson Ferreira Chaves considered the legal requirements for the initiation of criminal action to be present.
“The complaint contains the presentation of the criminal facts with their circumstances, the qualification of the accused, the legal classification of the conduct and the list of witnesses, and is accompanied by elements that provide the necessary just cause for the initiation of the criminal action.”
The judge also rejected the request to revoke the preventive detention and the subsidiary request for replacement by various precautionary measures.
In the decision, the court highlighted that the maintenance of the prison does not result from the abstract seriousness of the accusations, but from the concrete circumstances described in the case file, especially the duration and form of action attributed to the accused and the risk of repetition.
“I therefore maintain the preventive detention of Diogo dos Santos Serpa, to guarantee public order, given the concrete and contemporary risk of repeating the crime, as the assumptions and requirements set out in articles 312 and 313 of the Code of Criminal Procedure remain present.”
The decision also determined that steps should be taken to further the investigation, including the provision of the patient's full medical records by the institutions involved and the carrying out of a medical-expert assessment, to analyze the conduct attributed to the accused in light of the child's clinical condition.
