At least six families have approached the Federal District Civil Police reporting suspicious deaths at Hospital Anchieta in Taguatinga, following the arrest of three nursing technicians accused of killing patients in the ICU. Confirmed victims include a Caesb server, a Correios employee, and a retired teacher, who died between November and December 2025 from injections of lethal substances. The probe points to possible psychopathic motives by the main suspect, with more deaths under review.
Hospital Anchieta in Taguatinga spotted atypical circumstances in three ICU patients and, in under 20 days, launched an internal probe and reported the case to the Federal District Civil Police, fully cooperating with authorities. The deaths occurred between November 17 and December 1, 2025: João Clemente Pereira, 63, Caesb server; Marcos Raymundo Fernandes Moreira, 33, Correios server; and Miranilde Pereira da Silva, 75, retired teacher.
Civil Police launched Operation Anúbis on January 11, 2026, with temporary arrests of two suspects and searches in Taguatinga, Brazlândia, and Águas Lindas. Phase two on January 15 arrested the third in Ceilândia and Samambaia. Technicians Marcos Vinícius Silva Barbosa de Araújo, 24; Amanda Rodrigues de Sousa, 28; and Marcela Camilly Alves da Silva, 22, face qualified homicide charges, with 9 to 30 years penalties. They allegedly injected irregular medications and disinfectant into veins, causing cardiac arrest in seconds.
The defense of Marcos Vinícius, via lawyer Marcus Martins, states facts are under police inquiry, with no conviction or crime recognition. "It is emphasized that there is no condemnatory sentence, nor judicial pronouncement recognizing the commission of a crime by the investigated," he declared. Claims about the suspect's personal life are deemed untrue.
Delegate Maurício Iacozzilli from the Homicide Repression Coordination says the main hypothesis is Marcos Vinícius acted for pleasure, as a psychopath. "So far, this is the strongest hypothesis," he said. The other two technicians allegedly assisted: one watched without intervening, the other guarded the door. Footage shows the trio acting. The lead suspect's accounts, like stress or mercy, do not hold, as one victim was conscious for intestinal constipation.
At least six families reported other suspicious deaths post-arrests. Police suspect more victims at the hospital and other public/private facilities, planning a new inquiry. Forensics on seized phones and computers should clarify motives in 15 to 20 days. The hospital reaffirms transparency and ethics in cooperation.
