# Violence and police investigations in São Paulo > Live situation record from CLSTR: https://clstr.news/situations/violence-and-police-investigations-in-so-paulo > Updated: 2026-10-24T00:22:42.000Z. Sources: 79. Developments: 5. Authorities in São Paulo continue to manage investigations into multiple violent incidents. Central to recent developments is the shooting of 20-year-old Gustavo Munis de Santana in the Moema neighborhood. During an intervention following reports of a potential suicide attempt, four Military Police officers fired 45 shots. While initial reports suggested Santana was struck 27 times, a forensic report from the Institute of Criminalistics has clarified that 12 shots hit the victim—including three to the chest and one to the abdomen—while eight others were glancing blows. While São Paulo’s Secretary of Public Security, Osvaldo Nico Gonçalves, has defended the intervention as legitimate self-defense, the incident remains under intense scrutiny. The São Paulo Public Security Secretariat (SSP) has suspended the four involved officers, three of whom are in their probationary period, and opened both a Military Police Inquiry (IPM) and a civil police investigation. Investigators are also examining a nearly six-hour delay between the shooting and the notification of homicide investigators. Santana’s family and their lawyer, Ana Facillia Meira, dispute the suicide attempt narrative and allege institutional violence. They claim Santana had no criminal record and was frequently targeted due to racial profiling despite living in an affluent area. This case has become part of a broader pattern regarding police responses to individuals in psychiatric crises. The deaths of Santana, Camila Pereira da Silva, and Antônio Nunes Batista have reignited demands for improved training and better coordination with health services, with families describing the use of force as “executions rather than assistance.” In a separate violent event in the Alto de Pinheiros neighborhood, criminals invaded the residence of Mitsuo Matsunaga, the former father-in-law of Elize Matsunaga, holding six family members hostage. ## Claims - Officers reportedly mistook a Samsung cellphone for a firearm.
