The caretaker, João José Romão, is the main suspect in the murder of his 21-year-old stepdaughter, Thaís Lorrany Soares Sales, who was shot and killed at a site in Cássia dos Coqueiros, São Paulo. According to the police, a letter found in the home where the incident occurred reveals that Romão claimed to have been jealous of the victim. He mentioned an alleged relationship he had with her and expressed dissatisfaction over her reluctance to continue it, despite the victim's family denying any such relationship existed.

In the letter, Romão detailed his turmoil over feelings of jealousy and possession, noting that he previously attempted to manage his feelings but ultimately succumbed to them, which led to conflicts with the victim. He described his obsessive control over her movements, stating that he forbade her from leaving the house, which he believed contributed to escalating disputes between them. This letter adds a troubling dimension to the case, hinting at underlying issues of possessiveness and emotional instability.

The circumstances surrounding Thaís' death and the contents of the letter have drawn attention to the potential psychological motivations behind domestic violence and jealousy. The investigation is ongoing, and as the authorities look deeper into the suspect's background, there may be broader implications for understanding similar cases of domestic abuse in Brazil.
