The death of 37-year-old physician Gassi Paola de Souza Mazia in Maringá, Paraná, is being investigated as a suspected femicide. Mazia, who worked for the public health system in Sarandi, was found dead in her apartment alongside her eight-month-old son.

Initial reports identified her partner, 25-year-old João Vitor Domingues Romeiro, as a suspect who was arrested after being located in Mandaguari. Subsequent forensic reports confirmed that Mazia died from acute hemorrhage resulting from 14 stab wounds and also suffered strangulation. Investigators believe the attack followed a dispute regarding the end of the couple's relationship. Romeiro, a former administrative legal advisor for the Marialva City Hall, reportedly confessed the crime to a family member.
