In Porto Velho, Brazil, a law professor named Juliana Mattos de Lima Santiago, aged 41, was tragically killed by a 24-year-old student, João Cândido da Costa Júnior, during a classroom attack. The incident, which took place after a brief discussion between the two, is currently under investigation as a femicide, highlighting the grave issues surrounding violence against women in educational settings. Evidence suggests that the attack was premeditated, as the student waited until after class to engage with the professor.

Witnesses reported that after the discussion turned violent, the student attacked the professor with a knife. Other students in the vicinity intervened, leading to the suspect's detention at the scene. Following the event, the local police quickly arrested him, and the judicial system has since escalated his charges from immediate arrest to preventive detention. This ensures that the suspect will remain in custody as investigations continue, reflecting the seriousness of the crime and the legal context surrounding violence within educational institutions.

The murder of Juliana Mattos not only raises alarms about gender-based violence but also sheds light on the safety of educators in academic environments. As the investigation unfolds, it is essential to consider the broader implications for university safety policies and support systems for both faculty and students. This incident could potentially lead to calls for more robust protection measures in universities across Brazil, as communities grapple with the shock of this violent act and its ramifications for public safety.
