Rodrigo Castanheira's family lawyer, Albert Halex, declared that the teenager's death was a result of a 'premeditated homicide' carried out by a group rather than a spontaneous act. He emphasized that the attack on Castanheira was organized, suggesting a conspiracy that involved multiple participants, all of whom should be held accountable for the crime. Halex has indicated that there are additional elements in the case that point to the involvement of more individuals beyond those directly implicated.

The incident reportedly originated from a conflict between Castanheira and a younger schoolmate, who is believed to have instigated the assault. The lawyer cited jealousy and ongoing animosity as potential motivations behind the attack, mentioning that Castanheira had considered changing classes due to the harassment from this younger peer. This context underscores the complexities of adolescent relationships that may have escalated to violence, reflecting deeper social issues within school environments.

The police have acknowledged that the investigation is being handled seriously, suggesting that they are looking into the connections between the individuals involved and the events leading up to the homicide. This case highlights the challenges of addressing youth violence in schools and the need for intervention strategies to prevent such tragic outcomes in the future.
