The São Paulo Civil Police are conducting an investigation into the circumstances surrounding the death of swimming instructor Juliana Bassetto, who died following a swimming class at C4 Gym. Authorities suspect that the gym's owner, Severino José da Silva, deleted WhatsApp messages exchanged with an employee responsible for maintaining the pool, which may reveal critical instructions regarding the use of chemicals. Reports indicate that the employee was given directives despite lacking the technical qualifications for such tasks.

According to delegate Alexandre Bento, the conversation logs indicated the owner provided specific guidance on chemical usage, which could have contributed to a hazardous environment. The main theory posited by investigators is that improperly handled chemicals in a poorly ventilated indoor space may have led to the release of toxic gases, causing the unfortunate incident. This situation emphasizes the potential dangers associated with inadequate safety protocols in fitness facilities.

As the inquiry progresses, the actions of the gym owner are under scrutiny, especially regarding whether he attempted to evade accountability for the incident by deleting pertinent communication. This case raises significant concerns about regulatory compliance in gyms and the responsibilities of business owners towards ensuring the safety of their clients and staff.
