The femicide of Cibele Monteiro Alvesaged 22, committed by Cássio Henrique da Silva Zampieri, aged 25, would have been motivated by the suspect’s non-compliance with the end of relationshipwhich took place about nine months ago, in April 2025.
Cibele was stabbed to death on Wednesday night (25), while working at a Vivara store in Golden Square Shopping, in São Bernardo do Campo, in ABC Paulista.
According to the incident report to which the CNN Brazil had access, the investigations indicate that Cássio did not accept the end of the relationship and demonstrated that he was unhappy with the situation.
For this reason, the victim had already registered three police reports against him and obtained one, which prohibited him from maintaining contact.
