A murder trial in Primavera do Leste, Mato Grosso, involving three defendants—including two prison officers—has been postponed following the dissolution of the Jury Council. The case concerns the 2018 homicide of Giovanni Henrique Oliveira Lopes.

The proceedings were interrupted after the defense presented a confidential report that was reportedly missing from the case files during a jurisdictional transfer from Poxoréu to Primavera do Leste. Prosecutors from the Mato Grosso Public Ministry (MPMT) challenged the use of this document. Following the dissolution of the council, the judge has rescheduled the trial for January 20, 2027.
