There is less information about the murderer.

It was recently known that a solider of the notorious military brigade of the state confessed to the crime, after seeing evidence against him. He was later removed from office.

Despite this, the top public security officers of Rio Grande Do Sul decided to keep the criminal’s name in secret as, they claimed, this does not hinder the ongoing investigation.

All the interrogations on the case can last over 40 days.

The local organizations criticized the covering up of the Public Security officials and demand that the rest of the society should know the identity of the killer.

The crime took place during the MST’s National Day of Struggle for the Agrarian Reform, outside one of the rural facilities of Alfredo Southall.

That day, 300 police officers participated in the violent eviction of 550 landless activists who had been occupying the estate since August 12.

Brum da Silva was shot in the back, while tens of people were injured.

The bullet that killed him, according to testimonies, was fired when the situation was already under control and there was no resistance from the demonstrators.

The days that followed this tragic event, thousands of voices raised to condemn the repression.

Most of the criticism came from the state governor, Yeda Crusius, of the right-wing Party of the Brazilian Social Democracy (PSDB), which has now become a symbol of the criminalization of the social protest.
