The inquiry that followed would account for 1,056 buffaloes and 72 horses and mares on the Água Sumida farm. The animals had been left in a stretch of land stripped of vegetation, with no trough, spring, or river within reach. Douglas Brandão do Amaral, the police chief who took the case, described watching the pasture being deliberately ruined the day before the arrest - a tractor tearing up grass that was still good. His conclusion was blunt. "We saw that his intention, I still don't know for what reason, was to kill these buffaloes," he said. Because he read the destruction as deliberate, he charged the case in material competition: not one count of animal mistreatment, but one count for every animal. Luiz Augusto Pinheiro de Souza, the farm's owner, was arrested on November 11, 2021.

Água Sumida means vanished water, and the name turned out to be a grim accident of geography. Investigators later concluded that the pastures had been given over to soybean cultivation, the herd left in place as the fields around it changed use. Animals died. More than a hundred are recorded as having perished during the abandonment, and officers found carcasses on the property - some in the open, others that investigators came to suspect had been buried there. These were not statistics on a page. They were pregnant water buffalo, animals bred for docility and dependence, standing in a field waiting for feed that never came. Souza denied that he had abandoned the herd at all.

The story moved fast through Brazilian media. Newspapers, television, and the Sunday newsmagazine *Fantástico* covered it; celebrities amplified the appeals; animal-protection organizations mobilized to keep the surviving animals alive. Souza had already been fined R$2.13 million over the treatment of animals before this case broke, and fines imposed by the Environmental Police in connection with the Brotas herd reached R$3.5 million. Taken together, prosecutors calculated, the charges could theoretically total 500 years in prison. There was an awkward local footnote, too: Souza owned a restaurant in Brotas called Fatto di Bufala, its menu built partly on cheese made from the milk of the species now starving on his land. After the case broke, he sent a message to Brotas mayor Leandro Corrêa, who said he felt intimidated by it and passed the material to the investigating police chief.

Rescue is the dramatic word, but what actually happened afterward was slower and less cinematic. The surviving buffaloes stayed where they were, and an animal-protection organization took over their daily care - hay, water, veterinary attention, hired hands - at a running cost of tens of thousands of reais every month. Ownership of the herd was disputed in court between the farmer and the NGO while the feeding continued. Dry-season drought made it harder still; in the months when the pasture browns and the rivers drop, keeping more than a thousand large animals fed became a logistical problem measured in truckloads. Donations carried much of it. Public attention, which arrives in a rush, has to be converted into something that lasts years.

In January 2025, more than three years after the tip, a court convicted Souza of mistreating the animals. The sentence came to four years, seven months, and ten days combined - one year of reclusão plus three years, seven months and ten days of detention - both to be served initially in a semi-open regime, along with 128 day-fines set at the minimum wage of the time. Souza said he would appeal and, under the ruling, was permitted to do so while remaining free; custody of the herd, already transferred to an animal-welfare organization back in November 2021, was not returned to him. It is a modest number of years against the arithmetic prosecutors once floated, and animal-welfare advocates said so. But the conviction established something Brazilian courts have rarely stated so plainly: that leaving livestock to die of thirst is not a business decision gone wrong. It is a crime, counted animal by animal.
