Mario Alberto Canales Najjar was a lawyer who practiced in Mexico but also served as president of the Mexican Hunting Federation, a position he had held since 2018.

Najjar was gored by the buffalo weighing more than a ton during a hunting trip with three friends in the Argentine province of Entre Ríos, in a location called Punta Caballos around 124 miles north of Buenos Aires.

He later died at the age of 64 due to the nature of his injuries—which included multiple rib and sternum fractures, as well as injuries to the abdomen—local daily UNO reported.

Before the buffalo charged at him, Najjar had shot the animal with his .408-caliber rifle but this was not sufficient to kill the large mammal.

After being shot, the buffalo ran at him, ramming the hunter with his horns. The attack only stopped after the tour guide who was accompanying the group shot the buffalo five times with his .458 caliber rifle, eventually killing it.

The group was in a remote area and did not have cellphone reception to call an ambulance so they loaded Najjar into a truck and rushed him to a nearby hospital in a state of shock. But the hunter was pronounced dead at the scene.

Following the hunter’s death, the public prosecutor’s office in Entre Ríos opened an investigation into the incident.

This investigation found that the adventure tourism company that the group hired was not authorized to carry out such activities in the area and that the group only had permission to hunt pigeons not large animals.

The prosecutor said the hunter “knew the activity he was carrying out and the risk in which he was involved.”

Despite the fact the group had no permit to hunt buffalo, the prosecutor determined there would be no further investigation into the incident and that the case would be filed away.

This is not the only recent case of a hunter being killed by an animal that was meant to be their trophy. In June this year, a dying bear that had been shot by a hunter in Russia managed to kill the 62-year-old by crushing the man’s skull, the news agency Interfax reported. The incident occurred in the Tulun district of the Irkutsk region of Russia.
