In 2012, while Díaz travelled along the intersection of Route 2 and Route 86, he was hit by an all-terrain vehicle (known commonly as a 4x4). The vehicle then fled the scene. The vehicle that caused the accident was recognized by inhabitants of the area as that of the Celía family, who besides being close friends to government officials in Formosa, had already been accused of a previous attack against Díaz during the roadblock of the Route 86. After the incident gained public attention, Díaz was moved to an intensive therapy program and would publicly claim that the incident was an attack against his life and a direct result of the Qom's land dispute.
