At least 17 people died and 29 were injured when a truck crashed on a road in the central Bolivian province of Cochabamba over the weekend, police said Monday.
The accident occurred on Saturday, but no announcement of it was made until Monday.
The truck plunged some 100 meters (about 330 feet) into a ravine on the road linking the rural towns of Kami and Independencia.
It is strange that the relatives of the victims did not ask authorities to recover the bodies or help the injured, the head of the Cochabamba highway authority, Col. Alberto Antezana, told the official ABI news agency.
Fifty people were said to be riding in the truck, most of them men from the town of Charahuayto who were en route to the village of Parte Libre after attending an agricultural fair, Independencia Mayor Gonzalo Calcina said.
All the victims were buried on Sunday, and the injured - including the driver of the truck - are being treated in hospitals in the cities of Vinto, Quillacollo and Cochabamba, Calcina said.
Every year, according to government figures, road accidents in Bolivia kill an average of 1,000 people and injure 40,000.
