The excavation of a burial site holding the remains of at least two people, and possibly dating from the era of military dictatorship, was being supervised by the Chilean authorities today.
The latest grave was found by a highway that links the capital Santiago with the small town of Curacavi, 50 kilometres (30 miles) northwest.
Mr Jaime Jimenez of the ruling Socialist Party told reporters local farmer Mr Pablo Escobar had told him he had found human remains at the site after the September 1973 coup which brought Augusto Pinochet to power.
The excavation of the grave is being supervised on site by investigating judge Wilfredo Orellano and other officials.
At the time, Mr Escobar had kept his discovery to himself, Mr Jimenez told reporters, and had covered over the grave with concrete.
He was "a person of good will who gave a Christian form of burial to the remains of two people, one adult and one minor," Mr Jimenez said.
