Brasilia – The family of Chilean poet Pablo Neruda, winner of the Nobel Prize for Literature in 1971, has agreed to send his remains to the United States for a series of toxicological tests. Neruda's remains, who died in September 1973, were exhumed last Monday (8) by Chilean authorities in an effort to determine if his death was caused by poisoning.

Neruda died shortly after the coup d'état in which General Augusto Pinochet seized power in Chile. At the time, the poet's death was attributed to prostate cancer. However, an advisor to Neruda has stated that he received a lethal injection on Pinochet's orders.

Lawyer Rodolfo Reyes, Neruda's nephew, who witnessed the exhumation of the body along with a group of international experts, told a Chilean radio station that his uncle's remains will be thoroughly examined. "They will take samples to a laboratory. It's a technical examination, and we want them to take as much time as necessary so that there are no doubts," Reyes said.

The tests will be conducted in North Carolina.

Neruda was a friend of Chilean President Salvador Allende, who was deposed by Pinochet. The poet died at the age of 69, just 12 days after the coup, and was buried in the garden of his home in Isla Negra, on the coast of Chile, where his wife Matilde Urrutia was also buried in 1985.

In 2011, Chile began investigating allegations by Manuel Araya, Neruda's former driver and personal assistant, regarding the alleged poisoning of his employer. Araya claims that Neruda called him from a hospital and said he began feeling unwell after receiving an injection. These allegations are supported by the Chilean Communist Party, which maintains that Neruda showed no symptoms of cancer when he died.
