Pablo Neruda during a Library of Congress recording session, 20 June 1966The death of Pablo Neruda, the Chilean poet who mysteriously died in a hospital just days after an oppressive regime came to power in his country, has long been considered suspicious.

His remains were exhumed in 2013, and forensic results didn’t reveal any poison – but they did identify strange bacteria. Now DNA results on the suspicious bacteria that could finally solve the mystery are expected next month, according to reports on teleSUR.

Neruda’s death in 1973 was originally attributed to advanced prostate cancer by the doctors in the Chilean hospital. But Neruda had not been known to have been mortally sick.

The poet was even planning to make a trip to Mexico to join opponents of dictator Augusto Pinochet, who had taken power just 12 days earlier.

Neruda’s chauffeur told a Mexican magazine in 2011 that Neruda, a Communist sympathizer, was killed by agents of Pinochet. The Nobel laureate was murdered by an injection into his stomach, the chauffeur claimed, prompting the exhumation of the body.

Tests proved inconclusive.

No chemical or poison was found in the bones. A new round of testing began in January 2015 – unearthing three bacteria within the bones. Two of the varieties could be explained by the poet’s prostate cancer. But the third, showing staphylococcus bacteria, did not necessarily fit the disease, said a group of forensic experts from Spain.

In November, the Chilean government admitted the 1971 Nobel Laureate could have been assassinated.

Judge Mario Corroza said in court this week that the final test remaining would be a genomic test of the suspect bacteria, which would identify and trace the provenance of the strain.

The final results of the new investigation will be released in March, the judge added, ruling that Neruda’s remains should now be reburied.

Neruda was hailed as a genius during his lifetime. The Nobel Prize committee in 1971 specifically acknowledged him "for a poetry that with the action of an elemental force brings alive a continent's destiny and dreams."

“They all advise me rest,/ they all send me to the doctor,/ looking at me a certain way./ What happens?” he wrote in “The Fear.”

“They all advise me to travel,/ to come and to leave, to stay,/ to die and not to die./It does not matter.”

The Chilean political climate was extremely contentious, even deadly, in the 1970s. The former president of the country, Eduardo Frei Montalva, died in the same Santiago hospital as Neruda in 1982. Though Montalva’s death was initially credited to sepsis, a 2006 investigation concluded he had been assassinated with mustard gas and thallium, according to multiple reports of the time.

President Salvador Allende, the leader who was overthrown by Pinochet and died just days before his supporter Neruda, was also exhumed in recent years. However, investigators later determined he had committed suicide with his AK-47 shortly after giving a farewell speech to the Chilean people amid the chaos of the coup.
