An international forensics group in 2017 raised doubts as to whether Neruda died of prostate cancer at age 69 and did not rule out foul play.

Previous tests have found no evidence Neruda, winner of the Nobel Prize for literature in 1971, was poisoned.

The report's coordinator, Dr Gloria Ramirez, made no comment on Reyes' speculation about its findings, whose presentation to the court was delayed twice. It has not been made public because of judicial rules governing the inquiry.

Judge Paola Plaza, who is overseeing the case, said there is no deadline on delivering a verdict.

Neruda was a friend and adviser to Chilean socialist President Salvador Allende, who was overthrown in a coup led by Augusto Pinochet in September 1973.
