The Chilean government is launching its first investigation into the death of socialist president Salvador Allende, who died during the country's 1973 coup.
Until now Mr Allende's death, during the bloody US-backed coup that brought military dictator Augusto Pinochet to power, had been ruled a suicide.
On September 11, 1973, soldiers were surrounding Chile's presidential palace and planes had begun to drop bombs.
When soldiers entered the palace they say they found Mr Allende dead by his own hand.
They claimed he killed himself with an AK-47 rifle given to him by Fidel Castro.
But many still dispute that conclusion, saying it did not fit with their understanding of the man.
Now they may have an opportunity to get to the truth.
The probe is part of the investigation of hundreds of human rights complaints against Pinochet's 1973-1990 military dictatorship.
