The Brazilian truth commission has concluded that former president Juscelino Kubitschek was not murdered by the military regime, but died in a car accident. Kubitschek, who was an opposition leader at the time, died on 22 August 1976 following a car accident on a motorway between Rio de Janeiro and Sao Paulo. His driver was also killed.
Just as with other prominent deaths during the dictatorship-era in Latin America (Pablo Neruda, Joao Goulart, Salvador Allende...), there have been persistent rumours that the car crash may not have been all it appeared. In fact, a Sao Paulo truth commission declared that it had evidence that Kubitschek had been murdered. The national commission, however, disagrees. Its coordinator Pedro Dallari said it was "quite sure" it's version of events was accurate and that it had "not been convinced" of the version put forward by the Sao Paulo commission.
