SANTIAGO, Chile — A scientific autopsy has confirmed that Chilean President Salvador Allende committed suicide during the 1973 coup that toppled his socialist government, court officials announced on Tuesday.

British ballistics expert David Prayer said Allende died of two shots fired from an assault rifle that was held between his legs and under his chin and was set to fire automatically. The bullets killed him instantly.

The forensics team’s conclusion is unanimous, Spanish expert Francisco Etxeberria said: “We have absolutely no doubt” that Allende committed suicide.

Prayer said there is no evidence a second person was involved in Allende’s death. That ruled out theories that Allende, the first socialist in the Americas to come to power at the ballot box, was killed by the military during the coup led by Gen. Augusto Pinochet.
