Investigators exhumed the body of a prime minister killed in a 1980 plane crash to look for evidence that the aircraft was brought down by a bomb.
The crash had been blamed on technical failure, but evidence has emerged recently to suggest a bomb was placed on board the plane of Prime Minister Francisco Sa Carneiro.A British laboratory determined last spring that the plane's fuselage contained traces of explosives. Sa Carneiro's body was exhumed so Portuguese forensic experts can search for traces of metals in it.
The twin-engine Cessna went down Dec. 4, 1980, just after taking off from Lisbon for the northern city of Oporto. All eight people on board were killed, including Defense Minister Adelino Amaro da Cos-ta.
A parliamentary commission ruled in June there was a likelihood that a bomb caused the crash.
