emilio eduardo massera -lrb- october 19 , 1925 -- november 8 , 2010 -rrb- was an argentine naval military officer , and a leading participant in the argentine coup d'état of 1976 .
in 1981 , he was found to be a member of p2 -lrb- also known as `` propaganda due '' , a clandestine masonic lodge involved in italy 's strategy of tension -rrb- .
many considered massera to have masterminded the junta 's dirty war against political opponents , which resulted in nearly 13,000 deaths and disappearances , according to official records .
human rights groups put the toll closer to 30,000 .
