Alessio Casimirri (born 1951) is an Italian terrorist and member of the Red Brigades (BR), currently fugitive.
Casimirri was born in Rome. His mother was a Vatican City citizen, and his father had worked for the Vatican newspaper L'Osservatore Romano and as the public relations man for three Popes.
After a militancy in Potere Operaio and other far-left organizations in Rome, he entered the Red Brigades. He was condemned in absentia to life imprisonment for the assassination of Aldo Moro's escort in 1978. In 1980 he abandoned the BR and subsequently fled abroad, reaching Nicaragua after a period in Libya and Cuba. In the Central American country he participated in the Sandinist guerrilla against the Contras, after which, together with other Italian expatriates, he opened a restaurant in Managua, called Magica Roma[1].
Thanks to his Nicaraguan citizenship, obtained through his marriage with a local woman, he could not be extradited to Italy, despite the repeated requests of Italian magistrates[2].
