Christian Democrat President Aldo Moro was abducted on Via Fani, Rome, on 16 March 1978 — the morning of the swearing-in of his 'compromesso storico' coalition with the PCI. A five-member Brigate Rosse team led by Mario Moretti killed Moro's five escort officers in the ambush. Moro was held 55 days; nine letters from captivity were sent to his family and the Italian government. The State refused all negotiation. His body was found in the trunk of a Renault 4 on Via Caetani on 9 May 1978. Moretti received a life sentence in 1983; Prospero Gallinari and Anna Laura Braghetti were also convicted. Parliamentary commissions (1979–83, and a special commission in 2014) identified anomalies in the original investigation, with allegations of overlap with the NATO stay-behind network Gladio and a broader 'strategy of tension'.
