Dan Mitrione never heeded the warnings. It was too late to take on additional security measures, although according to a RAND Corporation study he had previously been warned of the inherent risks of his position, when five men approached his car on the residential streets of Montevideo, Uruguay on the morning of July 31, 1970 and rammed into his vehicle with one of their two stolen pick-up trucks. Within moments, Mitrione’s police chauffeur had a weapon pointed at him by the attackers and never used his .38 revolver. Mitrione, the chief of a small police training team in the Office of Public Safety (OPS) with the United States Agency for International Development (USAID), was unarmed and he was soon removed from the vehicle. The attackers, from a Marxist–Leninist urban guerrilla group known as the Tupamaros, cursed and beat Mitrione as they moved him into the trunk of the other undamaged pick-up truck. While laying down, Mitrione was shot by one of the kidnappers in the shoulder, his blood later found by the authorities in the truck along with some of his belongings.
