Samuel Doe, who took power in Liberia as an army master sergeant in 1980, was seized at Monrovia's Freeport by fighters of Prince Johnson's Independent National Patriotic Front and tortured to death. He had gone to the port to see the commander of the West African peacekeeping force ECOMOG, whose soldiers disarmed his escort on arrival. A witness later told Liberia's Truth and Reconciliation Commission that Johnson led Doe away in front of the ECOMOG commander, who turned his back and walked into his office.
