The April 19, 1995 truck bombing of Oklahoma City’s Alfred P. Murrah Federal was the deadliest act of domestic terrorism in American history One hundred and sixty-eight people, including nineteen children, were killed and hundreds more injured by an ammonium-nitrate and fuel-oil (ANFO) bomb hidden in a rental truck parked outside the building’s entrance. The attack precipitated the largest manhunt in US history Two US army veterans, Timothy McVeigh and Terry Nichols, were put on trial by federal authorities for their role in the attack. In June 1997 McVeigh, the actual bomber, was convicted and sentenced to death in the federal district court in Denver. Terry Nichols was sentenced to life in prison for his role in the bombing. The attack was motivated by intense hostility towards the federal government, generated by the fiery end to the Branch Davidian/Waco stand-off on April 19, 1993.
