The Oklahoma City bombing was a domestic terrorist attack on April 19, 1995 aimed at the U.S. government in which the Alfred P. Murrah Federal Building, an office complex in downtown Oklahoma City, Oklahoma, was bombed. The attack claimed 168 lives and left over 800 people injured. It was the first major terrorist attack and until the September 11, 2001 attacks, it was the deadliest act of terrorism on U.S. soil.
Shortly after the explosion, Oklahoma State Trooper Charlie Hanger stopped 26-year-old Timothy McVeigh for driving without a license plate and arrested him for that offense and for unlawfully carrying a weapon. Within days after the bombing, Timothy McVeigh and Terry Nichols were both arrested for their roles in the bombing. Investigators determined that they were sympathizers of a militia movement and that their motive was to retaliate against the government's handling of the Waco and Ruby Ridge incidents (the bombing occurred on the anniversary of the Waco incident). McVeigh was executed by lethal injection on June 11, 2001. Nichols was sentenced to life in prison. A third conspirator, Michael Fortier, who testified against McVeigh and Nichols, was sentenced to 12 years in prison for failing to warn the U.S. government. As with other large scale terrorist attacks, conspiracy theories dispute the official claims and point to additional perpetrators involved.
