The Oklahoma City bombing was a domestic terrorist car bombing of the Alfred P. Murrah Federal Building in downtown Oklahoma City, in the state of Oklahoma, on April 19, 1995. Carried out by Timothy McVeigh and Terry Nichols, the bombing destroyed one-third of the building, killed 168 people, and injured more than 680 others. The blast destroyed or damaged 324 other buildings within a 16-block radius, shattered glass in 258 nearby buildings, and destroyed or burned 86 cars, causing an estimated $652 million worth of damage. Extensive rescue efforts were undertaken by local, state, federal, and worldwide agencies in the wake of the bombing, and substantial donations were received from across the country. The official investigation, known as "OKBOMB", saw FBI agents conduct 28,000 interviews, amass 3.5 short tons of evidence, and collect nearly one billion pieces of information. The bombers were tried and convicted in 1997.
