The Alfred P. Murrah Federal Building was a United States federal government complex located at 200 N.W. 5th Street in downtown Oklahoma City, Oklahoma. On April 19, 1995, the building was the target of the Oklahoma City bombing by Timothy McVeigh and Terry Nichols, which ultimately killed 168 people and injured 684 others. A third of the building collapsed seconds after the truck bomb detonated. The remains were demolished a month after the attack, and the Oklahoma City National Memorial was built on the site.
