The Alfred P. Murrah Federal Building was a government office building located in downtown Oklahoma City, Oklahoma. Completed in 1977, it housed various federal agencies, including the Social Security Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives. The building was named after Alfred P. Murrah, a former federal judge. On April 19, 1995, the building was the target of a devastating terrorist attack carried out by Timothy McVeigh. A truck bomb exploded outside, resulting in the deaths of 168 people and injuring over 600 others. The attack remains one of the deadliest acts of domestic terrorism in U.S. history.
