The Oklahoma City bombing was a domestic terrorist truck bombing of the Alfred P. Murrah Federal Building in downtown Oklahoma City, in the U. S. 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. Extensive rescue efforts were undertaken by local, state, federal, and worldwide agencies in the wake of the bombing, the Federal Emergency Management Agency activated eleven of its Urban Search and Rescue Task Forces, consisting of 665 rescue workers who assisted in rescue and recovery operations. Within 90 minutes of the explosion, McVeigh was stopped by Oklahoma State Trooper Charlie Hanger for driving without a license plate, forensic evidence quickly linked McVeigh and Nichols to the attack, Nichols was arrested, and within days, both were charged. Michael and Lori Fortier were later identified as accomplices, McVeigh, a U. S. militia movement sympathizer who was a Gulf War veteran, had detonated a Ryder rental truck full of explosives parked in front of the building. McVeighs co-conspirator, Nichols, had assisted in the bomb preparation, motivated by his hatred of the U. S. The official investigation, known as OKBOMB, saw FBI agents conduct 28,000 interviews, amass 3.5 short tons of evidence, the bombers were tried and convicted in 1997. McVeigh was executed by lethal injection on June 11,2001, as a result of the bombing, the U. S. On April 19,2000, the Oklahoma City National Memorial was dedicated on the site of the Murrah Federal Building, commemorating the victims of the bombing, annual remembrance services are held at the same time of day as the explosion occurred. It was the deadliest terrorist attack on American soil until the September 11 attacks, the chief conspirators, Timothy McVeigh and Terry Nichols, met in 1988 at Fort Benning during basic training for the U. S. Army. Michael Fortier, McVeighs accomplice, was his Army roommate, the three shared interests in survivalism. In March 1993, McVeigh visited the Waco site during the standoff, McVeigh later decided to bomb a federal building as a response to the raids. He initially intended only to destroy a building, but he later decided that his message would be better received if many people were killed in the bombing. He regarded the presence of law enforcement agencies, such as the Secret Service or the U. S. Marshals Service. McVeigh, a resident of Kingman, Arizona, considered targets in Missouri, Arizona, Texas, in December 1994, McVeigh and Fortier visited Oklahoma City to inspect McVeighs target, the Alfred P. Murrah Federal Building. The Murrah building had previously targeted in October 1983 by white supremacist group The Covenant, The Sword. The group had plotted to park a van or trailer in front of the Federal Building, after Snells appeal for murdering two people in unrelated cases was denied, he was executed the same day as the Murrah bombing. In addition, McVeigh believed that the space around the building would provide better photo opportunities for propaganda purposes
