The federal building was designed by architect Wendell Locke of Locke, Wright and Associates 1, and constructed using reinforced concrete in 1977 at a cost of $14.5 million. The building was named for federal judge Alfred P. Murrah, an Oklahoma native and opened on March 2, 1977.
The remains of the building were imploded a month after the attack, and the Oklahoma City National Memorial was built on the site. The Federal government began construction of a new building to replace the Murrah Building in late 2000. This new building was placed just to the north of where the Murrah Building had been located, and incorporated a number of security measures implemented after the bombing of the Murrah Building.4
At 9:02 A.M. on April 19, 1995, a Ryder rental truck bomb containing approximately 5,000 pounds (2,300 kg) of ammonium nitrate fertilizer, nitromethane, and diesel fuel was detonated in front of the Alfred P. Murrah Federal Building, destroying a third of the building and causing severe damage to several other buildings located nearby. During McVeigh's trial, a witness testified that McVeigh claimed to have specifically arranged the explosives in order to form a shaped charge.5 As a result of the massive explosion, 168 people were killed and over 800 others were injured.6 It was the largest terrorist attack on American soil in history before the September 11 attacks. Timothy McVeigh would later be found guilty of the attack and sentenced to death.
Demolition
Rescue and recovery efforts were concluded at 11:50 p.m. on May 4, with the bodies of all but three victims recovered.7 For safety reasons, the building was to be demolished shortly afterward. However, McVeigh's attorney, Stephen Jones, called for a motion to delay the demolition until the defense team could examine the site in preparation for the trial.8 More than a month after the bombing, at 7:01 a.m. on May 23, the Murrah Federal building was demolished.7 The final three bodies, those of two credit union employees and a customer, were recovered.9 For several days after the building's demolition, trucks hauled 800 tons of debris a day away from the site. Some of the debris was used as evidence in the conspirators' trials, incorporated into parts of memorials, donated to local schools, and sold to raise funds for relief efforts.8
