The attack was carried out by Timothy McVeigh, a former Army soldier bent on revenge against the U.S. Federal Government for the siege against the Branch Davidian compound in Waco, Texas, exactly two years earlier.Roberto Schmidt / AFP / Getty Images
Vigil
Mourners gather at a memorial service for the victims of the attack. President Bill Clinton, after declaring a national day of mourning, said to the people of Oklahoma City, "You will overcome this moment of grief and horror. You will rebuild, and we will be with you until the work is done."Bob E. Daemmrich / Corbis

John Doe No. 1
Timothy McVeigh, above center, was arrested on weapons charges — less than 90 minutes after the attack — after being pulled over for driving without a license plate. He was later charged, convicted and sentenced to death in federal court. "I didn't define the rules of engagement in this conflict," McVeigh said in an interview. "The rules, if not written down, are defined by the aggressor. It was brutal, no holds barred. Women and kids were killed at Waco and Ruby Ridge. You put back in [the government's] faces exactly what they're giving out."Bob Daemmerich / AFP / Getty
Beyond Repair
On May 23, 1995, the Alfred P. Murrah Federal Building was demolished, and the last three missing victims' bodies were recovered. The site is now home to the Oklahoma City National Memorial and Museum, which honors the victims.Greg Smith / Corbis
