Timothy James McVeigh (April 23, 1968 – June 11, 2001) was an American domestic terrorist who masterminded and perpetrated the Oklahoma City bombing on April 19, 1995. The bombing itself killed 167 or 168 people (including 19 children), injured 684 people, and destroyed one-third of the Alfred P. Murrah Federal Building. A rescue worker was killed after the bombing when debris struck her head, bringing the total to 168–169 killed. It remains the deadliest act of domestic terrorism in U.S. history.
A Gulf War veteran, McVeigh became radicalized by antigovernment beliefs. He sought revenge against the United States federal government for the 1993 Waco siege, as well as the 1992 Ruby Ridge incident. McVeigh expressed particular disapproval of federal agencies such as the Bureau of Alcohol, Tobacco, and Firearms (ATF) and the Federal Bureau of Investigation (FBI) for their handling of issues regarding private citizens. He hoped to inspire a revolution against the federal government, and he defended the bombing as a legitimate tactic against what he saw as a tyrannical government.
