# Oklahoma City Bombing **Entity class:** Domestic terrorist attack **Date:** April 19, 1995 **Location:** Oklahoma City, Oklahoma **Maturity:** Developed ## Definition The **Oklahoma City bombing** was the truck-bomb attack on the [[wiki/Alfred P. Murrah Federal Building|Alfred P. Murrah Federal Building]] that killed 168 people and injured hundreds. The FBI's investigation was code-named OKBOMB. ## Response Architecture The FBI led the criminal investigation, with ATF and other agencies assisting. FEMA coordinated federal consequence management. The Department of Defense designated a defense coordinating officer; the Army Reserve, Army Corps of Engineers, and Oklahoma National Guard supplied personnel, engineering, command facilities, aviation, medical readiness, security, reconnaissance, transport, logistics, and other support. The case shows the difference between lead authority and capability. Domestic terrorism remained a civilian-led criminal matter while military infrastructure materially supported rescue, recovery, security, and investigation. The reviewed public record confirms Intelligence Community support but does not establish that Army Intelligence commanded the OKBOMB investigation; that stronger proposition remains unresolved pending specific tasking or command records. ## Relationships - **target:** [[wiki/Alfred P.
