On January 25, 1993, outside the United States Central Intelligence Agency (CIA) headquarters campus in Langley, Virginia, Pakistani national Mir Qazi (also spelled as Kasi or Kansi) killed two CIA employees in their cars as they were waiting at a stoplight and wounded three others.

Qazi fled the country and was placed on the FBI Ten Most Wanted Fugitives list, sparking a four-year international manhunt. He was captured by a joint FBI-CIA/ISI task force in Pakistan in 1997 and rendered to the US to stand trial. He admitted shooting the victims, was found guilty of capital and first-degree murder, and was executed by lethal injection in 2002.
