Disappearance of Robert Levinson
Robert Alan Levinson (March 10, 1948 – presumed deceased before March 25, 2020) was an American former Drug Enforcement Administration (1970–1976) and Federal Bureau of Investigation (1976–1998) agent who disappeared on March 9, 2007, in Kish Island, Iran, while on a mission for the Central Intelligence Agency (1998–2007). Levinson's family received a $2.5 million annuity from the CIA in order to stop a lawsuit revealing details of his work in Iran and to forestall any revelation of details regarding the arrangement between Levinson and the agency.
