Family confirms Robert Levinson, former FBI agent, dies in Iranian custody

Levinson disappeared from Iran’s Kish Island on March 9, 2007. For years, U.S. officials would only say that Levinson, a meticulous FBI investigator credited with busting Russian and Italian mobsters, was working for a private firm on his trip.

In December 2013, The Associated Press revealed Levinson in fact had been on a mission for CIA analysts who had no authority to run spy operations. Levinson's family had received a $2.5 million annuity from the CIA in order to stop a lawsuit revealing details of his work, while the agency forced out three veteran analysts and disciplined seven others.

Rumors have circulated for years, with one account claiming he was locked up in a Tehran prison run by Iran’s paramilitary Revolutionary Guard and U.S. officials suggesting he may not be in Iran at all. Dawud Salahuddin, an American fugitive living in Iran who is wanted for the assassination of a former Iranian diplomat in Maryland in 1980, is the last known person to have seen Levinson before his disappearance.
