Two years after a hostage video and photographs of retired FBI agent Robert Levinson raised the possibility that the missing American was being held by terrorists, U.S. officials now see the government of Iran behind the images, intelligence officials told The Associated Press.

Levinson, a private investigator, disappeared in 2007 on the Iranian island of Kish. The Iranian government has repeatedly denied knowing anything about his disappearance, and the disturbing video and photos that Levinson’s family received in late 2010 and early 2011 seemed to give credence to the idea. …

Two years later, with the investigation stalled, the consensus now among some U.S. officials involved in the case is that despite years of denials, Iran’s intelligence service was almost certainly behind the 54-second video and five photographs of Levinson that were emailed anonymously to his family. The tradecraft used to send those items was too good, indicating professional spies were behind them, the officials said, speaking on the condition of anonymity because they weren’t authorized to talk publicly. While everything dealing with Iran is murky, their conclusion is based on the U.S. government’s best intelligence analysis.
