The family of kidnapped former FBI agent Robert Levinson has released chilling photographs received in early 2011. The photos show Levinson, who disappeared in Iran while working as a private investigator in 2007, clad in an orange jumpsuit and holding signs with captions including, "I am here in Guantanamo. Do you know where it is?" and "This is the result of 30 years serving for USA." Iran denies knowing anything about the kidnapping but US officials suspect the country's intelligence service was involved, the AP reports.
Officials speaking under condition of anonymity say investigators have concluded that the photos and a video were sent by a professional intelligence service like Iran's Ministry of Intelligence and Security. American diplomats and the FBI have been working behind the scenes to find Levinson, but his wife, who believes he is still in Iran, says she decided to release the photographs because the US has not put enough pressure on Mahmoud Ahmadinejad's government. "There isn't any pressure on Iran to resolve this," she says. "It's been much too long." (Read more Robert Levinson stories.)
