(NEWSER) – The family of kidnapped former FBI agentRobert 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.
