The FBI announced a reward of up to $1,000,000 for information leading to the safe location, recovery and return of Levinson, who disappeared from Kish Island, Iran, five years ago on March 9, 2007. For years the U.S. has publicly described him as a private citizen who was traveling on private business. However, an Associated Press investigation reveals that Levinson was working for the CIA. There has been no hint of Levinson's whereabouts since his family received proof-of-life photos and a video in late 2010 and early 2011. (AP Photo/Manuel Balce Ceneta)
