In the photographs , retired FBI agent Bob Levinson stares straight at the camera and holds signs , his hands shackled . Reflecting a poor grasp of English , one note reads : `` WHY YOU CAN NOT HELP ME . '' Another states : `` 4th YEAR ... You Cant or you Dont want ... ? '' On Tuesday , Levinson 's family released the images , showing the former agent in an orange jumpsuit with long , unkempt hair . A family spokesman told CNN the photographs were received in April 2011 . Asked why the family is releasing the images now , more than 18 months later , the spokesman said : `` The family is anxious that not enough is being done . There is frustration with the lack of progress on the case . '' Wife of missing American pleads for help from Iran 's president . `` We hope it will get things moving , '' the spokesman said . Levinson was last seen on Iran 's Kish Island in March 2007 . According to his family , Levinson was working as a private investigator looking into cigarette smuggling and disappeared during a business trip there . The family and the U.S. State Department have repeatedly denied he was working for the government and have urged Tehran to find him . `` I feel Iran needs to resolve this now . It 's been six years , '' Christine Levinson , the missing man 's wife , told CNN . She said her husband will likely miss another family milestone this year ; their daughter is getting married in February . Family asks Ahmadinejad for help . `` He looks healthy , but I 'm concerned about his health . I understand that he 's being seen by a doctor three times a week and , if true , that 's not good , '' she said , describing the photographs as disturbing . Levinson suffers from diabetes and appears to have lost 50 to 60 pounds since his capture . U.S. officials believe Levinson , now 64 , is being held hostage somewhere in southwest Asia . While it 's unclear who is holding him , a source with knowledge of the case said based on the evidence , there is every reason to believe that Levinson is alive and well . In 2010 , Levinson 's captors sent a `` proof of life '' videotape and photographs of him to his family . Those images were released to the public in 2011 . The FBI has offered a $ 1 million reward for information leading to Levinson 's safe return . Federal authorities still hunting for Levinson .
