Clinnon Jeffery, also known as Clinton, was 60 when he disappeared from Springfield, Illinois, in early 2012. He is described as 5 feet 6 inches to 5 feet 8 inches tall, 150 to 170 pounds, with graying black hair and brown eyes. Distinctive features include an amputation of his left arm below the elbow and a few scars on his chest.

The last confirmed contact with Jeffery was on February 1, 2012; his family says communication stopped between the end of February and the beginning of March. He may have been traveling toward Kansas City when he vanished. No report was filed with the Springfield Police Department until August 5, 2012, and his case is logged in NamUs as MP17105.

There has been little public information about his movements after early February, and the delayed report narrowed opportunities for timely leads. If anyone saw Clinnon Jeffery in Springfield, en route to Kansas City, or afterward, please share what was seen or where he might have been headed.
