BELLEFONTAINE, Ohio (AP) -- Deputies in central Ohio are trying to track down an inmate they say walked away from a jail garden.

They say Joseph Knox left the Logan County jail complex northwest of Columbus Tuesday morning and hasn't been seen since.

WBNS-TV ( http://bit.ly/OuI5hw ) reports that Knox began his sentence for contempt charges at the jail July 19 and was expected to be released on Oct. 22. Investigators said that Knox also has a warrant for contempt of court out of another Ohio county.
