Department of Corrections spokesman Jerry Massie says 27-year-old Kenneth Hammick II was last seen during a head count Thursday morning.
Hammick is described as a white male, 5-foot-11, 154 pounds with brown hair and hazel colored eyes.

He was set to be released in August, 2014.
The DOC says Hammick is considered armed and dangerous.
