An inmate walked away Saturday from a minimum-security facility outside the walls of Folsom's California State Prison-Sacramento. At approximately 9 p.m. inmate Robert Ivan Micheletti was found missing from his bunk in a dormitory setting. Micheletti, 42, was admitted June 3 on a drug-possession conviction. "It was basically a walk-away," said Lt. Judy Loer, prison information officer. "The dorms are outside the electric-fence, secured perimeter, to house minimum-security inmates." Micheletti is described as being a white man, 5 feet 7 inches tall and weighing approximately 165 pounds, with brown eyes and brown hair. Micheletti may have shaven his head and may have a dark beard.
