Jail trustee Lloyd A. Miller, 33, of Alton apparently walked away from the jail at 7 a.m. on Dec. 21, when he took some boxes out to the trash, according to Lt. Mike Coldiron.
Miller was booked into the jail on Nov. 18 on Oregon and Howell county felony charges of resisting arrest, burglary, theft, forgery and possession of a controlled substance.
The jail has 55 beds. Usually, two inmates facing less-serious charges serve as trustees, and perform jobs such as cooking, laundry or cleaning. The jail now has one trustee since Miller's escape.
Miller is due in Oregon County Court on Jan. 3, 2012, for a disposition hearing regarding Oct. 25, 2010, charges of felony theft and second-degree burglary.
Miller also is set to appear in Howell County Court on Jan. 9, 2012, for sentencing for two felony forgery convictions.
Miller is described as being 5-feet, 11-inches tall, weighing 170 pounds and having a clean-shaven face and head.
Howell County authorities issued a warrant for Miller's arrest on Dec. 22, with bond set at $250,000.
Anyone with information on Miller's whereabouts is asked to call the Howell County Sheriff's Department at 417-256-2544.
