Howell County authorities were busy Jan. 3 investigating the Jan. 2 homicide of a West Plains former business owner, but said no further leads regarding Miller have been revealed.
Miller, 33, of Alton, was assigned as a trustee at the Howell County Jail in November, and apparently "walked away" from the 55-bed facility on Dec. 21, 2011, through an unlocked exercise yard door.
Howell County Sheriff Mike Shannon said a jailer unlocked the door so Miller could take out bags of trash.
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 usually has two inmates facing less-serious charges serve as trustees, performing jobs such as cooking, laundry or cleaning.
Oregon County Jail does not have a trustee program.
Miller was due in Oregon County Court on Jan. 3 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 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.
