Oklahoma authorities are searching for an escapee from the William S. Key prison in Fort Supply.

Officials say 42-year-old Floyd Miller was noticed missing at about 7:30 a.m. Sunday. Prison records show Miller is serving a 15-year sentence for producing methamphetamine.

Miller has a previous extortion conviction and arrived at the prison in February.

The facility doesn’t have a perimeter fence. Officials say Miller could have walked away or gotten into a waiting vehicle.

Miller is 5 feet 8 inches tall, 154 pounds with red hair and brown eyes.

Officials say anyone sighting him should call police.
