FORT MADISON, IOWA -- The Lee County sheriff reports that a citizen in Missouri spotted a 42-year-old man who escaped from a prison work detail Monday afternoon.

“He stopped down in Missouri somewhere and gave a citizen $20 for some gas,” Sheriff Jim Scholl said. “He's traveling southbound.”

Steven Adcock was on a work detail at the Oakland Cemetery about noon when he fled and stole a truck.

A resident in Clark County, Mo. reported the sheriff's office that a man matching Adcock's description was driving a blue 2002 Dodge Ram Quad Cab truck with an Iowa license plate number 558 XZM.

He is described as a balding white male with remnants of black hair. He has brown eyes, weighs 240 pounds and is 5 feet 10 inches tall.

Perhaps the best way to identify Adcock is by his tattoos. He has a skull and "SWP" tattoo on his left forearm, a tattoo of a "gun with a lady" under his right arm, the tattoo of a face with the words "Pamela Jo" on his right shoulder and on his chest he has the word "skins" and a swastika symbol.

Adcock was admitted to John Bennett Correctional Center at the Iowa State Penitentiary in Fort Madison on January 24, 2011 and was serving a 16-year sentence for habitual burglary charges in numerous counties and drug possession.

If you have any information about Adcock's whereabouts, please contact the Keokuk Police Department at (319) 524-3132 or the Lee County Sheriff's Department at (319) 372-1152.
