Authorities say an inmate with a history of escaping from work release has done it again.

Roger Romero Clayton, 36, an inmate at the Davenport Residential Re-entry Center, was at his job site Friday when he left and didn’t return, Jim Wayne, regional director Iowa Department of Corrections, said Tuesday.

Clayton worked at the Interstate 80 truck wash in Walcott, Iowa. Iowa inmates can finish out their prison sentences in a work release program.

Clayton was sentenced in 2006 to 20 years in prison after a jury found him guilty of going armed with intent and intimidation with a dangerous weapon. He first was released to a halfway house in February 2012. After an escape attempt, he returned to prison in April 2012, Wayne said.

He was living back at the halfway house at 605 N. Main St., Davenport, when he escaped Friday from his job and was still on escape status as of 1 p.m. Tuesday.

Wayne said Clayton is not an “immediate threat” but still considered dangerous.

“Obviously, he wasn’t in prison for being a good boy,” Wayne said.
