DES MOINES — A former Rock Island man will stay in an Iowa prison for killing a Milan woman in 1991.

Harry Sisco, 78, sought a commutation of his life sentence in the death of Audrey “Elaine” St. Clair, but Gov. Terry Branstad announced Friday that he has denied the application. Sisco is imprisoned at the Anamosa State Penitentiary.

Sisco was convicted of killing St. Clair on April 2, 1991, in the Quad-Cities, wrapping her body in garbage bags and dumping it in rural Muscatine County.

During an Iowa Parole Board hearing last year on his commutation request, Sisco told the board that he was “good friends” with St. Clair and described the killing as an accident.

Six people spoke at the hearing, urging the Parole Board to reject Sisco’s request. Sisco was the only person who spoke in favor of lessening his sentence.

The board deliberated just shy of eight seconds before unanimously voting against recommending that Sisco’s sentence be commuted. It was the same recommendation that Sisco’s caseworker at the Iowa Department of Corrections made.
