Gerald Alan Duncan, 43, pleaded guilty on Monday to second-degree murder and armed criminal action for the shooting death of James Pruitt on July 5.
In a plea agreement, Duncan received a life sentence with parole and 10 years for armed criminal action. He is required to serve a minimum of 251/2 years to be eligible for parole, said Kevin Crane, Boone County prosecuting attorney.
Duncan was scheduled to be tried in April on a first-degree murder charge and an armed criminal action charge.
A jury in February found Lucille Duncan, Gerald Duncan’s sister, guilty of first-degree murder and armed criminal action.
“He assumed his trial would not go any better than hers,” said Jo Ann Duncan, Gerald and Lucille Duncan’s mother.
Lucille Duncan is scheduled to be sentenced April 5. A first-degree murder conviction is punishable by execution or life without parole. Crane has said he does not plan to seek the death penalty.
