Russell Lee Wood Jr. pleaded guilty to first-degree manslaughter last month, and he has been sentenced to 18 years in prison for that crime.
Wood, 51, of 7765 St. Joe Road in Finley, was indicted for murder after he shot his mother, Ida Wood, in June of 2006.
Wood pleaded guilty to the manslaughter charge with a note that he was mentally ill.
Marion Circuit Judge Doughlas George sentenced Wood to 18 years at the Kentucky State Reformatory. Wood will be sent to the nursing wing of the prison because of his physical and mental condition, George wrote.
