CHARLESTON, SC (WCSC) - Dylann Roof's federal attorneys filed paperwork on Monday stating they will try to prove Roof was mentally ill during the shooting that took the lives of nine people at the Emanuel AME Church.
In court records released on Monday, attorneys say they will introduce expert evidence relating to a "mental disease or defect or any other mental condition" bearing on the issue of punishment.
Roof's federal trial is scheduled to begin in November.
He is facing the death penalty.
Roof faces 33 federal charges in the incident that left nine people dead and three injured at Emanuel AME Church in June 2015.
Jury selection for his federal trial is scheduled to start on Nov. 7.
Roof's attorneys say he will plead guilty to his state charges if the government stops pursuing the death penalty.
The suspect was indicted on 13 charges in state court.
His state trial is scheduled for Jan. 17, 2017.
