CHARLESTON, SC. — The federal death penalty trial begins Monday for admitted Charleston church shooter Dylann Roof.

Roof admitted to opening fire during a bible study at Mother Emanuel in June 2015 where nine people died including state senator reverend Clementa Pinckney.

Jury selection began in the case in October. Seven hundred forty-seven potential jurors filled out questionnaires and 512 people remain in the pool.

The process to narrow them down to the final jury will begin November 7.
