Dylann Roof pleads guilty to charges in church massacre

Washington : Dylann Roof, who shot nine people to death in a black church in Charleston, South Carolina, pleaded guilty on Monday to state charges in the killings, a media report said.

Roof was sentenced to death in January by a federal jury for the June 2015 massacre at the Emanuel African Methodist Episcopal Church, CNN reported.

Roof became the 63rd person on federal death row. He is expected to be transferred to a facility in Terre Haute, Indiana, the report said.

Roof told investigators in a recorded interview that he committed the crime because "black people are killing white people every day."

At the federal trial, Assistant US Attorney Jay Richardson said the admitted white supremacist scouted out his target multiple times, and sat with the church group in a Bible study class for 40 minutes before shooting. 

Richardson said Roof pulled the trigger "more than 75 times ... reloading seven times" as he stood over his victims, shooting them repeatedly.
