The Justice Department intends to seek the death penalty against Dylann Roof, the man charged with killing nine black parishioners last year in a church in Charleston, S.C., Attorney General Loretta Lynch said Tuesday.
"The nature of the alleged crime and the resulting harm compelled this decision," Lynch said in a brief statement that said the department had considered "all relevant factual and legal issues."
Roof is awaiting trial on federal hate crime charges in connection with the June 17 shooting at Emanuel AME Church, which contributed to a national conversation about race relations and also led to the removal of a Confederate battle flag from the South Carolina Statehouse.
Roof is also charged with nine counts of murder in state court, and South Carolina prosecutors have already announced plans to seek the death penalty when he stands trial next year. Solicitor Scarlett Wilson has said she wants her case to be tried first.
Roof, who is white, appeared in photos waving Confederate battle flags and burning or desecrating U.S. flags, and purportedly wrote of fomenting racial violence. Survivors told police that he hurled racial insults during the attack. He was arrested a day after the shootings when a motorist spotted his Confederate license plate.
Federal prosecutors charged Roof with hate crimes one month after the shooting, saying he was motivated by racial hatred and a desire to commit a "notorious attack" when he opened fire inside the church.
"To carry out these twin goals of fanning racial flames and exacting revenge, Roof further decided to seek out and murder African-Americans because of their race," Lynch said at the time.
Though the Justice Department says it's committed to seeking the death penalty, federal executions are exceedingly rare. The last time a federal defendant was put to death was in 2003. And President Barack Obama has said he's "deeply concerned" about the death penalty's implementation.
Roof's attorneys in the federal case have said their client would be willing to plead guilty if the death penalty were not on the table. Joey Meek, a friend with whom Roof spent time in the days before the shootings, pleaded guilty last month to lying to federal authorities. He has agreed to help with the prosecution against Roof.
