South Carolina prosecutor filed new charges in the case involving a man accused of killing nine people at a Charleston church.

According to The New York Post, prosecutor Scarlett Wilson said 21-year-old Dylan Roof had been indicted on three new charges of attempted murder on Tuesday. The state charges came from people who survived the attack on June 17.

Last month, Roof opened fire on a group of people attending Bible study at the Emmanuel African Methodist Church. Roof was charged with nine counts of murder for the amount of people he killed while he also faces a weapons charge.

It is not clear if federal authorities will pursue hate crime charges against the suspected white supremacist.

The indictment documents show that the three surviving victims were two women and a girl, according to Los Angeles Times. The documents also showed that Roof spent an hour in the Bible study session with parishioners before opening fire.

"Prior to leaving the Bible study room, he stood over a witness to be named later and uttered a racially inflammatory statement to the witness," the documents read.

There is no other information about the new charges as of yet. 

"While it is extremely important to me that I am open and transparent with the public about the legal proceedings and the continuing investigation into this matter, as a lawyer and prosecutor, I am subject to special rules limiting my ability to make public comments about pending cases and defendants in criminal matters," Wilson said.

The prosecutor emphasized that Roof is still innocent until proven guilty.

Roof wrote an online manifesto prior to the shooting regarding his white supremacist ideology.

"We have no skinheads, no real KKK, no one doing anything but talking on the internet," the manifesto stated. "Well someone has to have the bravery to take it to the real world, and I guess that has to be me."

The shooting case prompted people to revisit the long debate about keeping the Confederate flag up on state grounds.
