Prosecutors in South Carolina said Tuesday that Dylann Roof, the man accused of gunning down nine people inside a Charleston church, has been indicted for the shooting spree.

Roof, 21, was already charged with nine counts of murder following the killings inside Emanuel AME Church last month. Scarlett A. Wilson, the prosecutor for Charleston County, said that her office also presented three attempted murder charges to the grand jury, one for each of the three people who lived through the massacre.

The grand jury indicted Roof on nine murder charges, three attempted murder charges and one count of possessing a weapon during a violent crime.

Wilson did not say anything about the possible punishment Roof may face if he is convicted. She has previously said she had made no decision about whether to seek the death penalty, something she said would only be decided after discussions with families of the victims. South Carolina Gov. Nikki Haley (R) has called for Roof to face the death penalty.

Roof has made only one public appearance since being booked at a Charleston County detention center. The 21-year-old appeared in a video feed at his bond hearing last month, his face remaining impassive as relatives of people slain in the church massacre stood to offer him forgiveness and say they were praying for his soul.

There are no other court hearings scheduled in Roof’s case, Wilson said.

While Wilson said in a statement that she cannot comment publicly on the case, she added that her office has been in constant contact with local police as well as state and federal investigators. Wilson also praised Judge J.C. Nicholson Jr., who was assigned the criminal case by the state Supreme Court.

The Justice Department is also investigating the shooting that took place last month. The federal government is likely to bring hate-crime charges against Roof, according to a law enforcement official.
