Robert Crimo, the man accused of shooting into a crowd watching a Chicago-area Independence Day parade, was indicted by a grand jury on 117 counts, including 21 counts of first-degree murder, the state's attorney's office said on Wednesday, according to Reuters.
Crimo, 21, has been held without bail since he was arrested after the shooting at the July Fourth celebration in Highland Park that left seven people dead and more than three dozen injured. Four of the seven who were murdered in the shooting were Jewish.
He is set to appear in court on August 3 for his arraignment, Lake County State's Attorney's Office said in a statement on Wednesday.
Under the US legal system, a prosecutor can convene a panel of citizens, or grand jury, that has the power to decide whether there is sufficient evidence to bring a defendant to trial.
If convicted on the murder charges, he would face a mandatory sentence of life in prison without the possibility of parole, Eric Reinhart, the state's attorney for Lake County, said the day after the shooting.
Prosecutors have said Crimo had planned the attack for weeks before climbing to a rooftop and firing more than 70 rounds at parade spectators. He then made his getaway dressed in women's clothing and makeup to cover his facial tattoos, they said.
Officials also said that Crimo was considering a second mass shooting, indicating that after the first attack he drove his mother’s car to Madison, Wisconsin for that purpose.
