Suffolk County District Attorney Kevin Hayden is in the process of rolling out a new rapid indictment program aimed at moving the most serious gun cases through the courts quickly.

Hayden announced the program on Greater Boston Thursday, saying he's making two grand juries and two prosecutors available to review gun cases.

The program already resulted in 30 indictments in the last month, according to Hayden.

Hayden announced the program following the shooting of a student and teacher outside a Dorchester school Tuesday night. The investigation remains active, and the shooter was still at large the day after the shooting.

"This stuff is very personal. It touches close to home when we look at young kids in a school setting where they expect to be safe," Hayden said.

"When something like this happens at the hands of people from outside that community...it's terrible, it's terror, and it has an extraordinary impact on our community," he added.
