A Boston subway trolley driver investigators say was sending a text message when the car he was operating plowed into the back of another train has been indicted.
Aiden Quinn was indicted by a Suffolk County grand jury Wednesday on charges of grossly negligent operation of the Green Line train.
Nearly 50 people, including Quinn, were hurt when the trolley he was operating rear-ended another train between the Government Center and Park Street stations on May 8. The crash caused an estimated $9 million in equipment damage.
The Massachusetts Bay Transportation Authority fired the 24-year-old Quinn about a week after the accident.
He is scheduled to be arraigned in Suffolk Superior Court July 20.
Quinn's attorney did not immediately return a call for comment Wednesday.
