BOSTON — The MBTA driver who crashed his trolley into another train late last year, injuring 17 riders, was using his cellphone during the collision and had brought a loaded gun onboard, The Boston Globe reports.
In an MBTA Transit Police affidavit filed in Dorchester District Court, investigators said the driver, Leroy H. Mattison, told authorities he reached into his backpack to “take a quick peek” at his phone shortly before the Dec. 29 crash and attempted to delete a posting he had left the night before on the website Reddit.com.
