Investigators are now trying to question one of the three drivers involved in the accident. Officers saw him speeding down Route 109 moments before the crash happened as they were conducting an unrelated traffic stop. Aerial footage from the NBC Sky Ranger showed at least one vehicle overturned on its roof. Further down the road, two more vehicles could be seen with heavy damage. Tobia was driving a Chevy, which was heavily damaged in the accident. The driver of a Kia was hurt. And the man behind the wheel of the Jeep is at Tufts Hospital. Police say they've been unable to speak with him because of his condition.
