Investigators from the Crash Reconstruction Unit are looking for witnesses to a pedestrian accident that occurred last night. Shortly before 8:20, a 21 year old Somerville resident, who is also a Tufts University student, was struck by a car as he crossed Powder House Blvd at Packard Avenue. The victim was transported to Massachusetts General Hospital where he is in critical condition. The operator of the striking vehicle, also a Somerville resident, has cooperated with investigators.

Police believe that there was at least one person who was standing at the intersection at the time of the accident. There was also another vehicle traveling behind the accident vehicle. Investigators would like to speak to them and any other person who has information about this tragic event.

Anyone with information should call 617 625-1212.
