According to CNN, the MIT shooters were the marathon bombers. One of them is dead, and there's a citywide manhunt for the other. MIT is currently on lockdown - classes are cancelled, employees were told to stay home, and students were told to stay in their residences. Actually, the whole area is pretty much on lockdown - public transport isn't running, and people have been told to stay home and not answer the door for anyone but authorities.
Unbelievable. Just ... unbelievable.
