From the comments, "Roupen Bastajian, a 35-year-old state trooper from Smithfield, R.I., had just finished the race when they put the heat blanket wrap on him and he heard the first blast.
"I started running toward the blast. And there were people all over the floor," he said. "We started grabbing tourniquets and started tying legs. A lot of people amputated. ... At least 25 to 30 people have at least one leg missing, or an ankle missing, or two legs missing."
Whoever did this is getting their terror/propaganda effect - 30 people with lost limbs will have a much higher media impact than 300 dead in, say, an airliner bombing.
