i to bring in bridget murphy, she is with the "associated press" and joins us on the phone. i understand, bridget, you're on lockdown after the explosion? tell us where you are, what you saw, what you heard? >> yes. apologies if it's a little loud here or if i miss one of your questions. i'm actually in the main press room. we had been collecting quotes from some of the winners a short bit earlier. and we were sitting typing our stories on deadline and we heard what was sounded like at least two booms. we just kind of looked at each other, was that thunder, what was that? some of my colleagues were outside. at least one was able to get out of the building and talk to some of the eyewitnesss and survivors. so we don't have any totals yet on injuries, but my colleague, jay lindsey, spoke to a rhode island state trooper who just crossed the finish line about two minutes earlier. he described seeing at least 25 to 30 people with limbs missing. either one leg, an ankle missing, or even two legs missing and he said people were just grabbing whatever they could and tieing off people
