pictures, some of which appear to be taken after the scene also show the remains of a shredded black knapsack or backpack, all of which seem to be managed by authorities. they are sent out to agencies so everyone can compare notes. there is this photo as well from local affiliate wga showing a bag by a mailbox where the first bag went off at the finish line. the question tonight, was it one of the bombs? the fbi is analyzing it along with fragments of the pressure cooker. there is that and there is this. breaking news out of washington, letter to the senator testing positive both in the field and in the lab for the deadly poison lab. dana bash is going to be working her sources on that. she ll be joining us shortly. we ll also hear from the people w whose family members lost their lives. we know there was a chinese national, a grad student at boston university not far from
appeared to be the pipe bomb, the wires and a plastic food storage container containing nails. so the two law enforcement officers immediately moved the crowd down the hill, and as they were getting the crowd out of the way and further down below, the device detonated, killing one woman, and then later a journalist had a heart attack running to the scene. but the fact that a trained two trained bomb techs actually saw a look at that device under the lid of the knapsack and immediately went to work to get the people out of harm s way gave them a great indication of how it was set up, how it was put together even before it exploded. so that was huge. and the fbi was able to trace later, but it took months to track down the roofing nails that were used because they were able to determine what company made those nails, and then because of a unique glitch in the company s equipment, there was a batch made that had a slight deformity that made that
