ABC’s Pierre Thomas ‘Everything Is on the Table’ in Investigation into NYC Explosion

THOMAS: "Everything is on the table. There’s a great sense of urgency. You have the U.N. General Assembly going on. They need to know who did this and they need to know now. The key this morning, my sources are telling me, are forensics. When you have a bomb or an explosive detonate, it doesn’t get completely obliterated. So they’re able to get parts of it. So they’ll try to put those parts back together, look for fingerprints. The same thing with the pressure cooker. Will they find any print — fingerprints on that? Again, they still don’t know if that is an actual bomb yet, but they are checking this morning."
