one in a black hat, one in a white hat. suspect one and two, they re being called. susan candiotti s source telling her that investigators are focusing on both the type of hats and the behavior of the apparent confidence of the two men wearing those hats and the behavior, according to susan s source, of one of them after the bombs went off. as we look at additional images, we isolated the video and should tell you about joe johns reporting as well. his sources are inclined to believe the two bombs were detonated by remote control, not timers as earlier believed. remember, earlier days ago when sources were saying timers, they said it was likely timers, they re not absolutely certain, so again, getting more information from different sources. a reminder, anyone who has any information about who these suspects are is being asked to call the fbi. the number is 800-call fbi. 800-call fbi. joining me now is jeff beaty, former fbi agent and
0 we ll see you back here live at 11:00 from boston as our coverage of the new fbi breakthrough continues here on cnn. also, the coverage of the horrific explosion in west texas which has claimed more lives than anyone thought. anderson cooper is there in west texas and ac 360 begins right now. good evening, everyone. there is big breaking news in boston and utterly horrific breaking news right here in this small texas town of west. search, rescue, recovery and damage assessment from the blast that rocked a fertilizer plant here just north of waco. it registered as a small earthquake, flattening entire buildings, burying people alive, killing them in some cases where they stood. claiming the lives we re now learning of many volunteers who rushed to help. this story is changing even as i stand here and we re going to bring you all the latest on it throughout the evening tonight. we ll be back on at 10:00 again for another update. we begin though on the story out of boston which just
apprehend them. armed and dangerous. like timothy mcveigh. but then we came to the backpacks i think that we were talking about earlier. let me just we re going to talk about that. we re going to put up a split screen. they talked about suspect number one with the black backpack. we want to put that next to the picture that everyone had seen before of the black backpack when they seen it exploded when earlier this week.had released - now, jeff, you that i is very important. here it is. we re looking at that. exactly. and, you know tshgsz close. it doesn t exactly seem to be a match. and so one of the things that people need to be aware of and the public needs to be aware of when you re at a location is the possibility, heck, even shoplifters use this technique. it is a trojan horse. you could come into a place and you are carrying a backpack. we have one here. it has a number two on it. it s easy enough for you to take out the actual device that may
the finish line, not so much the second one that was further away. as can you see right there, erin, i m stopping it so you can get a good look at it, you can see this pock pack is really much more of a light gray or white color, whereas the one up ahead here, this is the one that is black. so erin, it s just context. it doesn t necessarily tell us a whole lot but you re absolutely right. when you say you just want to watch it and watch it again, this is what the fbi wants people to do. watch this and watch this and look at the individual pictures of these people and see if somehow in doing that, you can spot somebody or something that will help them make an arrest. erin? tom foreman, thank you. i want to bring in jeff smith, the associate director of the national center for media forensics, expert at analyzing video and counterterrorism deputy is back. good to have both of you. let me start with you, jeff smith. when you look at this video, let me ask you one of the things we ve tal
