Morning doctors are working -- -- more than a 144 people injured in yesterday's bombing in Boston most of them with injuries from the waist.
It was some sort of shrapnel ball bearings -- -- means things like that -- today investigators need to figure out what kind of bomb could create that kind of explosion.
Mike White is a director of explosives training at.
MSA security and a former commanding officer in the NYPD bomb -- -- moratorium morning to.
You know what we're gonna put up.
Some of the images we have and Mike if you would just to -- play by play tell us what you can tell just by looking at some of these pictures of the explosion.
-- now -- all right let's go ahead and does start one of The Who got a number of them here is right at the finish line.
-- of of course the first thing you see is the color -- the -- spoke -- direction and it's going.
And -- he really tell from that is something exploded all right so initially there were reports of what the possibilities for everything from -- propane gas tank to -- accidental.
And after the sec going off every sort of figured out well maybe this wasn't tested -- that -- talked about the color of the smoke the smoke is white.
Yes it is what does that mean well anybody in the explosives and feel will be able to tell -- -- certain explosives.
We'll give you different -- plumes of smoke.
So if this smokeless gunpowder me well I've heard this little things being -- around and numerous reports in the media and other places someone I'd really like to do is not put.
Woman into one that's for sure they would step list but what you see from the when I've termed small explosion and that's exactly what it was.

-- -- such a high population density right there in the small improvised explosive device had a tremendous tremendous damage to the people right.
It we noticed that you know it's a little white -- you -- just kind of a cloud of smoke goes over but in the initial explosion it looks like the plume kinda goes straight up.
What does it what does that tell you it was any explosion you gonna have a 360 degree.
Push heave from the scene of the explosion.
So the fact that you have building there some of the blast of course when he and put the the plume traditionally he's going to come up by effort -- a mushroom cloud not quite.
Yet -- you see when the smoke is the thing that's interesting to look at his.
The lack of damage that the -- -- line -- -- -- street -- -- the barricades are intact.
The banners are intact the flags are intact.
The one -- they keep showing if you look just a few minutes into -- a few seconds and doing.
-- see that there was a yellow balloon now sort of floating away incidentally wasn't damaged and -- right nearby people down at a lower.
I've trajectory or -- horrific -- they were indeed all right -- what we thank you very much for your rockets.
