Tonight FBI bomb experts trying to do what might -- the -- -- impossible they're trying to piece together the small bomb fragments.
Tom Thurman is a former chief of the FBI bomb data center he joins us good evening -- Good evening and good evening tell you tell me how -- the pieces at the FBI are picking up on that crime scene.
-- and it has the the whole variety of pieces that we we've certainly seen in in the media in the photographs of actually fairly large pieces all folks again what what what appears to be.
A pressure cooker and as -- Most bombings or explosions like this we're gonna have very very small even some help -- -- of evidence that.
Our crime scene investigators or out on the scene.
Securing the throughout the area to find these very small pieces even.
All on the street imbedded in the walls.
All ceiling or rooftops I'm sure that they're out.
-- -- -- The roofs the better areas who are -- ledges.
And in this area and actually probably good distance away from the scene of the two explosions.
Why do you think the FBI have been in and there's an all the investigation all the pieces but in particular the switch.
That was used to cause the -- explored what does -- that that particular.
Item that they want and why.
Any explosive device.
Knowing this -- -- explosive device has two basic components -- the explosive which we we've seen explode.
And a mechanism to calls that saw explosive to explode.
Assuming and in this case that we held a panel what couples fusing system.
There has to be some type of a switch the colts the bomb -- essentially turn all.
All of that that switch can be a multitude of different things but.
If it's highly suggest -- and it's it's and I mean suggested at this point that.
It's some type of -- I've timing mechanism home one -- or possibly.
A remote control -- Device and looking at the that circuit board of those components can help.
The the FBI and identify specifically.
What top of a -- Switch that they health and that that will be done that so the FBI academy or the laboratory at Quantico Virginia.
I guess gonna turn -- rebuild I realize that did about a self you know it distorts and and and when exposes the starts -- -- but the their -- almost try to reassemble that bomb.
Well if it's it is reassembled them and into different -- one.
Is a forensic laboratory report that will go in to specific details.
How all the evidence examiner at the -- Determined that leave the blast logically exploded and the way that they come to that conclusion.
Is looking at all of these components that have been recovered.
It -- -- -- city.
And at at that point they may very well decide to say hey let's go out and purchase.
Various items that we're seeing here.
And make -- a real three dimensional model that this is exactly what it looked like.
And it may very well put it together to see if not actually explode.
But how well that the fusing system would work and -- based -- components that they recovered and their theoretical approach to it.
Time thank you very much -- Well thank you very much credits.
