You know an urgent plea for help finding whoever was responsible for the deadly terrorist attack in Boston.
The FBI now asking the public to come forward with photos videos anything.
They might have seen or heard.
The person who did this is someone's friend neighbor coworker or relative.
We are asking anyone who may have heard someone speak about the marathon.
Where the date of April 15.
In any -- been indicated that he or she may target the event to call us.
Someone knows who did this.
Former FBI special counterterrorism agent in New York John I think -- he joins us now to talk a little bit more about this near here in the lead FBI investigators say there in the case.
Someone knows who did best.
Begging people the public to come for what was whatever tips today may -- You know importance for them to see pictures information anything asking for the public's help what does that tell you about the state of their investigation.
You can never tell where the bureau are of the task force is in their investigation mean they're the best at what they do.
From this point forward there is nobody better than than what they do is for is digging through this massive puzzle.
Of investigative leads.
One thing that.
That you have to look at here is that there's two investigations going on there's one investigation that's going on from the point of that explosion forward.
And there's also investigation going on looking at how this actually happened.
The second investigation of how this actually happened ties in with.
To actually did it.
And that's where they're asking that the public for their assistance most people realize that they can be an integral part.
And a lot of the times nowadays with cellphones.
And there's witness is everywhere and a special event.
There there's there's our witnesses there.
We're constantly taking pictures can't you -- speak to that a little bit more how this happened to begin Wednesday.
We saw -- -- short time ago within the bomb sniffing dogs that are out there today than we know that that was also the case prior to.
That marathon -- errors -- how did these devices which were now being told.
Apparently were in -- a big large size duffel bags left there at the scene these two different locations where the bombs went off how did that happen.
Lets you question that's the million dollar question and having her -- -- special events in New York City for the FBR from many years.
And having been a seal prior -- coming to the FBI.
I'm skilled at looking at things from an -- defender point of view.
Don't really realize that they have that ability until they getting to a crisis situation.
But -- unfortunately the way a lot of these things unfold is there's a sweep.
Of an event and then.
There should be a walk down.
But because of pain at that point of the -- -- no one else is allowed -- it anymore grabs or anything to present I don't.
And unfortunately a lot of these situations you have our vendors.
Or you have hotels or you have ticket holders.
And they're allowed to come in there.
That's part of the whole process of a special event is -- people to be and then -- critical areas such as the finish line where there's just massive amounts of people.
-- any special that it doesn't matter if it's a marathon or if it's a concert or a yankees game.
If the -- when you're gonna have the most highly concentrated groups of people and we want to place blame at this point nine days ago when you know I had.
What -- point fingers what I'm looking at here though from -- attackers point of view is.
-- a unconventional warfare attacker.
Is always looking at the tactics that are used by law enforcement and -- awareness of the civilian population.
And then they.
It just their tactics to maneuver around those things.
So -- perhaps knew that after this lockdown they can still get something and I'm sure it was awesome that's a little bit about the pictures that have now been released in terms of the bombs themselves.
The fact that a pressure cooker apparently was used in look at these pictures -- you can see some sort of numbers.
More than that are still intact so hopefully that can perhaps be a serial number they can track where was -- but you also say.
Even more importantly because there's all this information about how you can use a pressure -- are available online so anyone can see how to do it time maybe the triggering device that was used.
It it could be I think more often than not and these investigations if you look back historically.
Is a big break in this puzzle and -- you got to think about this puzzle.
Is being massive amounts of pieces.
Several different pictures yes so once they find something that they can hone in on.
They're they're able to start really picking more specific pieces.
And more often denied what they find that he is a break is a serial number receipt which is.
You know -- for a rental car or in this case you know for whatever.
Type of device they use.
-- they can also look at the specifics of how those things -- -- who uses.
You know a triggering device.
Verses remote device those are all tell -- signs that they can look into a footprint ST -- may have done it that's correct and more often not the serial numbers those types of things.
Tom can really lead them to to a lot in these investigators -- can't tell -- enough.
They're incredible what they -- I thank you so much for joining us I'm sure we'll having -- sure we appreciate the insight.
