Investigators are tracking down some two-thousand leads this morning after the twin explosions that occurred on Monday at the Boston Marathon. Officials are also poring over chilling photos showing the remnants of one of the detonated devices. Some of the images show wires, a battery and bits of what appears to be a circuit board. In addition, the FBI is now saying the second bomb was also in some type of metal container. This morning former Senior NCIS Official Robert McFadden weighs in on new investigation details regarding the Boston Marathon bombings.
The information to build an improvised explosive device is “readily available in open sources for books and the internet,” says McFadden.
Currently crime scene processing and forensic technicians are making the initial assessments from components found at the scene and conducting chemical tests to match the pieces with past bombs says McFadden.
The former Senior NCIS Official says secondary fragmentation elements such as “BBs or small nails or other components that would have been inside the pressurized device” may also match up with other past components.
McFadden says however that it is important to keep in mind that because “there’s such a broad spectrum of different individuals and groups that use this kind of simple device” that it could result in “quite some time for detective work.”
