IEDs or Improvised Explosive Devices are makeshift bombs commonly constructed by terrorists and other extremists to inflict casualties on enemy forces and civilians. Examples of IEDs used in terrorist attacks in the United States include both the Boston Marathon Bombing* and the Oklahoma City Bombing on the Alfred P. Murrah Federal Building in 1995. Unsuccessful bomb builders have been identified or captured and their explosive devices were impounded. In such cases, it is beneficial to have evidence linking the bomb with its maker. Latent fingerprint evidence is one such method for making this link.
This 24-hour Processing Improvised Explosive Devices for Fingerprints course will instruct the student in the proper methodologies to be used in processing explosive devices for latent fingerprint evidence. As part of the instruction, the students will learn about IEDs, how they are constructed, and the safest ways to handle them.
Due to the sensitive nature of the course content, this course is only open to bona fide members of a law enforcement agency, the military, and credentialed government contractors.
Upon completion of this training the student will:
Describe the design and construction of IEDs
Demonstrate safe handling of IED evidence
Demonstrate the ability to process IEDs for fingerprints using various non-destructive, chemical and mechanical methods
Describe the intelligence value of fingerprints on IEDs and how to interpret this evidence
