Summary

Arson and explosion investigations are unique in that they both require a close working relationship with fire personnel in practically every instance, if the investigation is to be successful. The crime scene specialist must acknowledge the existence of this joint effort and to be able to function in a manner that indicates a spirit of co-operation and professionalism.

Additionally, both of these crimes require a limited knowledge of the mechanics of each in order for the crime scene specialist to be successful in his/her endeavours. Both arson and explosion crimes involve complex chemical reactions that can be influenced by the actions of the suspect (s) before and during the event. Numerous

types of trace evidence can be located at the scene of these crimes; however the crime scene specialist must be first familiar with the mechanics of each event and the potential evidence that can exist.

The goal of this lesson is to provide participants with an introduction to crime scenes containing evidence of arson or explosions. Participants will learn what physical evidence can be found at these scenes and used to identify the origin of the fire or explosion, as well as evidence that can be used to help identify the suspect’s.

At the conclusion of this lesson, participants will be able to:

  1. Define the term “arson” and list five (5) motives frequently associated with the crime of arson.
  2. Become familiar with origin of the fire and identify eight (8) typical types of evidence found at the scene of arson.
  3. Define the term “ explosives”. Cite the two (2) groups of explosives and identify the two (2) ways that blasting caps are ignited.
  4. List seven (7) methods available to detonate a homemade explosive device.
  5. Become familiar with conducting a bombing crime scene search and list nine (9) pieces of equipment that may be required when searching a bombing crime scene.
  6. Differentiate between the obvious and other valuable evidence at a bombing crime scene.
  7. Identify four (4) things that may be determined by a laboratory examiner when analysing evidence obtained from the crime scene
