Answer:
In the case of arson, investigators must look for the most intensely burned debris to find the origin of the fire. In the case of an explosion, there will also be a crater at the site of the blast. With either type of event, chemical residues can tell how the event happened.
The arson and explosion investigator must take detailed notes during every step of the process. These notes are used to write a full report about the analysis and its conclusions. If the evidence from the analysis is used in a case that goes to trial, the arson and explosion investigator may be required to testify in court about the work.
Arson and explosion investigation is an inspiring field of forensic science that will continue to provide exciting career opportunities well into the future.
