Arson Investigations


An Overview of Arson Investigation

Arson Investigations involve the study of fire-damaged physical evidence and crime scenes to detect arson, which is the crime of setting a fire for an unlawful or improper purpose. The techniques involved in arson investigations require a basic understanding of the chemistry of explosives. In addition, an investigator must understand the materials used in the formation of explosives. Also, they need to understand the various ways in which explosives are interrelated and initiated.

Arson investigations, also known as fire investigations, are the investigation and analysis of fire-related incidents. Detectives use a variety of forensic analysis methods, crime scene investigation techniques, and chemical analysis to evaluate a fire scene.

After firefighters or firemen extinguish a fire, a fire investigation seeks to determine the cause of the fire or explosion. This type of crime is one of the most common and most expensive crimes committed.  Private investigators with experience as a fireman or fire marshals may specialize in conducting this type of investigation.

Private investigators may engage in conducting actual fire investigations, insurance fraud investigations, or forensic investigations.
