Where might traces of flammable fluid be found during an arson investigation?

During an arson investigation, traces of flammable fluid can be found in cans at the fire scene and on various objects. This is because arson often involves the use of accelerants to facilitate the spread of flames. Investigators look for evidence of these accelerants not just in the areas that were burned, but also in containers like cans or bottles that may have been used to store the flammable substances. Additionally, various objects in and around the fire scene may show contamination from such fluids, providing crucial evidence that can help determine the cause of the fire and whether it was set intentionally.

Finding flammable fluids in multiple locations increases the chances of collecting valid evidence that links a suspect to the crime or helps to reconstruct the events leading to the fire. This method of investigation is essential for establishing the presence of an accelerant and understanding the unique characteristics of the fire's behavior, which can further substantiate claims of arson.
