What is an indicator of forcible entry during a fire investigation?

Forcible entry during a fire investigation is often indicated by the presence of discarded containers, as these can suggest that someone gained unauthorized access to a property. These containers may include things like tools or materials that were used in breaking locks or windows, which are often left behind at the scene.

When examining evidence, investigators look for objects that might indicate forced entry, and discarded items can reveal both intent and method. They provide critical insights into how an intruder may have accessed a building, especially if they were involved in criminal activity, like arson.

While burn patterns are vital for understanding fire dynamics and determining the origin of a fire, they do not directly indicate the manner in which entry was gained. Utility service interruptions can suggest tampering or neglect but do not provide clarity on forced entry. Footprints can suggest the presence of individuals on the scene, but they don't specifically indicate forcible entry as clearly as discarded containers can, which directly tie to the tools and methods potentially used in the act.
