Who is NOT typically considered a key witness at a fire scene?

In a fire investigation, key witnesses are typically individuals who have direct knowledge or involvement with the circumstances leading to the fire or related to any injuries or fatalities. The firefighting team leader, while crucial in coordinating response efforts and ensuring the safe management of the scene, does not usually possess firsthand knowledge about the events leading to the fire. This role is more focused on tactical operations and the management of resources rather than the specifics of the victim’s last moments or the discovery of the fire.

Conversely, the other individuals mentioned—such as the person discovering the victim, the last person to see the victim alive, and the person discovering the fire—have vital information that can provide insights into the timeline of events, the state of the victim, and critical details regarding the fire's origins. These elements are essential in establishing causes and circumstances surrounding the incident. Hence, the reason the firefighting team leader is not classified as a key witness revolves around their lack of direct, relevant experience of the events leading up to or surrounding the fire incident in question.
