Which factor is NOT typically influenced by environmental conditions at a crime scene?

The factor that is not typically influenced by environmental conditions at a crime scene is suspect behavior. While environmental factors such as temperature, humidity, or exposure to elements can significantly affect the integrity of physical evidence and its reliability, suspect behavior is more influenced by psychological, social, and situational factors rather than strictly environmental conditions.

For example, the choice of a suspect to flee or cooperate during a crime scene investigation relates more to their mental state and decision-making processes than to external environmental influences. In contrast, evidence degradation is directly impacted by conditions such as moisture and temperature, which can compromise the quality of physical evidence. Similarly, analysis processes may be tailored based on how environmental factors affect the evidence collected. Thus, suspect behavior stands apart from the direct influence of environmental conditions at a crime scene.
