What is crime scene alteration?

Crime scene alteration refers to the act of changing or modifying a crime scene, which can occur for various reasons, often in the context of rendering aid to victims or securing the area. This alteration is sometimes unavoidable as first responders may need to provide medical assistance or evacuate individuals, which can inadvertently disrupt the integrity of the scene.

Understanding crime scene alteration is crucial for investigators, as they must account for any changes that may have occurred before they arrive. Such acknowledgment helps in preserving the initial conditions of the scene and gathering accurate evidence. Recognizing that alterations can impact the investigation underlines the importance of proper procedures and protocols to minimize such changes, if possible, while still ensuring the safety of victims and onlookers.
