What are the three primary types of sketches used in crime scene investigations?

In crime scene investigations, sketches play a crucial role in documenting and visualizing the scene. The three primary types of sketches used are Bird's Eye View, Elevation, and Exploded sketches.

A Bird's Eye View sketch provides a top-down perspective of the crime scene, allowing investigators to see the layout and spatial relationships between evidence and other items of interest. This type of sketch is essential for understanding how different elements in the scene are positioned relative to one another.

Elevation sketches are used to depict vertical aspects of the scene. They show the height of objects, such as wounds on a wall or the heights of furniture, helping to convey more detailed spatial information that a two-dimensional layout might miss.

Exploded sketches combine elements of both overhead and elevation perspectives to showcase the relationships of objects in three dimensions. This can be particularly helpful for complex crime scenes or when depicting items that are stacked, layered, or positioned in a way that would be difficult to convey in a flat illustration.

These three types of sketches are fundamental for documenting the crime scene accurately, ensuring that all important details can be communicated effectively to investigators, forensic teams, and the courts. Each type serves a specific purpose, contributing to the overall understanding and analysis of the crime scene.
