What is one of the primary purposes of crime scene sketches?

One of the primary purposes of crime scene sketches is to provide a basis for court exhibits. A sketch offers a visual representation of the crime scene that can illustrate important details, such as the spatial relationships between various pieces of evidence, the layout of the scene, and the position of the victim or any objects involved. This visual aid can enhance the understanding of the case for jurors, judges, and legal professionals when presented in court.

While photographs are crucial for documenting the scene, they may not capture the full context and dynamic relationships that a sketch can provide. A well-drawn sketch can also supplement narratives and reports by offering specific details that reinforce the written account. Unlike witness statements, which capture personal observations and may lack objectivity or exact measurements, sketches are drawn to scale and include important map-like details that are essential for forensic analysis and courtroom presentations.
