Section 2.3: Crime Scene Note Taking

Accurate and comprehensive note-taking stands as a cornerstone of meticulous crime scene documentation. From the moment a call reaches dispatch, the intricate process of documenting every detail begins. Capturing the time of the call, the identity of the caller, and all pertinent details forms the foundation of a reliable investigative record.

The Importance of Detailed Notes

These notes serve as an enduring record of the case’s facts, instrumental in the ongoing investigation, report writing, and eventual prosecution. The depth and accuracy of these notes can significantly impact the outcome of a case. Initial impressions of the scene are crucial. Investigators are trained to utilize all their senses, not just sight. The smell of smoke or the faint sound of a ticking clock might provide critical clues. Attention to transient evidence—elements that could move, alter, or vanish—is paramount at this early stage. Moreover, any deviations from standard procedure must be meticulously recorded.

Continuous Documentation

The task of note-taking begins with the initial call and extends throughout the investigation. This continuous record includes witness statements, which are vital. Effective interviewing skills are essential, and whenever possible, having witnesses write down their accounts is beneficial.

Document everything related to the investigation, from actions taken to information gathered. It’s crucial to record all facts objectively, as establishing a suspect’s innocence is equally as important as proving guilt. Misdirected efforts not only waste valuable time but can also divert resources from uncovering the truth.

Ensure that each note includes the call’s time and date, the location from where the call was made, the assigned officer, and the arrival time at the scene. This practice is essential, even if dispatch logs these details, to ensure nothing is overlooked.

Key Questions for Every Scene

Certain questions are universally relevant across all crime scenes: Who? What? When? Where? Why? How? Recording information that addresses these inquiries is vital. While some questions are general and apply broadly, others will be specific to the case at hand.

By adhering to these practices, investigators ensure they collect a thorough and accurate account of the crime scene. This diligence in note-taking not only aids in the immediate investigation but also contributes to a well-founded case that stands up to scrutiny during prosecution.
