How should a rough sketch be created during an investigation?

Creating a rough sketch at the scene of an investigation is essential for capturing accurate details of the environment and layout as they exist at that moment. This immediate sketch allows investigators to document crucial evidence, the positions of objects, and spatial relationships that may be unique to that particular location and time. By sketching in situ, an investigator can ensure that the information is fresh and accurately reflects the conditions observed, which is vital for later analysis.

Additionally, a rough sketch serves as a preliminary tool that can aid in more formal documentation and reporting. It can later be refined or digitized but maintaining the initial integrity of the information is key to a thorough investigative process. Creating the sketch later, whether at the precinct or in a digital format, risks losing valuable context and details that may not be remembered or accurately captured afterward. Similarly, drafting sketches directly within reports can be limiting and may not provide the same level of detail needed for evidence presentation or courtroom purposes.
