The proper way to record these later recollections of fact is to immediately start a new note page, using the current time and date, make a reference to the previous case-notes, previous time, date, and page number, and record the newly recalled fact or facts.
These processes present several challenges: Physical evidence can be transient or time sensitive. Identifying the vehicles parked in proximity to the crimes scene or returning to the crime scene on subsequent days around the time of the crime can assist in identifying a witness whose normal course of activities may have previously put them in the area at the time of the crime.
How to process a crime scene step by step
The Pre-Crime Stage occurs when evidence of preparation or planning can be found during the investigation. Loss of Continuity Like controlling contamination, establishing and maintaining continuity of evidence are protocols that protect the integrity of that evidence. This is not to say that investigators attending in tactical investigative response mode should totally ignore evidence, or should be careless with evidence if they can protect it; however, if evidence cannot be protected during the tactical investigative response mode, the court will accept this as a reality.

If a person is a suspect or is a person who may become a suspect, make every effort to record any statements made by that person verbatim. Recording the critical details being conveyed will provide a written record of the facts considered to form reasonable grounds for belief. This unwanted alteration of evidence can wipe away original evidence transfer, dilute a sample, or deposit misleading new materials onto an exhibit. Canvassing can also take the form of structured media releases to request persons with knowledge of the criminal event to come forward.
