“Crime scene management, and evidence management as a critical part of that, must be learned and incorporated into the investigator’s toolkit.” Show
Crime scene management skills are an extremely significant task component of investigation because evidence that originates at the crime scene will provide a picture of events for the court to consider in its deliberations. That picture will be composed of witness testimony, crime scene photographs, physical exhibits, and the analysis of those exhibits, along with the analysis of the crime scene itself. From this chapter, you will learn the task processes and protocols for several important issues in crime scene management. These include:
Topic 1: Note TakingAlthough other documents will be created by the investigator to manage the crime scene, no other document will be as important to the investigator as the notebook. The notebook is the investigator’s personal reference for recording the investigation. Many variations of police notebooks have emerged over the years. The court will sometimes even accept police notes that have been made on a scrap of paper if that was the only paper available at the time. However, beyond extreme circumstances, in operational investigations, the accepted parameters of a police notes and notebooks are:
In court, the investigator’s notebook is their best reference document. When testifying, the court will allow an investigator to refer to notes made at the time to refresh their memory of events and actions taken. When an investigator’s notebook is examined by the court, notes consistent with the investigator’s testimony provide the court with a circumstantial assurance or truthfulness that the evidence is accurate and truthful (McRory, 2014). Alternately, if critical portions of the investigation are not properly recorded or are missing from the notebook, those portions of the evidence will be more closely scrutinized by the defence. The court may give those unrecorded facts less weight in its final deliberations to decide proof beyond a reasonable doubt. For an investigator, good notes are an overview of the things seen/heard and the actions taken. A chronology of notes demonstrates the investigator’s mental map of the facts that led to forming reasonable grounds for an arrest and charges. Court cases are often extended by adjournments, appeals, or suspects evading immediate capture. This can extend the time between the investigation and the trial by several years. In these protracted cases, it becomes critical for the investigator to have detailed notes that accurately reflect their investigation to trigger their memory of the facts. As important as the notebook is, note taking skills are often an underemphasized aspect of police training. Most police investigators develop their personal skills and note taking strategies through on the job experience and in the “trial by fire” of cross examination in court. This void in the training of note taking skills is likely due to the broad range of circumstances under which note taking needs to take place and because it is impossible to anticipate what facts will become important in every possible variation of circumstances. Thus, some combination of training, common sense, and experience will come into play for investigators to become proficient in recognizing what to record in their notebook. The concept of “notes made at the time of an event is a rather misleading definition and requires some explanation. In an ideal world, an investigator would be able to proceed through an investigation with an open notebook and record each fact and each observation of events as they transpire. Of course, the way events unfold is dynamic and unpredictable. Circumstances often require an investigator to be fully engaged in efforts to bring a situation under control, while protecting the life and safety of persons. There is no place for an open notebook in such cases and the investigator is clearly not taking any notes at that time, but will do so after the event is under control, and as soon as it is practical to do so. Although the typical reference in court is to notes made at the time, in actuality, they are notes made as soon as practical under the unique circumstances of the event. The courts do accept the operational dynamics that exists for investigators, and it sometimes becomes a question at trial to know when the notes were actually composed. As such, an investigator should always be prepared to answer this question. Having a note in the notebook regarding the time when the writing of notes was and finished acts as a reference to demonstrate awareness and attention to this issue. Another issue related to notes made at the time is the dilemma of facts that were overlooked and then recalled after the initial notes have been completed. The human memory does have its limitations and flaws. On occasion, an investigator will complete the initial draft of their notes, and, at some later time may suddenly recall a point that was missed. On such occasions, returning to the pages of notes made at the time and attempting to insert the recalled facts is not an acceptable practice. 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 kinds of recalled facts and late entries will be closely examined by defence counsel, and it can sometimes be helpful if the investigator can also make note of the fact or circumstances that led to the recollection of the additional information. Anyone who has ever participated in a critical incident, where life and safety have taken priority, can tell you that once the event is under control, investigators can be seen writing intently to document their recollection of the events. The following strategies are recommended as a general guide to note taking:
It is the personal responsibility of each investigator to document their personal perception and recollection of the event they are witnessing, as it unfolds. In cases where investigators have collaborated on an agreed version of events and authored their notes to reflect those agreed upon facts, the notes are no longer the personal recollection of that investigator and, as such, may be scrutinized as being a collective version of events aimed at producing evidence that does not reflect a true account of the facts as they were witnessed by each individual investigator. The practice of collaborating and making collective notes is sometimes called “boxing of notes” — this practice can be discovered by defence when the individual notebooks of investigators are identical or close to identical in format and content. The practice of boxing of notes has been identified as one of the flaws in investigative practice that can lead to miscarriages of justice (Salhany, 2008). As such, collaboration between investigators when making notes should be avoided. If, at any point, there is a collaboration to return to an issue together and re-examine physical evidence to clarify the point for each investigator, that collaborative effort should be noted as part of the note making of each investigator. Despite this caution regarding the collective production of notes, there are occasions where a collective note making process is used and is accepted as reasonable. This occurs during large scale operations involving many participants, sometimes coordinated by an Emergency Operations Command Center. In these cases, there is a need for the command centre participants to be completely engaged in handling the event, which may extend over periods of hours or days. The practice of each participant waiting until the protracted event has been concluded to make their individual notes would be impractical and potentially inaccurate. In these cases, it is now accepted operational practice to assign one person in the command centre to act as the collective maker-of-notes to substitute for individual note-taking. The note maker in these situations is known as “The Scribe.” For the persons in the command centre to be aware of the notes being made, the Scribe does not make notes into a typical notebook. In such cases, the notes are made onto large pieces of flipchart paper and, as each sheet of notes is completed, it is posted onto the wall of the command centre where each participant can reference the content of the notes and verify the accuracy of the notes. At the end of the operation, the collective pages of notes are photographed and the note pages are saved by the scribe as an exhibit. Each page is often initialled by the participants. Under this process, each participant in the command centre may adopt these notes as a reference document for court purposes. Topic 2: Integrity of the Crime SceneAs part of crime scene management, protecting the integrity of the crime scene involves several specific processes that fall under the Tasks category of the STAIR Tool. These are tasks that must be performed by the investigator to identify, collect, preserve, and protect evidence to ensure that it will be accepted by the court. These tasks include: a) Locking down the crime scene b) Setting up crime scene perimeters c) Establishing a path of contamination d) Establishing crime scene security When an investigator arrives at a crime scene, the need to protect that crime scene becomes a requirement as soon as it has been determined that the criminal event has become an inactive event and the investigator has switched to a strategic investigative response. As you will recall from the Response Transition Matrix, it is sometimes the case that investigators arrive at an active event in tactical investigative response mode. In these cases their first priority is to protect the life and safety of people, the need to protect the crime scene and its related evidence is a secondary concern. 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. As soon as the event transitions to an inactive event with a strategic investigative response, the expectations of the court, regarding the protection of the crime scene and the evidence, will change. This change means that there is an immediate requirement for the investigator to take control of and lock down that crime scene. a) Locking Down the Crime SceneVery often, when the change to strategic investigative response is recognized, first responders and witnesses, victims, or the arrested suspect may still be inside the crime scene at the conclusion of the active event. All these people have been involved in activities at the crime scene up to this point in time, and those activities could have contaminated the crime scene in various ways. Locking down the crime scene means that all ongoing activities inside the crime scene must stop, and everyone must leave the crime scene to a location some distance from the crime scene area. Once everyone has been removed from the crime scene, a physical barrier, usually police tape, is placed around the outside edges of the crime scene. Defining of the edges of the crime scene with tape is known as establishing a crime scene perimeter. This process of isolating the crime scene inside a perimeter is known as locking down the crime scene. b) Crime Scene PerimeterThe crime scene perimeter defines the size of the crime scene, and it is up to the investigator to decide how big the crime scene needs to be. The size of a crime scene is usually defined by the area where the criminal acts have taken place. This includes all areas where the suspect has had any interaction or activity within that scene, including points of entry and points of exit. The perimeter is also defined by areas where the interaction between the suspect and a victim took place. In some cases, where there is extended interaction between a suspect and a victim over time and that activity has happened over a distance or in several areas, the investigator may need to identify one large crime scene, or several smaller crime scene areas to set crime scene perimeters. Considering the three stages of originating evidence, an investigator may find that pre-crime or post-crime activity requires the crime scene perimeter to surround a larger area, or there maybe even be an additional separate crime scene that needs to be considered. For some crime scenes where there are natural barriers, such as buildings with doorways, it is easy to create a crime scene perimeter defining access. This becomes more complicated in outdoor venues or large indoor public venues, where fencing and barricades may be needed along with tape markers to define the perimeters. Once the crime scene perimeter has been established and lock down has taken place, it becomes necessary to ensure that no unauthorized persons cross that perimeter. Typically, and ideally, there will only be one controlled access point to the crime scene, and that point will be at the entry point for the path of contamination. c) Path of ContaminationIt is not possible to eliminate all potential contamination of a crime scene. We can only control and record ongoing contamination with a goal to avoid damaging the forensic integrity of the crime scene and the exhibits. Once a crime scene has been cleared of victims, witnesses, suspects, first responders, and investigators, it is necessary to record, in notes or a statement from each person, what contamination they have caused to the scene. The information being gathered will document what evidence has been moved, what evidence has been handled, and by whom. With this information, the investigator can establish a baseline or status of existing contamination in the crime scene. If something has been moved or handled in a manner that has contaminated that item before the lock down, it may still be possible to get an acceptable analysis of that item if the contamination can be explained and quantified. As an example, sometimes in cases of serious assaults or even murders, paramedics have been present at the scene treating injured persons. When this treatment is happening, non-suspect-related DNA transfer between persons and exhibits can occur. Determining those possibilities is one of the first steps in establishing the level of existing contamination at the time of lock down. With everyone now outside the crime scene and the perimeter locked down, the next step is to establish a designated pathway where authorized personnel can re-enter the crime scene to conduct their investigative duties. This pathway is known as a path of contamination and it is established by the first investigator to re-enter the crime scene after it has been locked down. Prior to re-entering, this first investigator will take a photograph showing the proposed area where the path of contamination will extend, and then, dressed in the sterile crime scene apparel, the investigator will enter and mark the floor with tape to designate the pathway that others must follow. In creating this pathway, the first investigator will avoid placing the pathway in a location where it will interfere with apparently existing evidence and will place it only where it is required to gain a physical view of the entire crime scene. As other investigators and forensic specialists enter the crime scene to perform their duties, they will stay within the path of contamination and, when they leave the path to perform a specific duty of investigation or examination, they will record their departure from the path and will be prepared to demonstrate their departure from the pathway and explain any new contamination caused by them, such as dusting for fingerprints or taking exhibits. d) Crime Scene SecurityAt the same time the crime scene is being defined with perimeter tape, it is also necessary to establish a security system that will ensure that no unauthorized person(s) enters the crime scene and causes contamination. For this purpose, a crime scene security officer is assigned to regulate the coming and going of persons from that crime scene. For the assigned security officer, this becomes a dedicated duty of guarding the crime scene and only allowing access to persons who have authorized investigative duties inside the crime scene. These persons might include:
To maintain a record of everyone coming and going from the crime scene, a document, known as a “Crime Scene Security Log,” is established, and each authorized person is signed in as they enter and signed out as they depart the scene with a short note stating the reason for their entry. Any unauthorized person who enters or attempts to enter a crime scene should be challenged by the crime scene security officer, and, if that person refuses to leave, they can be arrested, removed from the scene, and charged for obstructing a police officer. The assigned security officer is responsible for creating and maintaining the Crime Security Log, which can take various forms. In short term, small scale investigations, it may only require a single page in the security officer’s note book; however, in a large scale, long term investigation, the log could include volumes of pages under the care of several assigned security officers working in shifts. Whatever the scale or format, the security log records who attended the scene, when they attended, why they were there, and when they left the scene. An example of a crime scene security log is shown in the following example. [Long Description]Topic 3: Evidence ManagementAs we have already learned in the STAIR tool, analysis is the process that must occur to establish connections between the victims, witnesses, and suspects in relation to the criminal event. The crime scene is often a nexus of those events and consequently, it requires a systematic approach to ensure that the evidence gathered will be acceptable in court. Exhibits, such as blood, hair, fibre, fingerprints, and other objects requiring forensic analysis, may illustrate spatial relationships through evidence transfers. Other types of physical evidence may establish timelines and circumstantial indications of motive, opportunity, or means. All evidence within the physical environment of the crime scene is critically important to the investigative process. At any crime scene, the two greatest challenges to the physical evidence are contamination and loss of continuity. Contamination of EvidenceContamination is the unwanted alteration of evidence that could affect the integrity of the original exhibit or the crime scene. This unwanted alteration of evidence can wipe away original evidence transfer, dilute a sample, or deposit misleading new materials onto an exhibit. Just as evidence transfer between a suspect and the crime scene or the suspect and the victim can establish a circumstantial connection, contamination can compromise the analysis of the original evidence transfer to the extent that the court may not accept the analysis and the inference that the analysis might otherwise have shown. Contamination can take place in any number of ways including:
Contamination is a fact of life for investigators, and any crime scene will have some level of contamination before the scene becomes an inactive event and the police can lock down the location. While issues of life and safety are at risk, the court will accept that some contamination is outside the control of the investigator. That tolerance for controlling contamination changes significantly once the crime scene is locked down and is under control. Once the scene has been locked down, crime scene management procedures must be put in place. Crime scene contamination presents three challenges for investigators, namely:
In regards to the phrase “control ongoing contamination,” the word “control” is used because investigators cannot eliminate ongoing contamination, they can only seek to control it. This practice of identifying and recording the known contamination is necessary, and even if contamination has taken place, identifying and explaining that contamination may salvage the analysis of exhibits that have been contaminated. During the critical period between the lockdown of the crime scene and obtaining a warrant to search the crime scene, investigators need to consider the possibilities for ongoing contamination. If reasonable grounds exist to believe that evidence of the crime will be damaged or destroyed by some threat of contamination, the investigator has the authority, under exigent circumstances, to re-enter that crime scene without a warrant to take the necessary steps to stop or prevent contamination and protect the evidence. The very act of entering the crime scene to collect evidence, and the process of evidence collection, are forms of contamination. The goal in controlling ongoing contamination is to avoid damaging the forensic integrity of the crime scene and its associated exhibits. It is this goal that makes crime scene management procedures essential to the investigative process. Loss of ContinuityLike controlling contamination, establishing and maintaining continuity of evidence are protocols that protect the integrity of that evidence. For any evidence to be accepted by the court, the judge must be satisfied that the exhibit presented is the same item that was taken from the crime scene. Evidence must be presented to demonstrate “the chain of continuity,” which tracks every exhibit from the crime scene to the courtroom. The evidence to show continuity will come from the investigator testifying that the exhibit being presented is the same exhibit that was seized at the crime scene. This testimony is supported by the investigator showing the court their markings on the exhibit or its container. These markings will include the time, date, and investigator initials, as well as a notebook entry showing the time, date, and place when the item was transported and locked away in the main exhibit holding locker. This evidence is further supported by an Exhibit Log that shows the exhibit as part of the crime scene evidence detailing where at the crime scene it was found, by whom it was found, and the supporting initials of anyone else who handled that exhibit from the crime scene continuously to the main exhibit locker. Any process where that exhibit is removed from the main exhibit locker for examination or analysis must be similarly tracked and documented with the initials, time, and date of any other handlers of the item. Any person who has handled the exhibit must be able to take the stand providing testimony that maintains the chain of continuity of the exhibit. These are simple processes yet critical. If they are not followed rigorously, it can result in the exclusion of exhibits based on lost continuity. Attention to Originating Stages of EvidenceOne of the big dilemmas in crime scene management is determining where the criminal event happened or where the event extended to. Making these determinations provides the investigator with the locations where evidence of the crime may be found. This is often not a simple matter of just attending one location or thinking about the criminal event in just a single timeframe. In the investigative process, there are three possible stages of time where evidence can originate. These are the pre-crime stage, the criminal event stage, and the post-crime stage. These three stages of crime can also mean there could be other locations outside the immediately crime scene area where criminal activities might have also taken place and evidence might be found. The point to remember about the originating stages of evidence is that each of these stages provides possibilities for collecting evidence that could connect the suspect to the crime. When considering theory development or making an investigative plan, each of these stages of the criminal event should be considered.
Evidence does not always appear as a fully formed piece of information that offers an immediate connection or an inference to implicate a suspect. It often comes together as fragments of fact in timelines, spatial relationships, and evidence transfers between the originating stages of evidence constructing circumstantial pictures to demonstrate the suspect’s identity, the fact pattern of the crime, opportunity, means, or motive and intent. Enhancing the Value of Evidence RecoveredPieces of physical evidence often referred to as exhibits, have investigative values at two different levels for investigators. At the first level each physical exhibit has a face value represented by what it is and where it exists within the context of the crime scene. For example a bloody shoeprint found on the floor of a crime scene tells us that someone transferred evidence of blood onto their shoe from a source and walked in a particular direction within the crime scene. These are first level interpretations of evidence that we can reconstruct with our own observations. At the second level this same bloody shoeprint may be subjected to forensic examinations that could provide additional information. For example analysis of the shoeprint pattern, size, and accidental characteristics may allow a positive match to the shoe of a suspect, or the blood may be examined to match the DNA of a victim or other originating source. Both these first level and second level values can greatly assist in creating a reconstruction and interpretation of what happened at the crime scene. Physical exhibits that need to be examined, seized, and documented at any crime scene are a major concern for investigators. As mentioned earlier, one of the big challenges for investigators is to identify and document all of the available evidence and information. This raises the important questions of what will become evidence and what is going to be important? When the suspect and the fact-pattern are not immediately apparent, how does an investigator determine which items within the crime scene need to be considered and taken as possible evidence? There are some general practices that can be followed, but a guiding principle of evidence collection followed by most experienced investigators is to err on the side of caution. More is always better than less. To assist in deciding what could possibly become relevant, investigators need to consider:
Once the crime scene examination has been completed, and the crime scene has been unsecured and abandoned as an open area, returning to collect forgotten evidence is often not possible. It is better to collect everything that could possibly be relevant or could become relevant. In terms of searching for evidence, once the crime scene has been locked down and secured, the crime scene itself needs to be considered as the first big exhibit. As the first big exhibit, it needs to be subjected to documentation using photography, video recording, measurements, and diagrams. Within this first big exhibit, other smaller and possibly-related exhibit may be discovered. What items are found and where may show spatial relationships of interaction demonstrating proof to support a sequence of events. This physical evidence will become the benchmark of known facts that investigators can use to verify the stories of victims and witnesses, or even the alibi of a possible suspect. Physical evidence at both level-one and level-two becomes the known facts upon which theories of events may be developed and tested. Any item could be considered evidence if it demonstrates a spatial relationship relative to the place, the people, or the times, relative to the criminal event. The very first step at this point is securing and documenting the crime scene. It is helpful for investigators to recognize that a crime scene is not just a location where exhibits are found, but the crime scene should be considered as a single big exhibit unto itself. Not only will individual exhibits within the crime scene have value as evidence, the spatial relationships between exhibits in the scene may speak as circumstantial evidence to the overall event. To secure the crime scene as the first big exhibit, investigators will conduct a complete walk-through on the path of contamination completely photographing and videotaping the entire crime scene. This first process is very helpful in demonstrating the exact state of the crime scene prior to things being moved for forensic examination. This should happen immediately after lock down and it will become a snapshot demonstrating the existing spatial relationships at that point in time. Creating a Field Sketch and Crime Scene DiagramThe next step is to document the crime scene as either a field sketch or a crime scene diagram. Either of these can be done to illustrate the physical dimensions and notable characteristics of the crime scene. The difference between the Field Sketch and the Crime Scene Diagram is that the sketch, as implied by the name, is a quick rough depiction of the event. The field sketch, like notes in an investigator’s notebook, serves as a memory aid. The crime scene diagram is a more formal representation of the same information, but is composed to scale using the assistance of the field sketch and measurements. In either of these drawings of the crime scene similar core information will be represented.
The Exhibit LogAs part of the evidence management process, establishing the first link in the chain of continuity occurs when the crime scene is secured and the assigned exhibit custodian records of the exhibits that have been identified at the scene is created. These items are recorded in a document called an “Exhibit Log” or an “Exhibit Ledger.” This Exhibit Log or Ledger shows an assigned number for each exhibit that is identified and seized. It shows where at the scene the exhibit was located, and the number of that exhibit is place in the corresponding location in the crime scene diagram. The Exhibit Log shows who seized the exhibit and when it was turned over to the exhibit custodian. The Exhibit Log also shows a time and date when the exhibit was placed into the main secure exhibit storage locker. When the exhibits are taken to court, the court will only accept the exhibits if the secured chain of continuity can be shown to be guarded and unbroken. If an exhibit custodian were to stop and leave the exhibits unguarded in a vehicle or left the exhibit in the office while attending to another matter – that would break the chain of continuity. The following document is an example of a common Exhibit Log Document. Evidence at a crime scene is generally found in two forms. One is evidence of witnesses who can provide their observations of the criminal event. The other is physical items of evidence that can be examined, analyzed, and interpreted to illustrate facts about the criminal event. Each of these forms of evidence present some similar concerns for investigators, and each requires some specific considerations to best search for, collect, and preserve the information that exists. Searching for Witness EvidenceIdentifying and interviewing the witnesses to a criminal event can be as simple as speaking to persons who have remained at the scene of the crime to give statements. Alternately, it can be as difficult as identifying and tracking down a person who saw something or heard something that was part of the criminal event, but they are not even aware that what they saw or heard was important, or they do wish to cooperate with the police. The process searching for witnesses starts at the crime scene itself. This search will include not only identifying and interviewing the persons who are immediately present, but also determining who else might have been present during the pre-crime and post-crime stages of the event.
In addition to these witness search strategies, another process known as canvassing for witnesses can also be employed. Canvassing is a strategy of conducting door-to-door inquiries in the immediate area of the crime to determine if anything was seen or heard by neighbours. Canvassing can also take the form of structured media releases to request persons with knowledge of the criminal event to come forward. Whatever witness identification strategies are used, time is of the essence. Memories fade and people under normal circumstances only retain day-to-day recollection of unremarkable events for a limited time. Identifying and speaking to the witness, and receiving their best recollection of the events, will be discussed in the chapter on witness management; however, witness evidence can make or break the investigation, and it must be collected quickly, accurately, and effectively. Searching for and Identifying Physical EvidenceEarlier in this book, we described physical evidence as the buried treasure for investigators and critical when it comes to verifying or discounting various versions of an event in court. Physical evidence is something tangible that the court can examine and consider in making connections and determining proof beyond a reasonable doubt. In contrast, witness evidence does not have a physical quality that the court can observe. It requires the court to accept the perception and interpretation of events being provided by a person and, as such, the court cannot evaluate witness evidence with the same confidence of verification that it uses when considering physical evidence. In our sub-section on Originating Stages of Evidence, we looked at the timeframes and alternate crime scene venues where evidence of a crime may be found. Now, we are going to consider the physical evidence that investigators should think about when evaluating what might constitute an item of physical evidence. We will consider how evidence can be searched for, how it should be collected, when it should be collected, and how it should be preserved. These processes present several challenges:
Topic 4: Scaling the Investigation to the EventNot every crime scene is a major event that requires an investigator to call out a team and undertake the crime scene and evidence management processes that have been described in this book. Often, for minor crimes, a single investigator will be alone at the crime scene and will engage in all the roles described, albeit on a far smaller scale. When this process is being undertaken by a single investigator on a smaller scale, the issues of diagram, security log, and exhibit log may be limited to data and illustrations in the notebook of the investigator. It is important to stress that each of the tasks below needs to be considered and addressed for every crime scene investigation, no matter how big or how small. Specifically:
Large scale or small scale, all these issues must be considered, addressed, and recorded to satisfy the court that the crime scene and the evidence were handled correctly. SummaryIn this chapter, we have discussed the critical issues of crime scene management, evidence identification, evidence location, evidence collection, evidence protection, and proper documentation. These are the most important skills that an investigator can learn and incorporate into their investigative toolkit. As much as these tasks may seem simplistic, ritualistic, and mundane, they are the very foundation of a criminal investigation, and without this foundation of proper evidence practices in place, the case will collapse when it comes to court. There is a great opportunity on a day-to-day basis for new investigators to begin practicing the protocols of crime scene management on a smaller scale investigating crimes such as break and entry and lower level assaults. Once these skills of crime scene management and evidence management are learned and incorporated into daily practice, they will become the procedural norm and will form the essential operational habits for proper and professional investigative practice.
