Chapter 2: Crime Scene Investigation and Evidence Collection: A Comprehensive Guide
Introduction:
Stepping into the world of crime scene investigation is like entering a complex puzzle. Every shattered shard of glass, every stray fiber, every minute detail holds a potential piece of the truth. Chapter 2 of any forensic science textbook – or any real-life investigation – hinges on meticulous crime scene investigation and evidence collection. This post will delve deep into this critical stage, providing a detailed look at the processes, techniques, and crucial considerations involved in securing, documenting, and collecting evidence that can lead to justice. We will cover everything from initial scene assessment and securing the perimeter to advanced evidence collection methods and chain of custody procedures, ensuring you gain a complete understanding of this pivotal chapter in the investigative process. Prepare to unlock the secrets hidden within the chaos.
1. Securing the Crime Scene: The Foundation of a Successful Investigation
Before any evidence is touched, the scene must be secured. This involves establishing a perimeter to prevent unauthorized access and contamination. Proper scene security is paramount. This involves:
Establishing a perimeter: This typically involves using police tape, barriers, or personnel to restrict entry to authorized individuals only. The size of the perimeter depends on the nature of the crime and the potential distribution of evidence.
Controlling access: A logbook should be maintained to record the entry and exit of all personnel, including their names, affiliations, and time stamps. This creates a documented chain of custody from the very beginning.
Protecting the scene from the elements: Depending on the weather conditions, steps must be taken to protect the scene from rain, sun, or wind. This might involve using tarps, umbrellas, or other protective measures to prevent evidence degradation.
Preventing contamination: Investigators should wear appropriate personal protective equipment (PPE), such as gloves, masks, shoe covers, and coveralls, to prevent contamination of the scene and the transfer of evidence. This is a critical step in maintaining the integrity of the investigation.
2. Documenting the Crime Scene: A Visual Record of Reality
Comprehensive documentation is crucial. This provides a detailed record of the scene's condition before any evidence is disturbed. This includes:
Photography: Detailed photographs are essential. Wide-angle shots establishing the overall scene, mid-range shots showing specific areas of interest, and close-up shots focusing on individual pieces of evidence are all crucial. Photography should be systematic and thorough.
Videography: Video recording provides a dynamic record of the scene, allowing for a more comprehensive review later on. Video can capture details that might be missed in photographs, including the spatial relationships between objects.
Sketching: Detailed sketches of the scene, including measurements and the location of evidence, provide a permanent record that complements photographs and video. These should include a scale and compass direction.
Notes: Thorough notes documenting every aspect of the scene, including the time of arrival, weather conditions, and the actions taken, are essential. This includes details about the location and condition of all evidence found.
3. Searching for and Collecting Evidence: Precision and Methodology
The search for evidence must be methodical and systematic. Different search patterns (grid, spiral, linear, zone) may be employed depending on the size and nature of the scene. Evidence collection requires:
Identifying and classifying evidence: Recognizing different types of evidence (biological, trace, digital, etc.) is crucial for proper collection and analysis. Each type of evidence requires specific handling procedures.
Proper packaging and labeling: Each piece of evidence must be packaged individually to prevent cross-contamination. Labels should include case number, item number, date, time, location, and collector's initials.
Maintaining the chain of custody: A detailed record of who handled the evidence, when, and where must be maintained to ensure its admissibility in court. Any breaks in the chain of custody can severely compromise the integrity of the evidence.
Specialized evidence collection techniques: Different evidence requires different techniques. Collecting fingerprints, DNA samples, trace evidence (hairs, fibers), digital evidence, and firearms all have specific protocols.
4. Chain of Custody: Ensuring Evidence Integrity
The chain of custody documents the movement of evidence from the crime scene to the laboratory and ultimately to the courtroom. Breaks in the chain of custody can render evidence inadmissible in court. Therefore, meticulous record-keeping is essential. This involves:
Detailed logging: Every transfer of evidence must be meticulously documented, including the date, time, location, and individuals involved.
Secure storage: Evidence must be stored in secure locations to prevent tampering or loss. This might involve evidence lockers, secure rooms, or specialized facilities.
Controlled access: Access to evidence should be restricted to authorized personnel only.
Verification: The chain of custody should be verified at each stage of the process to ensure its integrity.
5. Crime Scene Reconstruction: Putting the Pieces Together
Crime scene reconstruction uses the collected evidence to recreate the sequence of events that led to the crime. This involves:
Analyzing evidence: Analyzing the evidence collected at the scene helps establish timelines, movements of individuals, and potential interactions between objects.
Creating timelines: Using evidence like timestamps, witness statements, and physical evidence, investigators can attempt to create a timeline of events.
Developing hypotheses: Based on the evidence and analysis, investigators form hypotheses about what occurred at the scene.
Testing hypotheses: These hypotheses are then tested through further investigation, analysis, and experimentation.

| chapter 2 crime scene investigation and evidence collection: Forensic Analysis National Research Council, Division on Earth and Life Studies, Board on Chemical Sciences and Technology, Committee on Scientific Assessment of Bullet Lead Elemental Composition Comparison, 2004-04-26 Since the 1960s, testimony by representatives of the Federal Bureau of Investigation in thousands of criminal cases has relied on evidence from Compositional Analysis of Bullet Lead (CABL), a forensic technique that compares the elemental composition of bullets found at a crime scene to the elemental composition of bullets found in a suspect's possession. Different from ballistics techniques that compare striations on the barrel of a gun to those on a recovered bullet, CABL is used when no gun is recovered or when bullets are too small or mangled to observe striations. Forensic Analysis: Weighing Bullet Lead Evidence assesses the scientific validity of CABL, finding that the FBI should use a different statistical analysis for the technique and that, given variations in bullet manufacturing processes, expert witnesses should make clear the very limited conclusions that CABL results can support. The report also recommends that the FBI take additional measures to ensure the validity of CABL results, which include improving documentation, publishing details, and improving on training and oversight. |

| chapter 2 crime scene investigation and evidence collection: Forensic Investigations Brent E. Turvey, Stan Crowder, 2017-01-05 The terms forensic investigator and forensic investigation are part of our cultural identity. They can be found in the news, on television, and in film. They are invoked, generally, to imply that highly trained personnel will be collecting some form of physical evidence with eventual scientific results that cannot be questioned or bargained with. In other words, they are invoked to imply the reliability, certainty, and authority of a scientific inquiry. Using cases from the authors' extensive files, Forensic Investigations: An Introduction provides an overview of major subjects related to forensic inquiry and evidence examination. It will prepare Criminal Justice and Criminology students in forensic programs for more specialized courses and provide a valuable resource to newly employed forensic practitioners. Written by practicing and testifying forensic professionals from law enforcement, academia, mental health and the forensic sciences, this work offers a balanced scientific approach, based on the established literature, for broad appeal. The purpose of this book is to help students and professionals rid themselves of the myths and misconceptions they have accumulated regarding forensic investigators and the subsequent forensic investigations they help to conduct. It will help the reader understand the role of the forensic investigator; the nature and variety of forensic investigations that take place in the justice system; and the mechanisms by which such investigations become worthy as evidence in court. Its goals are no loftier than that. However, they could not be more necessary to our understanding of what justice is, how it is most reliably achieved, and how it can be corrupted by those who are burdened with apathy and alternative motives. - A primary text for instructors teaching forensic courses related to criminal and forensic investigation - Written by forensic professionals, currently in practice and testifying in court - Offers applied protocols for a broad range of forensic investigations - Augments theoretical constructs with recent, and relevant case studies and forensic reports - Based on the most recent scientific research, practice, and protocols related to forensic inquiry |

| chapter 2 crime scene investigation and evidence collection: The Social Life of Forensic Evidence Corinna Kruse, 2015-12-29 In The Social Life of Forensic Evidence, Corinna Kruse provides a major contribution to understanding forensic evidence and its role in the criminal justice system. Arguing that forensic evidence can be understood as a form of knowledge, she reveals that each piece of evidence has a social life and biography. Kruse shows how the crime scene examination is as crucial to the creation of forensic evidence as laboratory analyses, the plaintiff, witness, and suspect statements elicited by police investigators, and the interpretations that prosecutors and defense lawyers bring to the evidence. Drawing on ethnographic data from Sweden and on theory from both anthropology and science and technology studies, she examines how forensic evidence is produced and how it creates social relationships as cases move from crime scene to courtroom. She demonstrates that forensic evidence is neither a fixed entity nor solely material, but is inseparably part of and made through particular legal, social, and technological practices. |

| chapter 2 crime scene investigation and evidence collection: Digital Forensics and Investigations Jason Sachowski, 2018-05-16 Digital forensics has been a discipline of Information Security for decades now. Its principles, methodologies, and techniques have remained consistent despite the evolution of technology, and, ultimately, it and can be applied to any form of digital data. However, within a corporate environment, digital forensic professionals are particularly challenged. They must maintain the legal admissibility and forensic viability of digital evidence in support of a broad range of different business functions that include incident response, electronic discovery (ediscovery), and ensuring the controls and accountability of such information across networks. Digital Forensics and Investigations: People, Process, and Technologies to Defend the Enterprise provides the methodologies and strategies necessary for these key business functions to seamlessly integrate digital forensic capabilities to guarantee the admissibility and integrity of digital evidence. In many books, the focus on digital evidence is primarily in the technical, software, and investigative elements, of which there are numerous publications. What tends to get overlooked are the people and process elements within the organization. Taking a step back, the book outlines the importance of integrating and accounting for the people, process, and technology components of digital forensics. In essence, to establish a holistic paradigm—and best-practice procedure and policy approach—to defending the enterprise. This book serves as a roadmap for professionals to successfully integrate an organization’s people, process, and technology with other key business functions in an enterprise’s digital forensic capabilities. |
