Elements of Investigation0

  • 5

  • 7

    Review the legal and acceptable methods for collecting, packaging, and preserving physical evidence and the initiation and maintenance of the chain of custody. Using a mock crime scene:7

    1. A

      Document the crime scene using the steps identified in standard 107A

    2. B

      Demonstrate proper methods of evidence collection and packaging7B

    3. C

      Initiate the chain of custody for each piece of evidence collected7C

  • 8

    Identify emerging technologies and techniques being utilized by law enforcement while gathering and processing evidence at a crime scene and in the laboratory. Review a current or recent court case that utilized one of these technologies or techniques, and decide if the use of the technology/technique infringed on the defendant’s rights.8

Physical Evidence Analysis0

  • 9

    Investigate the science surrounding the physical properties of matter, and explain how they are related to the role of the law enforcement officer when collecting evidence. Apply the principles of temperature, weight and mass, density, and refractive index in the context of forensic science.9

  • 10

    Explain the physical composition of glass and relate the characteristics of various types such as tempered and laminated. Demonstrate the skill of identifying the classifications of glass fragments, and calculate the projectile path by examining glass fractures at a simulated scene.10

  • 11

    Examine the forensic tools used in a field sobriety test and a blood alcohol test, and describe legal guidelines that must be followed when performing each of these tests as they relate to the constitutional rights of suspects. Evaluate concepts of toxicology and metabolism of alcohol, and determine the effects of alcohol on persons of different weights, ages, and genders.11

  • 12

    Evaluate a death related to chemicals that can be harmful or poisonous to the human body, such as drugs or carbon monoxide. Describe the process for collecting and preserving toxicology evidence and the techniques used for detecting the type of substance.12

  • 13

    Analyze the scientific basis of tests performed on various body fluids and/or stains at a crime scene to determine their origins. Demonstrate collection of simulated body fluids from a staged crime scene to preserve and prevent contamination of the sample. Include in the demonstration compliance with OSHA standards of practice when dealing with blood and body fluids.13

  • 14

    Describe the techniques used to excavate bones from a crime scene and the methods for distinguishing human bones from animal bones. Identify the parameters for determining the age, sex, and possible ethnicity of a human skull.14

  • 15

    Review an autopsy report to determine the time and cause of death through evaluation of body temperature, rigor mortis, post mortem lividity, appearance of eyes, skin color, and presence of arthropods. Document findings in an appropriate format.15

  • 16

    Link the development of DNA testing and the Combined DNA Index System (CODIS) with changes in the criminal justice system, using professional journals, case studies, court cases, or interviews with law enforcement or forensic scientists.16

  • 17

    Document the interpretation of a simulated bloodstain pattern, including the following information:17

    1. A

      Data gathered from pattern analysis concerning the violent event17A

    2. B

      Impact of surface texture, directionality, and angle on pattern17B

    3. C

      Calculation of angle of impact17C

    4. D

  • 20

    Identify the recognizable characteristics, from bullets and cartridge casings, at a staged crime scene or from a case study. Explain, using a visual, how these characteristics are placed in the National Integrated Ballistics Information Network and the uses of the network by local, state, and federal law enforcement.20

  • 21

    Research the concepts surrounding bullet trajectory and its uses in criminal investigations for determining victim and suspect locations and movements at a crime scene. Prepare a professional written report summarizing this information. 21
