The Crime Scene And Crime Scene Investigation:
Questions With Thorough Solutions
Crime scene investigation is the____ point for the successful use of physical
evidence by the forensic laboratory Right Ans - starting
Seasoned crime scene investigators report Right Ans - that everything is
evidence until shown otherwise
methodical process following a set of guidelines, principles, and procedures to
ensure that all of the physical evidence is discovered and investigated
Right Ans - 1. physical evidence recognition
2. documentation
3. proper evidence collection
4. packaging
5. preservation
Once a crime scene is created Right Ans - it immediately begins to change
and decay.
location Right Ans - Crime scenes can be classified according to the location
of the original criminal activity: This classification of the crime scene labels
the site of the original or first criminal activity as the primary crime scene and
any subsequent crime scenes as secondary crime scenes
size of crime scene classificaiton Right Ans - a single macroscopic crime
scene such as a house may actually be composed of many smaller or
microscopic crime scenes, For example, a gunshot victim's body dumped in a
field represents the following crime scenes within the overall crime scene of
the field: the body, the body's wounds, and the ground around the body. The
microscopic classification of the scene is more focused on the specific types of
physical evidence found in the macroscopic crime scenes. Using the previous
example, the microscopic crime scenes are the trace evidence on the body, the
, gunshot residue around the wound, and the tire tread marks in the ground
next to the body
Crime scenes ___ static Right Ans - are not, investigators may need to
update their assessments as their work progresses. Spatial boundaries of
scenes may change as the processing continues and the crime scene can be
expected to expand and change as the evidence dictates.
objectives of any crime scene investigation are to Right Ans - recognize,
preserve, collect, and interpret all of the relevant physical evidence at a crime
scene with the goal of reconstructing the events that generated this evidence
basis of scientific crime scene investigation Right Ans - The integration of
the crime scene investigation with forensic testing of the physical evidence
following types of information that may gleaned from a crime scene Right
Ans - 1. Linkage of persons, scenes, or objects, 2. investigative leads, 3.
Information on the corpus delicti, 4. Information on the modus operandi, 5.
Proving or disproving witness statements, 6. Identification of the suspect(s),
7. Identification of unknown substances, 8. Reconstruction of a crime
Linkage of persons, scenes, or objects Right Ans - this is the principle
behind all crime scene investigations; Locard's exchange principle. Linking
suspects to victims is the most important and common type of linkage made
by physical evidence in criminal investigations
Investigative leads Right Ans - Physical evidence can provide direct
information to an investigator; however, not all physical evidence at the crime
scene will be directly linked to a suspect. Frequently, the physical evidence
will provide indirect information or investigative leads to the investigator. Not
every crime scene has individualizing physical evidence, such as fingerprints,
but every crime scene will have physical evidence that assists the investigator
with information, such as a footwear impression's manufacturer or the size
and type of shoe worn by the suspect.
Information on the corpus delicti Right Ans - Determination of the essential
facts of an investigation involves the physical evidence itself, patterns of the
evidence, and laboratory examinations of the evidence. The red-brown stains
