Section 1: Investigative Process and Preliminary Investigation (Questions 1-20)
Q1: The first responding officer to a crime scene has which of the following priorities? (Select all
that apply)
A. Secure the scene and establish perimeters
B. Provide medical assistance to injured persons
C. Apprehend any suspects still on scene
D. Conduct a detailed interview of all witnesses
[CORRECT] A, B, C
Rationale:
The initial responding officer's priorities (in order) are: officer safety, medical assistance, suspect
apprehension, scene security (establish inner and outer perimeters). Detailed witness
interviews occur during the preliminary investigation after the scene is secured. This follows
MPTC curriculum on preliminary investigation procedures.
Q2: The principle that states "every contact leaves a trace" is known as:
A. Chain of custody
B. Locard's Exchange Principle
C. Modus operandi
D. Corpus delicti
[CORRECT] B. Locard's Exchange Principle
Rationale:
,Locard's Exchange Principle, formulated by Dr. Edmond Locard, states that whenever two
objects come into contact, there is an exchange of materials (hair, fibers, soil, fingerprints, DNA,
etc.). This is the foundation of forensic science and trace evidence collection. The principle is
fundamental to MPTC crime scene management training.
Q3: Solvability factors used to determine whether a case should be assigned for follow-up
investigation include: (Select all that apply)
A. Witnesses who can identify the suspect
B. Physical evidence that can be processed
C. Suspect identity known
D. Modus operandi that matches other cases
[CORRECT] A, B, C, D
Rationale:
Solvability factors include: witnesses who can identify the suspect, physical evidence that can be
processed, suspect identity known, modus operandi (MO) that matches other cases, suspect
vehicle, suspect address, and any other information that could lead to arrest. These factors help
supervisors determine which cases have the highest probability of clearance and should receive
follow-up investigation resources.
Q4: The term "corpus delicti" refers to:
A. The suspect's confession
B. The body of the victim in a homicide case
C. The proof that a crime has been committed (the body of the crime)
D. The physical evidence collected at the scene
[CORRECT] C. The proof that a crime has been committed (the body of the crime)
Rationale:
Corpus delicti (Latin for "body of the crime") means the proof that a crime has been committed.
For a homicide, it requires proof that a person is dead and that the death was caused by
criminal means (not just a body). A confession alone is insufficient for conviction; independent
evidence of corpus delicti is required under Massachusetts law.
Q5: In criminal investigation, "victimology" refers to:
, A. The study of the victim's criminal history
B. The comprehensive study of the victim to identify risk factors and potential suspects
C. The classification of victims by age and gender only
D. The psychological profile of the offender
[CORRECT] B. The comprehensive study of the victim to identify risk factors and potential
suspects
Rationale:
Victimology is the comprehensive study of the victim including their lifestyle, relationships,
occupation, habits, routines, and risk factors. This analysis helps investigators identify potential
suspects (those with access), understand the motive, and determine if the victim was targeted
randomly or specifically. It is a critical component of the investigative process per MPTC
standards.
Q6: Which of the following is NOT a classification of motive in criminal investigations?
A. Financial gain
B. Power/control
C. Accidental opportunity
D. Ideological
[CORRECT] C. Accidental opportunity
Rationale:
Motive classifications include: power/control, revenge, jealousy, financial gain, ideological,
sexual, and gang-related. "Accidental opportunity" describes a situational factor, not a motive
classification. While opportunity is a component of crime (means, motive, opportunity), it is not
classified as a type of motive in investigative analysis.
Q7: A "signature" in criminal investigation refers to:
A. The suspect's written name at the scene
B. A unique behavioral aspect that is not necessary for the completion of the crime
C. The method of operation used to commit the crime
D. The legal document authorizing the investigation
