1. Trained inveѕtіgаtors know to сollесt evіdenсе bаѕed on its pоtеntіаl imрortanсе.
a. True
b. False
ANSWER: False
RATIONALE: The trained investigator collects all available evidence, without making judgments about its
potential importance. That comes later. Knowing which evidence is significant requires the ability
to recreate the series of events preceding the crime. The first step is careful and accurate
observation.

a. True
b. False
ANSWER: True
RATIONALE: Scientists have established a rigorous study procedure known as the scientific method. After stating
the problem or question, the scientist proposes a hypothesis based on prior knowledge or
observation. A hypothesis is a possible explanation of a question or problem based on prior
knowledge or observation. It is not a guess.

a. True
b. False
ANSWER: False
RATIONALE: An observation is what a person perceives using their senses. Every single moment, we are
gathering information about what is around us, through our senses—sight, taste, hearing, smell, and
touch. The sensory information that we observe is delivered to our brain. Perception is our brain’s
interpretation of our sensory observations after our brains have filtered and processed the
information.

a. True
b. False
ANSWER: False
RATIONALE: Information is processed in the brain in the following order: information enters the brain through
sensory inputs; we pay attention to only some of the information; this information is then processed
through our perception. Of the perceived information, only a portion passes on to short-term
memory, and even less of that information then becomes long-term memory.

a. True
b. False
ANSWER: False
RATIONALE: An eyewitness is a person who has seen someone or something related to a crime and can
communicate their observations. Memory fades with time, and our brains tend to fill in details that
we feel are appropriate but may not be accurate. The use of “six packs” of photos (six-person photo
collection) by law enforcement agencies is under review. Some experts feel their use prejudices
witnesses who want to be helpful and feel the suspect must be in the photo array.

Сhaрter 01 Forenѕiс Ѕсіеnсe ‌аnd Obѕervation

ANSWER: True
RATIONALE: When evaluating eyewitness testimony, the investigator must discriminate between fact, a statement
or information that can be verified, and opinion, a personal belief founded on judgment rather than
on direct experience or knowledge. Often what we think we saw and what really happened differ.
Someone fleeing the site of a shooting might look like a suspect but could merely be an innocent
bystander running away in fear of being shot.

a. True
b. False
ANSWER: True
RATIONALE: We know that we are not naturally inclined to pay attention to all of the details of our surroundings.
To be a good observer, we must make a conscious effort to examine our environment
systematically.

a. True
b. False
ANSWER: False
RATIONALE: A good interviewer uses other techniques to determine if an eyewitness is telling the truth or if they
are lying. If a witness is telling the truth, the account of what happened is consistent each time they
tell the story. If the witness is lying, it is more difficult to repeat the events exactly the same.

9.‍Effective intеrvіewerѕ рrovidе ‌conѕiderablе guіdanсе tо gеt the most informatіоn posѕіblе from аn eyewіtnеѕѕ.
a. True
b. False
ANSWER: False
RATIONALE: The most effective interviewers provide minimal guidance but instead ask questions that may help
the person reconstruct what occurred. It is important for the interviewer to conduct the interview
without interjecting any biases. By avoiding gender-specific terms such as he or she, the interviewer
does not provide any information that may influence the eyewitness’s perception of what or who
they saw. The goal is to play back the witness’s memory, not reconstruct it for them.

a. True
b. False
ANSWER: False
RATIONALE: While observing, it is important to write down and photograph as much information as possible.
This will become very important later when we, or our investigating team members, are using our
observations to try to piece together a crime. Documentation is also important when acting as an
expert witness. A judge will only accept hair evidence that has been documented in writing and
with photographs taken at the crime scene. The verbal testimony of a forensic scientist alone may
not be entered into evidence without the proper documentation.
