Which tool is commonly used to develop latent fingerprints at a crime scene?
Fingerprint brush
Scalpel
Tweezers
Laser pointer
A fingerprint brush is used with powder to adhere to the oils left by latent prints, making them visible. Other tools like scalpels or tweezers are not suitable for visualizing fingerprint patterns.
What is the primary purpose of establishing a perimeter around a crime scene?
To interview witnesses
To document witness behavior
To display authority
To preserve evidence
A perimeter prevents unauthorized entry and contamination, ensuring evidence remains intact. Interviewing witnesses or showing authority are not the main goals of securing the scene.
What type of evidence is an eyewitness testimony classified as?
Direct evidence
Biological evidence
Circumstantial evidence
Trace evidence
An eyewitness testimony is direct evidence because it directly relates to what the witness observed. Circumstantial evidence suggests facts indirectly and trace evidence refers to physical particles.
Which record provides the most precise timestamp for a suspect's actions?
Witness memory
Phone call logs
Security guard notes
Victim's journal entry
Phone call logs include exact timestamps recorded automatically by telecom systems, making them precise markers. Witness memory and guard notes rely on human recall, which can be less accurate.
What does the "chain of custody" ensure when handling physical evidence?
Evidence validity through analysis
Secure storage location
Rapid analysis of samples
Evidence continuity without tampering
Chain of custody tracks every person who handles evidence to prevent tampering or contamination. It does not directly speed up analysis or guarantee where samples are stored.
What is the primary purpose of using luminol at a crime scene?
To reveal latent fingerprints
To detect invisible blood traces
To photograph the scene in low light
To measure room temperature
Luminol reacts with the iron in blood to produce chemiluminescence, revealing traces invisible to the naked eye. It is not used for fingerprint development or environmental measurements.
A witness states that the victim was alive at 8:00 PM, but security footage shows the victim on camera at 7:45 PM. This discrepancy is an example of which investigative consideration?
Inconsistency in witness statement
Confirmation bias
Exculpatory evidence
Corroboration of testimony
The mismatch between the witness's claim and the recorded timestamp indicates an inconsistency in the statement. It does not automatically exonerate anyone or demonstrate bias.
In blood spatter analysis, the point where multiple stains converge is known as the:
Tail of stain
Impact pattern
Area of convergence
Cast-off pattern
The area of convergence is where the trajectories of individual blood stains intersect, indicating the two-dimensional location of the source. Impact patterns and cast-off patterns describe different aspects of blood distribution.
Finding fibers on a suspect that match the victim's carpet is an example of:
Alibi evidence
Testimonial evidence
Direct evidence
Class evidence
Class evidence narrows down possibilities to a group, such as a type of carpet fiber. It cannot uniquely identify an individual without additional context.
When assessing a witness's reliability, which factor is most relevant?
Witness's educational background
Witness's relationship status
Witness's height
Consistency of their statements
Consistency across multiple recountings indicates reliability, whereas unrelated personal details do not directly affect credibility. Physical characteristics are irrelevant to statement accuracy.
Deductive reasoning allows a detective to:
Ignore contradictory evidence
Generate broad theories from specific facts
Rely solely on eyewitness accounts
Narrow down suspects by applying general rules
Deductive reasoning applies general premises to specific cases to rule out or confirm suspects. It is not about formulating broad theories from limited facts.
Which evidence type is best described as digital evidence?
A bloody knife
Fiber sample
Eyewitness sketch
Cell tower location logs
Cell tower logs are digital records generated by devices. Physical items like knives and fibers are physical or biological evidence, not digital.
A break in the chain of custody most likely leads to:
Increased sample accuracy
Enhanced data encryption
Faster laboratory processing
Questioned evidence integrity
If the chain of custody is broken, evidence may be considered tampered with or contaminated, casting doubt on its validity. It does not improve processing speed or encryption.
Which investigative technique is used to develop latent fingerprints on non-porous surfaces?
DNA profiling
Cyanoacrylate fuming
Ninhydrin spray
Blood spatter analysis
Cyanoacrylate fuming (superglue fuming) adheres to fingerprint residues on non-porous surfaces, making them visible. Ninhydrin is used on porous surfaces like paper.
Ballistic fingerprinting involves comparing:
Fiber type
Blood types
Hair root shapes
Bullet striations
Bullet striations are unique marks left on bullets by a specific firearm's barrel. These striations can be matched to a suspect weapon.
A witness's recollection changes after being exposed to misleading suggestions. Which memory phenomenon explains this change?
Encoding specificity
Misinformation effect
Confirmation bias
Decay theory
The misinformation effect occurs when post-event information alters a person's memory of the original event. It explains why misleading questions can distort recall.
In blood spatter analysis, if the angle of impact is 30° and the horizontal distance from the stain to the convergence point is 60 cm, what is the approximate height of the blood source?
52 cm
60 cm
40 cm
35 cm
Using the formula height = distance à - tan(angle), height = 60 cm à - tan(30°) ≈ 60 cm à - 0.577 = 34.6 cm, rounded to 35 cm. Other values do not match the trigonometric calculation.
A detective eliminates suspects who lack both motive and opportunity, focusing only on those who have both. Which reasoning method is this?
Inductive reasoning
Conjunctive reasoning
Abductive reasoning
Bayesian inference
Conjunctive reasoning requires that two or more conditions (motive AND opportunity) be true simultaneously. It narrows suspects by applying both criteria together.
Integrating physical, digital, and testimonial evidence to draw conclusions is known as:
Sequential interviewing
Linear reasoning
Profiling synthesis
Data triangulation
Data triangulation involves combining multiple types of evidence to corroborate findings and strengthen conclusions. Sequential interviewing and profiling synthesis are different methods.
Which investigative principle states that every contact leaves a trace?
Corpus delicti
Occam's razor
Locard's exchange principle
Frye standard
Locard's exchange principle holds that offenders both bring something into and take something away from a crime scene. It underpins trace evidence analysis.
