Which motive behind a murder is characterized by anger and betrayal?
Jealousy
Greed
Self-defense
Revenge
Revenge is driven by feelings of anger and betrayal against the victim, distinguishing it from motives like greed or jealousy. It often involves a desire to retaliate for perceived wrongs.
What is an alibi in the context of a criminal investigation?
Suspect's statement placing them elsewhere
Suspect's confession
Evidence found at the scene
An official search warrant
An alibi is the suspect's claim or evidence that they were in a different location when the crime occurred. Verifying this helps investigators confirm whether the suspect could have committed the offense.
Blood drops larger than 4 millimeters in diameter at a crime scene are classified as which type of spatter?
Low-velocity spatter
High-velocity spatter
Mist spatter
Medium-velocity spatter
Low-velocity spatter produces larger drops, typically over 4 mm, due to gravity being the primary force. Higher velocity impacts generate much finer mist or medium-sized droplets.
Which fingerprint pattern is the most common in forensic investigations?
Whorl
Tented arch
Loop
Arch
Loop patterns appear in about 60 - 65% of fingerprints, making them the most common classification. Whorls and arches occur less frequently, with tented arches being the rarest.
Rigor mortis refers to what postmortem phenomenon?
Pooling of blood
Breakdown of tissues
Stiffening of the muscles
Cooling of the body
Rigor mortis is the stiffening of muscles that begins a few hours after death due to chemical changes in muscle fibers. It continues for about 24 - 48 hours before dissipating.
Which term describes the cooling of the body to match ambient temperature after death?
Decomposition
Lividity
Rigor mortis
Algor mortis
Algor mortis refers to the gradual cooling of the body until it reaches the surrounding environmental temperature. Investigators use this to estimate time of death alongside other factors.
Which investigative method is most useful for verifying a suspect's alibi by checking the sequence of events?
Timeline construction
Fingerprinting
DNA analysis
Ballistic analysis
Constructing a timeline allows investigators to map out each event and check for inconsistencies in a suspect's story. It helps pinpoint where and when the suspect could or could not have been present.
What type of wound is created by a sharp-edged object such as a knife?
Thermal burn
Blunt force abrasion
Projectile wound
Sharp force injury
Sharp force injuries result from objects with a defined cutting edge or point, producing clean incised wounds. Blunt force injuries, by contrast, cause crushing or tearing rather than clean cuts.
In a staged suicide, which clue most strongly suggests homicide rather than self-inflicted death?
Single clean incision to the wrist
Weapon found at an unnatural distance from the body
Presence of a handwritten suicide note
Absence of defensive wounds
When the weapon is placed unrealistically far from the victim's hand, it suggests someone else positioned it to appear suicidal. Genuine self-inflicted wounds usually keep the weapon close at hand.
Which tool helps detect invisible ink at a crime scene?
Metal probe
Thermal imaging camera
Ultraviolet lamp
Metal detector
Ultraviolet light causes certain inks and substances to fluoresce, revealing hidden or invisible writing on documents. Other tools do not produce the specific light frequency needed.
Based on the statements below, who committed the crime? A: "B is guilty." B: "C is innocent." C: "B is lying." Only one statement is true.
B
A
No one
C
If C is guilty, then A's statement ("B is guilty") is false and B's statement ("C is innocent") is false. C's statement ("B is lying") is then true, satisfying exactly one true statement.
Which type of motive is characterized by obtaining money or property?
Instrumental motive
Passionate motive
Expressive motive
Vindictive motive
Instrumental motives involve using a crime as a means to achieve a tangible goal such as financial gain. This differs from emotional or expressive motivations.
Which term refers to the settling of blood in dependent areas of the body after circulation stops?
Decomposition
Algor mortis
Rigor mortis
Lividity
Lividity (or livor mortis) is the gravitational pooling of blood in the lowest-lying tissues after death. It helps investigators estimate body position and time since death.
Which of the following is considered trace evidence due to its microscopic nature?
Textile fibers
Ballistic trajectory
Blood spatter
Fingerprints
Textile fibers are classed as trace evidence because even tiny fragments can link a suspect or object to a crime scene. Fingerprints and blood spatter are not classified as trace evidence.
Which technique is primarily used to enhance low-quality surveillance footage?
Luminol spray
Latent fingerprint development
Ballistic comparison
Digital image processing
Digital image processing algorithms can sharpen, increase contrast, and reduce noise in video frames to reveal important details. Other methods do not apply to video enhancement.
Investigators discover ladder rung impressions on the wall beneath a second-floor window. What is the most logical inference?
The ladder was decorative
An intruder climbed from the ground using a ladder
The victim escaped through the window
The window was never opened
Ladder rung impressions directly under the window indicate someone leaned or placed a ladder there to gain entry. Decorative ladders would not leave such distinct marks at that specific height.
Using an estimated cooling rate of 1.5°C per hour, if a victim's body temperature has dropped from 37°C to 28°C in a room at 20°C, approximately how many hours have passed since death?
10 hours
6 hours
8 hours
4 hours
The body has cooled by 9°C (from 37°C to 28°C). At a rate of 1.5°C per hour, dividing 9°C by 1.5°C/h yields approximately 6 hours since death.
Analyzing microscopic paint chips found on a victim's clothing is an example of which forensic strategy?
Behavioral profiling
Ballistic analysis
Trace evidence analysis
Forensic entomology
Microscopic fragments like paint chips are trace evidence and are examined to link objects or suspects to a scene. Behavioral profiling and entomology address different aspects of investigations.
Which method is most effective for revealing indented writing on an erased notepad sheet?
Electrostatic detection apparatus (ESDA)
Ultraviolet light examination
Thin-layer chromatography
Oblique lighting
ESDA uses electrostatic charges to lift indentations from the paper surface, making previously erased text visible. Other methods cannot reliably reveal indented writing.
Which conclusion can be drawn if a suspect's phone made a call on a cell tower near the crime scene at 10:03 pm, contradicting their claim of being home at that time?
The phone's location cannot be trusted
The phone may have been stolen
The suspect's phone places them near the scene
Call times are always inaccurate
Cell tower connections provide reliable spatial data showing the phone's approximate location. A call on a tower near the crime scene strongly suggests the suspect (or at least their phone) was there.
