100
This is the second most common type of fingerprint pattern
What is a whorl?
100
A chemical that glows as it reacts with bioorganic substances, which is found in blood
What is luminol?
100
It is measured by 1g of alcohol per 100 mL of blood in the US
What is Blood Alcohol Concentration?
100
Requires ingestion of a large amount of substance to be lethal.
What is an Intoxicant?
100
The diameter of a given projectile, which is measured at its widest point, and is recorded in hundredths of an inch or millimeters.
What is caliber?
200
This is the point on a friction ridge at or nearest to the point of divergence of two type lines (resembles a Greek letter)
What is the delta?
200
A positive test for blood will glow yellow under this light
What is blacklight (ultraviolet light)?
200
This BAC testing device was invented by Richard Harte in 1977 and used IR to analyze BAC.
What is the Intoxilyzer?
200
This poison is one of the few that visibly changes the external body and can be identified before fluid and tissue samples are examined.
What is Arsenic?
200
The study of how a projectile behaves when it hits its target and transfers its kinetic energy to the target. (Hornady Manufacturing Glossary)
What is terminal ballistics?
300
The method for developing fingerprints, performed in a chamber to allow vapors to adhere to prints and make them visible- prints can later be enhanced with powder
What is cyanoacrylate (super glue) fuming?
300
A chemical indicator that suggests a negative test for blood if it changes color in reaction to sample
What is phenolphthalein?
300
This Indiana University professor created the original Breathlyzer in 1954.
Who is Robert Borkenstein?
300
The drug found in the body that typically indicates heroin usage.
What is morphine?
300
These two phenomenon decrease as the distance of the bullet from the barrel increases, and are often used to measure and describe the circular movement of the tip of a projectile, as well as the projectile itself, around a specific axis.
What is yaw and precession?
400
A type of print impression secreted in a surface or on an object, usually invisible to the naked eye.
What is a latent print?
400
This is mathematically determined by dividing the width of a blood stain by the length (sine) and converted to degrees
What is the angle of impact?
400
A reaction where reduction (gain of electrons or hydrogen and loss of oxygen) and oxidation (loss of electrons or hydrogen and gain of oxygen) occurs
What is a redox reaction?
400
This poison was ingested by the Greek philosopher Socrates.
What is Hemlock?
400
The spiral groves added to a gun barrel to increase gyroscopic stability?
What is rifling?
500
Proposed the hypothesis that no two fingerprints are identical and that fingerprints are not inherited.
Who is Francis Galton?
500
This test uses phenolphthalein and hydrogen peroxide to detect the possible presence of blood, and a swab rubbed on a sample will turn bright pink if the test is positive- however, this test often yields false positives.
What is the Kastle-Meyer test?
500
The de jure BAC Limit of Portugal.
What is 1 g alcohol/1 L blood?
500
This was used to poisonl Heather Chandler in the 1980s.
What is Ethylene glycol (antifreeze)?
500
The average velocity range of a predominant handgun-produced projectile (.22 lr-.45 ACP)
What is 650 FPS-1,500 FPS?
