Ch. 2 - Crew of the Starship CSI
Commonly referred to as the "Father of Forensics", this man created a principle that states when two people come into contact, physical transfer occurs
Who is Dr. Edmond Locard?
When a body is decomposing, CSI members may look for this common insect to be present in one of its 6 stages, as means for determining the TOD (Time of Death)
What is the Blowfly?
Every human being has these on their fingers that enable them to grasp/hold things, but also leaves a fingerprint behind on something we've touched
What are Ridges?
What is Deoxyribonucleic Acid?
What is A, B, AB, and O?
The extent of the physical transfer depends on these 3 variables
What are the 1) Intensity, 2) Duration, and 3) Nature of the Contact?
The title of a person who studies insects and interprets insect evidence is called this
What is a Forensic Entomologist?
What are 1) Loops, 2) Whirls, and 3) Arches?
The 4 types of nucleotides found in DNA are these
What are 1) Thymine, 2) Cytosine, 3) Adenine, and 4) Guanine?
The Universal Donor and Universal Recipient blood types are these
What are O- (donor) and AB+ (recipient)?
A type of evidence that implies a fact but does not prove it
What is Circumstantial Evidence?
After observing the chickens in the Colonia Courtyard of Death, it was evident that these factors may contribute to the development or delayed development of the blowfly in its various stages...hopefully you'll know at least 3!
What are 1) Ambient environmental factors, 2) Clothing, 3) Temperature, 4) Time of Day, 5) Exposure to Environment, or 6)Exposure to Toxins, Chemicals, Drugs?
The individuality of a fingerprint is not determined by it’s general classification, but by careful study of its ridge characteristics, known as these
What are Minutiae Patterns?
This professor is credited with developing the process of DNA profiling
Who is Alec Jeffreys?
Blood drops falling by gravity alone are considered this
What are Passive Drops?
The very first step of the CSI process is to do this
What is Secure the Scene?
These 5 stages of decomposition can be determined by the types of insects forensic investigators observe on/around the body during an investigation
What is 1) Fresh, 2) Bloated, 3) Active Decay, 4) Advanced Decay, and 5) Dry/Skeletal Decay?
Investigators may look for this number of common minutiae patterns during a fingerprint analysis
What is 10?
Although there are exceptions, most human beings have this many chromosomes, sharing 50% from a mother and 50% from a father
What are 46 chromosomes?
Blood stains can be classified by these 3 speeds
What are Low Velocity, Medium Velocity, and High Velocity?
These are 4 search patterns crime scene investigators use to complete the 6th step of the CSI process
What is 1) Spiral, 2) Grid, 3) Line/Strip, and 4) Quadrant?
Investigators can use these respiratory organs of larvae to identify what stage of growth the larvae is currently in
What are Spiracles?
The 3 types of fingerprints that may be left behind at a crime scene are these
What are 1) Visible Prints, 2) Plastic Prints, and 3) Latent Prints?
A visual representation of an individual's complete set of chromosomes, arranged by size, shape, and number
What is a Karyotype?
Directionality can be determined by this part of the bloodstain
What is the Tail?
