What is forensic science?
The study of crime scenes.
The study of insects.
The building of body farms.
The application of science to those criminal and civil laws that are enforced by police agencies in a criminal justice system.
Who is Mathieu Orfila?
Used a comparison microscope to determine if a bullet was fired from a specific gun
Conducted the first definitive study of fingerprints and their classification
Father of Forensic Toxicology
Popularized physical detection methods in a crime scene
Who is Edmond Locard?
Was responsible for the acceptance of documents as scientific evidence by the courts
Stated that once contact is made between two surfaces a transfer of material(s) will occur
What does (OIC) stand for?
Original incident cover
Optional Incident Container
Officer in common
Officer in charge
Who should have access to a crime scene?
District attorney so he/she can build a criminal case
Only those people responsible for the immediate investigation of the crime, the securing of the crime scene, and the processing of the crime scene should be present
Immediate family members
Anyone who is interested, including news reporters
Select 3 things used to record a crime scene?
Sketches
Friends
Photographs
Detailed notes
Word of mouth
A rough sketch should include which of the following 5 things?
Location of objects by use of measurements
The possible location of where the perpetrator was
Identification of all items by use of identifying numbers or letters which match with the investigator’s evidence property log.
Where the Officer in Charge and other personnel are standing
All other important items of the crime scene
All recovered items of physical evidence
An overall view including the relationship of items to each other
Any additional furniture that would make the house look better
What is Locard's Principle?
Holds that the perpetrator of a crime will bring something into the crime scene and leave with something from it, and that both can be used as forensic evidence
Holds that increasing the amount of detective stories will increase funding to Forensic Science research
States that the exact bullet fired can be matched through striations to the original firing gun
Proves that using DNA Fingerprinting, we can match the exact perpetrator to the crime
What are the 5 basics of crime scene processing?
Put the scene on Instragram so witnesses will come forward
Interview witnesses
Discuss with friends and family
Examine
Sketch
Process
Describe to reporters
Photograph
What are the five basics of death?
Time
Temperature
Meaning
Location
Manner
Cause
Mechanism
What does (MOD) stand for?
Manner of Death
Mechanism of Death
Meaning of Death
Cause of Death
The specific body change that brought about cessation of life
The following are symptoms of what: * RBC break down & spill contents * Hemoglobin turns purple when it spills * Purplish color visible wherever blood pools (lividity)
Livor Mortis
Algor Mortis
Rigor Mortis
Nothing
The use of the insects and other arthropods that feed on decaying remains to aid legal investigations, is known as:
Insectology
Entomology
Forensic Science
Crime Scene Investigation
What are the two major insects used in entomology?
Flies and Beetles
Worms and Maggots
Spiders and Flies
Stink Bugs and Roaches
What is Postmortem Interval (PMI)?
The amount of time a corpse was in a freezer
The time between when the body was attacked and when it died
The time between corpse discovery and delivery to the morgue
The time between death and corpse discovery
Forensic Entomology can be used to determine all of the following, except:
Postmortem Interval (PMI)
If the corpse was moved
Manner and Cause of Death
Association of Suspects with the Death Scene
Detection of toxins, drugs, or even the DNA of the victim through analysis of insect larvae.
How long a corpse was stored in a freezer
A forensic entomologist does all of the following, except:
Calculates the growth of the insects and passage through stages of the life cycle in laboratory
Identifies the immature insects
Compares the growth against weather conditions to estimate time of oviposition
Interviews witnesses
Determines the size and development of the insects
All of the following are part of the 5 Stages of Decomposition Fueled by Insect Activity, except:
Bloat
Fresh
Frozen
Decay
Dry (skeletal)
Post-decay
Finding a corpse in the woods that was kept in a freezer for some time would alter the Time of Death from the PMI (Post-Mortem Interval).
The Post Mortem Interval is restricted to the time that the corpse or body has been exposed to an environment which would allow insect activity to begin.
A corpse swells due to gases produced by bacteria during the Fresh Stage of Decomposition.
What stage is this?
Temperature, access by insects and the depth of burial can all affect the Rate of Decay.
A body was found with rigor present in the legs, but no rigor in the upper torso. What is the ToD?
2 to 6 hours
12 hours
15 to 36 hours
36 to 48 hours
Calculating the ToD (Time of Death) by the amount of heat lost by the corpse, is known as:
Heat Indexing
