FIS 201 – Final Exam Study Guide and Practice Questions
Cause of death - ANS✔✔ bullet wound, head wound, strangulation, etc.
Manner of death - ANS✔✔ Natural, Accidental, Homicide, Suicide, Undetermined.
Warrant exceptions - ANS✔✔ consent, exigent circumstances, plain view, stop and frisk,
incident to arrest, open fields, abandoned property, vehicle, custodial, border, administrative,
probation search, protective sweep
GCMS - ANS✔✔ Used by toxicologist to separate the GC, and then identify the mixture
components based on how they break up in ionization.
-GC does the separation
-MS gives us our results
SEM - ANS✔✔ -Locates particles of gunshot residue
TLC - ANS✔✔ Used for the comparison of drugs, explosives, inks, and dyes
Comparison microscope - ANS✔✔ -All microscopic evidence requiring visual comparison
-Compares bullets
Immunoassay - ANS✔✔ -Determines if the blood is human
-Presumptive test for blood, semen, saliva, and urine
PCR & Electrophoresis - ANS✔✔ -PCR: Technique to exponentially copy DNA fragments
, -Electrophoresis: uses agarose gel to sort chunks of DNA and electricity to power their
movement
STR/YSTR/mtDNA - ANS✔✔ STR: highly variable number of repeats in a population
YSTR: nucleus, 11-17 locie w/STRs, passed father to son
mtDNA: inherited from mom, shows family relationship, 1-1000/ cell, circular DNA
Spectrophotometer - ANS✔✔ -Looks at the chemical composition and color and dye
information of fibers
-Measures the amount of light reflected at precise wavelengths
-Moderatley selective for chemistry of pigments and binders of paints
How can contamination at a crime scene be prevented? - ANS✔✔ hazmat suit, tyvek coveralls,
goggles, mask ,gloves, shoe covers
Mechanical trauma - ANS✔✔ physical actions
Electrical trauma - ANS✔✔ Electrical conduction through the body
