Case Studies
Cause of death - correct answer ✔✔bullet wound, head wound, strangulation, etc.
Manner of death - correct answer ✔✔Natural, Accidental, Homicide, Suicide, Undetermined.
Warrant exceptions - correct answer ✔✔consent, exigent circumstances, plain view, stop and
frisk, incident to arrest, open fields, abandoned property, vehicle, custodial, border,
administrative, probation search, protective sweep
GCMS - correct answer ✔✔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 - correct answer ✔✔-Locates particles of gunshot residue
TLC - correct answer ✔✔Used for the comparison of drugs, explosives, inks, and dyes
Comparison microscope - correct answer ✔✔-All microscopic evidence requiring visual
comparison
-Compares bullets
Immunoassay - correct answer ✔✔-Determines if the blood is human
-Presumptive test for blood, semen, saliva, and urine
, PCR & Electrophoresis - correct answer ✔✔-PCR: Technique to exponentially copy DNA
fragments

YSTR: nucleus, 11-17 locie w/STRs, passed father to son
mtDNA: inherited from mom, shows family relationship, 1-1000/ cell, circular DNA
Spectrophotometer - correct answer ✔✔-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? - correct answer ✔✔hazmat suit, tyvek
coveralls, goggles, mask ,gloves, shoe covers
