Differences between time frame of fractures: - ANS✔✔ Antemortem: An injury that occurs
before death with evidence of healing (reformed bone with round, smooth edges)
Perimortem: An injury that occurs at or around the time of death when a bone is still green or
fresh (sharp, clean edges), with no evidence of healing
Postmortem: An injury that occurs after death, when a bone is dry and brittle (jagged edges,
random pattern), with no evidence of healing

3. more of a square jaw
Asian skull characteristics: - ANS✔✔ 1. circular eye orbits prominenet prognathism
2. more of a rounded jaw bone
European skull characteristics: - ANS✔✔ 1. sometimes v-shaped jaw, typically square-ish
2. rectangular "aviator-shaped" eye orbits
3. high projecting nasal bone
What is the hardest material in the body? - ANS✔✔ enamel

test which indicates the presence of a compound of interest. Has
High sensitivity, moderate selectivity. Says that the material should be examined further -
ANS✔✔ Presumptive test:
, test or tests which positively identify the material
Moderate sensitivity, high selectivity - ANS✔✔ Confirmatory test
Presumptive Testing Methods: - ANS✔✔ Samples the stain: swab or filter paper
Apply the reagents
Document results
Kastle-Meyer test/Phenolphthalein Test: - ANS✔✔ MOST COMMON IDENTIFICATION TEST FOR
BLOOD
Use on visible stains:
- Phenolphthalein in an alkaline solution
- Add peroxide plus the iron from hemoglobin
Pink swab means positive
No color means negative
Leucomalachite green test - ANS✔✔ Use on visible stains:
- Positive test turns the swab green
- Add hydrogen peroxide to reagent + hemoglobin
Leucocrystal Violet (LCV) - ANS✔✔ Use on low visibility stains for enhancement
Has a good amount of false positives
Reacts with hemoglobin to turn purple/black
Tests a large area instead of an individual stain
Luminous tests - ANS✔✔ Use for detection
