Q

forensic anthro from 1940-1970

A
  • > WW2, Korean and Vietnam wars left alot of bodies that needed to be identified
  • > alot of age based observation as they were mostly white males
  • > discipline was legitimized and there were increased method development

Q

forensic anthro 1970-1990s

A
  • > increased professionalization, American Academy of Forensic Anthropology
  • > renaissance of human skeletal biology
    1. Modern comparative samples
    2. better analytical stats to interpret variation

Q

describe new brunswicks coroner services

A
  • > independent and publicly accountable investigation of death agency
  • > they determine the identity of all reported deaths in NB and how, when, where and by what means they died
  • > deal with all deaths that are unnatural, unexpected, unexplained or unattended
  • > responsible for determining whether such reported deaths are related to natural causes, accident, suicided, or homicide

  • > violence
  • > misadventure or negligence
  • > misconduct or malpractice
  • > during pregnancy or following pregnancy in circumstances that might reasonably be attributable to the pregnancy*
  • > suddenly and unexpectedly
  • > from disease or sickness for which there was no treatment given by a medical practitioner

Q

perimortem

A
  • > events surrounding death
  • > any disease, trauma, illness that initiates the sequence of events leading to death
  • Brief - gunshot; long - chronic illness
  • > concludes at the end of interaction between individual and causative agent (not nessarily death)

16
Q

cause of death vs manner of death

A

COD
- > disease or injury responsible for initiating the sequence of events, brief or prolonged, that result in death
MOD
- > the fashion in which the cause of death came into being.

17
Q

What are the 5 recognized manners of death

A
  1. Natural
    - > resulting exclusively from disease or advanced age
  2. Accidental
    - > trauma or elevated toxicity causing or contributing to death, harm inflicted not intentional (i.e. car crash, falls, drowning, OD)
  3. Suicide
    - > intentional killing of oneself
  4. Homicides
    - > death at the hands of another
  5. undetermined
    - > when manner of death is elusive
18
Q

medicolegal significance; how is significance determined

A
  1. is the material skeletal vs other material
  2. Is the skeletal material human vs non-human
  3. is the human skeletal material contemporary vs non-contemporary (historic/prehistoric)
19
Q

Contemporary vs non-contemporary

A
  • > 50 years (1970s) for forensic

- > cannon establish ID, legal challenges, lack of data

20
Q

what to look for to determine if the remains are contemp vs non contemp

A
  • > whether soft tissue is present
  • > appearance and quality of preservation
  • > postmortem treatment: embalming, autopsy evidence, processing chemicals
  • > location and context of remains
  • > presence of artifacts/grave goods
  • > body modifications (i.e. dental and medical devices)
21
Q

describe skeletal examinations

A
  • > all methods have inherent limitation (measuring bones by hand has deviation)
  • > assessments/determination: observing morphological traits (categorical/discrete data) i.e. sex determination
  • > estimations: observing metric traits (continuous data) i.e. age determination
22
Q

examples of macroscopic assessments

A
  • > inventory of remains
  • > condition of remains
  • > estimation of age, sex, pathology and trauma-biological profile
  • > degree of expression and overall morphology
  • > presence vs absence
  • > limitations: subjective, less standardized, bias, experience and training requirements
23
Q

metric assessments

A
  • > skeletal measurements = osteometrics
  • > variation difficult to detect
  • > used in calculation - i.e. stature
  • > statistica power, elimination of error, requires training (landmark ident.), how to calculate and interpret data
24
Q

radiography assessments

A
  • > documentation, detection and diagnosis
  • > detects foreign materials (i.e. ballistics)
  • > shows internal structures (sinuses, dentition) and changes to bone (implants, pathology)
25
Q

describe case documentation in a medicolegal context

A
  1. Authentication
    - > multiple pros sign off on the data
  2. Verification
  3. Traceability
    - > we know where all the evidence is at any given time
26
Q

3 governing rules of evidence

A
  1. Federal rules of evidence 702
  2. Frye ruling
  3. daubert ruling
    - > Mohan ruling - Canada
27
Q

Mohan ruling

A
  • > to be admitted expert evidence must:
    1. be relevant
    2. be needed to assist the trier of fact
    3. not trigger any exclusionary rules
    4. be given by a properly qualified expert
28
Q

requirements to be an expert witness

A
  • > strict rules for qualification as “expert”
  • > usually PhD minimum
  • > can offer opinion based on experience or experiential findings
  • > sufficient knowledge, skill, experience, training, or education to assist with understanding evidence
