Week 2 - Introduction to Forensic Anthropology Flashcards
what is forensic anthropology
- > branch of biological anthro concerned with the identification and recovery of human SKELETAL remains in a legal context using anthological methods and theories
forensic anthro pre 1940s
- > anatomists, physiologists were self taught, had informal training
- > little medicolegal significance
forensic anthro from 1940-1970
- > 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
forensic anthro 1970-1990s
- > increased professionalization, American Academy of Forensic Anthropology
- > renaissance of human skeletal biology
1. Modern comparative samples
2. better analytical stats to interpret variation
forensic anthro 1990-present
- > a lot more accessible; there are now university programs and databases for the discipline
- > best practices guidelines and standards used in the discipline and in courts
medicolegal
the application of medical science to law
medicolegal system
- > system head is either a coroner or a medical examiner who is responsible for determining cause and manner of death
- > formal mechanism for death investigation and certification within a specific geographic area
coroner
- > elected or appointed
- > does not need to be a physician
- > does not need to attend or perform autopsies
- > i.e. physician, law enforcement officer, funeral director
medical examiner
- > appointed by public official
- > licensed, board-certified forensic pathologist
- > perform autopsies
- > convene inquests
describe new brunswicks coroner services
- > 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
What warrants a medicolegal investigation in NB
• If a person has died as a result of
- > 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
- > from any cause other than disease or natural causes!!!!!!
What are the 3 time classification of death
- Perimortem
- Antemortem
- Postmortem
perimortem
- > 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)
antemortem
- > begins at birth and ends at the perimortem period
postmortem
begins at the end of perimortem and continues until the body is discovered
cause of death vs manner of death
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.
What are the 5 recognized manners of death
- Natural
- > resulting exclusively from disease or advanced age - Accidental
- > trauma or elevated toxicity causing or contributing to death, harm inflicted not intentional (i.e. car crash, falls, drowning, OD) - Suicide
- > intentional killing of oneself - Homicides
- > death at the hands of another - undetermined
- > when manner of death is elusive
medicolegal significance; how is significance determined
- is the material skeletal vs other material
- Is the skeletal material human vs non-human
- is the human skeletal material contemporary vs non-contemporary (historic/prehistoric)
Contemporary vs non-contemporary
- > 50 years (1970s) for forensic
- > cannon establish ID, legal challenges, lack of data
what to look for to determine if the remains are contemp vs non contemp
- > 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)
describe skeletal examinations
- > 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
examples of macroscopic assessments
- > 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
metric assessments
- > 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
radiography assessments
- > documentation, detection and diagnosis
- > detects foreign materials (i.e. ballistics)
- > shows internal structures (sinuses, dentition) and changes to bone (implants, pathology)
