Forensic Anthropology is
  • The application of anthropological techniques to
    modern human remains for law enforcement.
  • In general, the forensic anthropologist provides
    a basic biological profile to aid in
    identification of the decedent.
  • Your textbook uss the definition of skeletal
    remains resulting from unexplained deaths. Why
    would this be incorrect?

3
The ten questions (Ive added to the original
ten codified by Snow (1982). My additions are in
red).
  • Is it bone?
  • Is it human?
  • Is it of forensic value?
  • What bones are present?
  • What is the MNI?
  • What is the sex?
  • What is the age?
  • What is the ancestry?
  • What is the height?
  • Are there any anatomical anomalies, pathologies,
    etc.?
  • Are there any indicators of behavior?
  • What is the PMI?
  • Evidence for cause of death?
  • Evidence for manner of death?

4
Five Main Objectives
  • Ancestry, age, sex, and height
  • Trauma information to determine cause and manner
  • Postmortem interval
  • Locating and recovering buried or surface remains
  • Positive identification

5
History
  • Thomas Dwight (1843-1911)
  • Father of Forensic Anthropology in the United
    States
  • Wrote articles and essays and lectured on human
    skeletal identification
  • Researched determination of height, sex, stature,
    age at death

6
Formative Period
  • Early 1800s to 1938
  • Parkman murder of 1849
  • Oliver Wendell Holmes I and Jeffries Wyman
  • Leutgert case of 1897
  • George Dorsey
  • Harris Wilder, Bert Wentworth, Paul Stevenson,
    Ales Hrdlicka, Earnest Hooton, T. Wingate Todd,
    Robert Terry

7
Consolidation Period
  • 1939-1971
  • Began with publication of Guide to the
    Identification of Human Skeletal Material by
    Krogman
  • Written for the FBI
  • WWII dead were badly decomposed, but needed to be
    identified, so CILHI was established
  • Korean War dead, new CIL in Japan, several
    studies and publications
  • Research in depth on military dead

8
Modern Period
  • 1972 to present
  • Establishment of the Physical Anthropology
    Section of the American Academy of Forensic
    Sciences in 1972
  • American Board of Forensic Anthropology created
    in 1977
  • Forensic Anthropology Data Bank at UT Knoxville

9
Data Gathering Methods
  • Anthroposcopy Visual inspection of the human
    body
  • Osteometry measurement of human bone
  • Chemical methods
  • Histology study of the microstructure of bone
    and teeth

10
  • Decision table helps researchers judge the
    relative importance of information
  • Range chart uses multiple ranges of estimates so
    a central tendency can be determined
  • Indexes use numerical expressions of shape to
    compare between groups
  • Discriminant functions calculate a numerical
    expression of shape
  • Regression uses one value to determine another

11
Forensic Anthropology in LA
  • Six basic types of cases on which I work
  • Human vs. Non-human identification
  • Wet Cases
  • Decedent Searches
  • Skeletal Remains/Surface Field Recovery
  • Buried Body Recovery
  • Burned Body Recovery

12
For The Other Types of Cases
  • Decedent Searches
  • Skeletal Remains/Surface Field Recovery
  • Buried Body Recovery
  • Burned Body Recovery
  • There is SORT, the Special Operations Response
    Team

13
The Special Operations Response Team
  • SORT founded in 2001
  • SORT grew out of the former Los Angeles County
    Coroner Disaster Response Team (DRT), which was
    started in 1996
  • DRT covered only mass fatalities
  • All members of DRT were also members of the
    federal Disaster Mortuary Operational Response
    Team (DMORT)
  • Because of the large number of special cases
    the DRT was expanded into the present SORT

14
SORT
15
SORT
  • Mass Fatality Incidents
  • Multiple Decedent Assistance
  • Special Decedent Recovery (includes burned
    bodies)
  • Buried Body Recovery
  • Decedent Searches
  • Public Relations Events

16
Investigations
  • Traditionally one Coroner Field Investigator was
    assigned per call regardless of the type of case
    or number of fatalities involved.
  • The Investigator on cases involving specialized
    resources was forced to rely on other agencies
    personnel, equipment, and resources, and
    therefore often lost control of the crime scene
    and lost decision making power as the other
    agencies moved in to assist in the processing of
    the scene.
  • SORT provides all necessary equipment and
    personnel to the Investigator.

17
Criminalistics
  • SORT provides skilled manual labor available 24
    hours a day to assist the Criminalist, with team
    members able to recognize items of potential
    evidential value and thereby prevent accidental
    contamination of a scene by support staff.
  • In addition, the pre-organized SORT allows for
    efficiency in processing a scene.

18
Pathology
  • From the pathologist's perspective, the
    importance of a team such as SORT is twofold
  • The team will effectively document the recovery
    and the scene
  • The pathologist knows the team understands
    his/her requirements and preferences and will
    maximize the evidence collected to be used in
    his/her efforts

19
Anthropology
  • The main concern of the Archaeologist in the
    field is total recovery of the decedent, no
    matter how scattered, total recovery of artifacts
    associated with the decedent, and total recovery
    of associated evidence.
  • SORT allows the Archaeologist more flexibility in
    applying archaeological methods and techniques to
    the scene.

20
  • The Anthropologist requires remains as complete
    as possible to construct a biological profile and
    aid in positive identification of the decedent.
  • Knowing that a specially-trained team is
    performing the recovery allows these consultants
    to concentrate on their jobs, not on what
    everyone else is doing.
  • The trust engendered allows a recovery to proceed
    at a fast pace without the consultants constantly
    having to check the efforts of other personnel.

21
Problem Cases Prior to SORT
  • Buried body recovery, decedent searches, and
    recovery under special circumstances were
    especially difficult prior to SORT.
  • Without the proper personnel or equipment, ready
    on short notice, personnel present at scene must
    take on tasks for which they may not have proper
    training, or for which they are unprepared.

22
Outside Agencies
  • Even after the formation of SORT, but prior to
    wide publication of its existence, outside
    agencies often assumed and/or maintained control
    of scenes in which a body was found.
  • Such circumstances made complete recovery and
    identification of decedents more difficult for
    Coroner personnel.
