    Study Notes

    Francisco Pizarro

    • Francisco Pizarro was a Spanish conquistador who conquered the Inca Empire in the 16th century.
    • He was born in 1475 and died in 1541.

    Forensic Anthropology

    • Forensic anthropology is the application of anthropological knowledge to legal investigations.
    • Forensic anthropologists analyze human skeletal remains to identify individuals, determine the cause of death, and estimate the time since death.
    • The Mochica culture flourished in Peru from 0 to 700 CE.
    • Little historical documentation exists for individuals from the Mochica culture.
    • Forensic anthropologists can uncover mass murders and deaths from the past.

    Thomas Dwight

    • Thomas Dwight (1843-1911) is considered the "father" of forensic anthropology.
    • He published a paper on identifying the sex of a skeleton based on skeletal characteristics.
    • His findings were never used in a court of law.

    The Formative Period (1800s-1938)

    • The Parkman Murder and the conviction of John Webster (1849) was one of the first cases to utilize forensic anthropology.
    • Body parts were found in John Webster's office.
    • Harvard biologists reassembled the body, using teeth to identify the victim, Parkman.
    • This case marked the first use of forensic odontology in a criminal investigation.
    • The case of Adolph and Louisa Leutgert (1897) involved the disappearance of Louisa, the wife of a wealthy sausage factory owner.
    • Three small bones were found in a tank of jelly-like substance in the factory, suggesting foul play.
    • In the Buck Ruxton Case (1938), a foul odor emanating from Buck Ruxton's house led to the discovery of two bodies in a ditch.
    • The bodies were carefully pieced together using photographs.

    The Consolidation Period (1939-1971)

    • Guild to the Identification of Human Skeletal Material by Wilton Marion Krogman (1939) was a significant publication that brought the field to the attention of law enforcement, particularly the FBI.
    • The book encouraged law enforcement to utilize skeletal remains in murder investigations.
    • The Human Skeleton in Forensic Medicine by Wilton Marion Krogman (1962) further popularized forensic anthropology and its applications.
    • The Central Identification Laboratory in Hawaii was established after World War II by Charles Snow (1947) to identify the remains of soldiers.
    • This laboratory played a critical role in developing methods and techniques used in forensic anthropology today
    • The laboratory focused on:
      • Establishing if a grave had been disturbed or if the body had been buried more than once.
      • Determining the cause of death.
      • Identifying the manner of death.
      • Identifying the perpetrator(s).

    Data Gathering Methods

    • Anthroposcopy:
      • This method involves examining physical characteristics of the skeleton that cannot be measured numerically, such as size, shape, and texture.
    • Osteometry:
      • Osteology: The study of bones, including their development, structure, function, and variations.
      • Osteometry: The measurement of human bones using objective scales (usually in millimeters), calipers, and an osteometric board.
    • Chemical Methods:
      • These methods measure the chemical composition of bones.
      • They can be used to identify poisons, reconstruct diet, and determine the health of individuals.
      • These methods are expensive and complex.
    • Histology:
      • involves microscopically examining thin slices of bones and teeth.
      • This method helps determine the age of an individual.

    Data Analysis Methods

    • Decision Tables:
      • These tables help organize evidence and draw conclusions.
    • Range Charts:
      • Range charts combine various sources of information to create a single estimate or conclusion.
    • Indexes:
      • Indexes are calculated by dividing one measurement by another and multiplying by 100.
      • They are useful for visualizing identifiable characteristics.
      • For example, the nasal index is calculated by dividing the nasal width by the nasal height and multiplying by 100.
      • Nasal indexes indicate ancestral background:

        • 85% = African Ancestry

        • < 70% = Caucasian Ancestry

    Human Osteology

    • Osteology is the study of bones, including their development, structure, function, and variations.
    • It is essential to forensic anthropology for:
      • Identifying and analyzing skeletal remains at archaeological sites.
    • Practical applications of osteology:
      • Determining a living person's physical characteristics (ancestry, age, sex)
      • Evaluating the health of a person
      • Identifying habitual activities
      • Identifying a deceased person
      • Recognizing the cause and manner of death
      • Determining the approximate time since death
      • Gathering information about post-mortem events (animal scavenging, dismemberment, etc.)

    Function of Bones

    • Bones serve various functions:
      • Support: Bones provide structural support for soft tissues and muscles.
      • Protection: Bones protect vital organs, such as the brain, lungs, and heart.
      • Movement: Muscles work with bones to facilitate movement.
      • Blood Cell Formation: Bone marrow produces red blood cells.

    Human Skeleton Overview

    • At birth, humans have 270 bones.
    • This number reduces to 206 bones during adulthood.
    • The hands and wrists contain 27 bones each, totaling 54 bones.
    • The feet and ankles contain 26 bones each, totaling 52 bones.
    • These two areas combined (106 bones) account for over half of all human bones.
    • Each wrist has 8 bones.
    • Each ankle has 7 bones.
    • The skull has 22 bones.
    • Some bones are unique, such as the hyoid bone.
    • Other bones are paired, such as the legs, arms, ribs, hips, etc.
    • Each bone has unique features, such as projections, depressions, ridges, and other characteristics.
    • These features help bones connect to each other and allow for muscle attachment.
    • Cardinal directions used to describe human bones:
      • Superior, inferior, medial, lateral, anterior, posterior, proximal, distal.

    The Cranial Skeleton

    • The cranial skeleton is crucial for forensic anthropologists in determining the time since death.
    • Determining the time since death is essential for:
      • Assessing the forensic significance of a case
      • Identifying the person responsible for a death
      • Identifying the individual
    • Post-mortem intervals: the noticeable changes that occur on an inanimate body over time.
    • Techniques used by medical examiners and forensic pathologists to estimate time since death in the first hours after death:
      • Liver Mortis: The pooling of blood towards the center of gravity, creating a purplish discoloration. It becomes visible 2 hours after death and is most noticeable between 8-12 hours.
      • Algor Mortis: The cooling of the body after death begins shortly after death and lasts 8-36 hours.
      • Rigor Mortis: The stiffening of the body, starting 2-6 hours after death and lasting 24-84 hours.

    Forensic Taphonomy

    • Forensic Taphonomy: The multidisciplinary study of the stages a human body goes through from freshness to complete skeletonization.
    • Stages of decomposition:
      • Autolysis: The body's own enzymes (like those in the stomach) begin to break down tissues.
      • Putrefaction: Microorganisms, primarily bacteria from the intestinal tract, multiply and begin to decompose the body. They break down biological components, leading to the production of gases and odors.

    Factors Affecting Decomposition Rate

    • Factors that can accelerate or slow the rate of putrefaction and decomposition:
      • Insect Activity: Insects actively decompose the body if accessible. The absence of access can delay the process.

    Estimating Stature

    • Stature (Height): Can be estimated from the lengths of long bones.
    • Full Skeleton Method (Most Accurate): This method utilizes all long bones and adds a correction factor for soft tissue loss.
    • Partial Full Skeleton Method: More recent studies have shown that only certain bones are necessary for accurate stature estimation.
      • The femur, tibia, and lumbar vertebrae are sufficient for this method.
      • Formulas for Stature:
        • Stature = 47.67 + 2.09 X (femur length + sum of lumbar vertebrae)
        • Stature = 48.63 + 2.32 X (tibia length + sum of lumbar vertebrae)
      • Soft tissue correction factors are not needed for these formulas.
    • Long Limb Bones Method ([Requires Skeletal Sex and Ancestral Group]) While less accurate than the full skeleton method, it is a common technique.
      • This method uses the lengths of long bones (arms and legs) to predict living height.
      • Mildred Trotter's Contributions:
        • Analyzed over 5000 bodies from WWII and the Korean War to establish correlations between bone lengths and stature.
        • Her research found that:
          • Arm and leg bones can estimate living height.
          • Right and left limbs are nearly identical and can be used for calculation.
          • Long arms often correlate with long legs and vice versa.
