Title: Forensic Art


1
Forensic Art
  • Pathology 4

2
Forensic Approximation
  • Forensic approximation is a process that attempts
    to recreate unidentified persons likeness
  • Uses several sciences to make accurate
    predictions
  • Anthropology
  • Osteology
  • Anatomy
  • There is also an element of art

3
Forensic Approximation
  • Used for non-criminal applications as well as law
  • Legally controversial
  • Fails the Daubert Standard (1993)
  • Expert testimony
  • No two experts would derive the exact same
    conclusion
  • Not admissable as evidence in court
  • Can be used as an investigative aid only

4
Forensic Approximation
Forensic approximation of the Spirit Cave Man,
one of only a few complete skeletons found in the
United States over 8,000 years old.
5
Forensic Approximation
  • History
  • First used in 1883 for archeological digs
  • First study of facial tissue thickness was
    completed
  • First used in forensics in 1962

6
Identification
  • Two types of identification
  • Circumstantial
  • Individual fits the general profile for a set of
    skeletal remains
  • Positive
  • Individual has unique set of characteristics
    shared with skeletal remains
  • Facial reconstructions are the most common

7
Facial Reconstructions
  • Generally based on skull, photographs, x-rays
  • Usually require both an anthropologist and an
    artist
  • 3 Types
  • 2D Reconstruction
  • Hand drawn or computer generated portraits
  • FACE and CARES software
  • 3D Reconstruction
  • Includes sculptures, 3D computer imagery

8
3D Facial Reconstruction
9
Facial Reconstructions
  • Superimposition
  • Only useful if there is some idea of the remains
    identity
  • Places a photograph over x-ray of skull and looks
    for similarities

10
Superimposition
11
Facial Reconstructions
  • Thorough exam of skull needed
  • Muscle attachments
  • Damage, wounds
  • Shape of skull, eyes, nasal openings
  • Skull cleaned and damaged areas repaired with wax
  • Mandible reattached
  • Eyes inserted
  • Pegs used to identify typical tissue thickness
  • Nose is largely an educated guess

12
Soft Tissue Reconstruction
13
Limitations of Facial Reconstructions
  • Insufficient data
  • Face is extremely complicated
  • 10 muscle groups in human face
  • Subtle differences between races, sex, body
    builds
  • Cartilage does not remain
  • No standardization
  • Different techniques and approaches
  • Subjectivity
  • Wrinkles, birthmarks, skin folds

14
Famous Reconstructions
In 2005, forensic anthropologists and artists
worked together to create the face of the
legendary King Tut.
