Current and Future Technology of Forensic Anthropology
Technologies in Forensic Anthropology
-Chemicals:
- help forensic anthropologist do their job better and more effectively by helping gather and study evidence
illumination of body fluids- certain chemicals which define chemical components of evidence
- cleanse things (make them clean)
-Microscopic technologies
- help define the minutest (smallest) details
- example: dust, plant, other matter
- specific time (help identify)
- Dual beam Microscopy
- provide high resolution and analysis in three dimensions
-Voice Stress Analysis vs. Polygraph
- Voice Stress Analysis- microphone attached to computer or digital recorder
- Polygraph- interment that is used to measure heart rate, blood pressure, and respiration.
-Facial recognition and fingerprint identification
- fingerprint identification is more accurate than facial
- (facial) since photography government agencies and private organizations
- (facial) similar to line-up techniques (group physically similar)
- (facial) "portrait parle" or spoken portrait (portraits could be sorted by common morphological characteristic or people who were repeatedly arrested)
-S.E.M (computer automation and detector technology that allows for rapid elemental analyses of small particles)
- Speed, accuracy, and consistency keys for moving forensic caseloads from lab to courtroom
- includes analysis of glass, paint, fiber, GSR (Gun shot residue) newest generation-----> utilizing energy dispersive x-ray spectrometers
- incoperates computer automation that allows for rapid automated elemental analyses of small particles or inclusions
-Triage tool
- "pulling the plug" to maintain "gold standard" (integrity of a hard drive) drive encryption
- vary in technical and operational performance capabilites
- quick access to a computers relevance to an investigation prior to removing its power and seizure
-Drawing
- important still get image of person/persons to put out an APB.
- Dark room: for getting photographs
-Toxicology
- more sensitive way to measure the amount of cyanide and carbon monoxide in blood
- (common traditional methods for measuring carbon monoxide rely on the use of spectroscopic techniques) -----> entail diluting a blood sample and shinning a light through it in a series of wavelenghts
- if body begins to decompose, the resultant bacteria, or putrefaction, can interfere with wavelenght
