Forense examen final Flashcards
(53 cards)
Task of identification falls upon
Forensic scientists, forensic anthropologists, forensic odontologists and fingerprint examiner
2 facts valid methods of identificaction rest on
the identity of the indivudual
particular uniqueness
Identification
process of verifying that the individual concerned is the same as the one known
Identifaction methods require
antemortem and postmortem data
Personal identification categories
tentative
circumstancial
positive
Uncorrelated pieces of evidence
body location
biological profile
tattoos
scars
personal effects
skeletal anomalies
mitochondrial dna
Technique Most frequently used of personal identificaction
Visual examination of soft tissue
Challenges in identification
skeletal bodies
decomposed
dismembered
badly burned
Evidence on highly probable identificaction
prosthetics or evidence of previous
medical care, fractures, congenital or traumatic deformities, unusual allometric relations,
epigenetic traits, morphological peculiarities, and abnormalities
Explainable diferences
trauma
surgical interventions
growth
degenerative changes
Comperative radiology
involves the direct visual comparison of antemortem and postmortem radiographs and matchimg specific visual findings
Radiographic identification is used when
burned, mutilated, decomposed, fragmented, skeletonized, and otherwise
unrecognizable human remains.
Typical steps of comparison in radiology
- Get a medical or dental X-ray taken before the person died.
- Take a new X-ray of the unidentified remains, using the same angle and size as the first one.
- Compare the two X-rays by looking at them side by side or by placing one over the other to see if they match.
Important features we look for in radiographs
unusual bone growth, healed fractures, defor-
mities, degenerations, pathologies, abnormal calcifications, tumors, trauma, and prosthetic
devices
Nonimaged records
The comparison of antemortem records, such as notes, charts, or other recorded information, to features or characteristics of skeletal remains
Steps Identification by written records include
(1)identification of the pattern, injury, pathology, or anomaly
(2) obtaining antemortem medical or dental charts and/or notes on the suspected deceased
4) 3) comparing the record to features of the skeletal remains, looking for consistencies and inconsistencies.
Anomalies examples
accesory bones, bipartle bones, sternal, septal, and other apertures, bifid or supernumerary ribs, vertebral shifts, axial anomalies, autoinmune diseases
craniofacial superimposition
identification method applied when an investigation has suggested that a set of remains relates to a particular missing person for whom photographs, videos or other images are available
Dna and forensic anthropology
encodes inoformation about the individuals inherited characteristics and the nuclear code is unique to each individual.
Nuclear DNA
allows identification by reference to the alleles and nucleotide sequences of heritable traits and markers contained in any human nucleated cell
admisibility of evidence
Forensic anthropologist are expected to meet structured standards regarding the validity, reliability, and application of their methods
Daubert criteria mention
- Has the theory or technique been tested
- What is the known or potential rate of error
- do standards exist for the control of the techniques’ operation
- Has the theory or technique been subjected to peer review and publication
- has the theory or technique been generally accepted within the relevant scientific community
Triology of Supreme Court decisions
- The testimony is based upon sufficient facts or data
- The test is the product of reliable principles and methods
- The witness has applied the principles and methods reliably to the facts of the case
Facial aproximation
An artistic reproduction of the soft tissue features of an individual involves the estimation or artistic reproduction of possible facial features based on the underlying skeletal structures
