The imprint of impacting instrument is clearly visible on affected tissue
What is Patterned Trauma
This type of sharp-force tool has a thin blade with a bevel that may terminate in a point. It may be straight or serrated and it may be single or double edged.
Rapid application of force over a relatively small surface area, usually bullets from a firearm
What is high velocity projectile trauma
The exposure of the body to high temperature or direct contact with flames
What is Thermal Exposure
identity based on context and/or personal effects
What is Presumptive identification:
The separation of the outer layer of bone
What is Delamination
This type of sharp-force trauma is characterized by a penetrating wound from pointed instruments directed vertically to a bone surface. It has circular to oblong pits with pointed floors
What is a Puncture Wound (stab wounds)
projectile impacts at extreme oblique; almost parallel; enters then knocks out edge of bone; looks half entrance, half exit; both internal and external beveling
What is Keyhole defect shape
What are the color changes associated with thermal exposure
the matching of a set of remains to a known individual
What is Personal identification
What can cause blunt force trauma?
What are Broad impacts to skeleton and/or Skeleton impacting broad surface
Dismemberments are typically done
what is postmortem
The diameter of bullet and/or barrel of handgun or rifle
What is Caliber:
What is shrinkage
The scientific matching of antemortem and postmortem records to sufficient detail to conclude that they are from one individual to the exclusion of all other reasonable matches
What is Positive (scientific) identification
How fractures initiate and propagate
What are..
This type of saw cuts along the grain
what is a rip saw
stellate pattern of fractures extending around impact site
What are Radiating Fractures
These are a result of soft tissue shrinkage and bone fragility
Heat induced fractures
Types of positive ID
What are
This fracture is characterized by the separation of entire face from braincase
What is LeFort 3
Sharp force trauma has four of these
what are types (Puncture, Incisions, Clefts, Saw Marks)
Given the same caliber several factors influence the size and shape
What are
“boxer-like” body posture of flexed elbows and knees and clenched fists, caused by the shrinkage of body tissues and muscle due to dehydration caused by heating
what is the pugilistic pose
This individual studied the reliability of the frontal sinuses in positive identification
