Sample itemWhat does a patterned abrasion on skin most often indicate?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Contact with an object that reproduced its surface pattern
Patterned abrasions may transfer the shape or texture of the impacting object, providing useful forensic information about the mechanism of contact.
Option by option
A. A spontaneous allergic eruption
Allergic rashes do not reproduce object patterns.
B. A deep penetrating firearm injury
Firearm wounds have different entry and exit features.
C. Contact with an object that reproduced its surface pattern (correct)
Correct: the surface pattern can be imprinted by contact.
D. An internal natural disease
Internal disease does not create external contact patterns.
