Sample item

Which statement about estimating time since death is most accurate?

ABody temperature is unaffected by the environmentBRigor mortis alone gives an exact timeCA single sign can establish an exact time in every caseDIt is an approximation based on multiple findings and environmental context

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. It is an approximation based on multiple findings and environmental context

Time-since-death estimation integrates cooling, lividity, rigor, decomposition, scene conditions, and other evidence. Each sign is variable, so conclusions should be expressed with appropriate uncertainty.

Option by option

A. Body temperature is unaffected by the environment
Ambient conditions substantially affect cooling.
B. Rigor mortis alone gives an exact time
Rigor varies with temperature, activity, illness, and other factors.
C. A single sign can establish an exact time in every case
No individual postmortem sign is universally exact.
D. It is an approximation based on multiple findings and environmental context (correct)
Correct. Forensic timing is multifactorial and approximate.
