Paper packaging allows biological evidence to breathe, preventing the moisture buildup that promotes mold and bacterial degradation.
An investigator is reviewing recorded surveillance footage as evidence. What is the most critical first step?
Answer: Verify the timestamp accuracy of the recording device
Verifying timestamp accuracy ensures the footage accurately reflects when events occurred, which is foundational to its evidentiary value.
What is the purpose of using a scale or ruler in evidence photography?
Answer: To provide a reference for the actual size of evidence items
A scale placed next to evidence in photos allows viewers to accurately gauge the size of items depicted.
Which of the following is NOT a characteristic of a reliable written investigative report?
Answer: Inclusion of the investigator's personal opinions as facts
Reports must distinguish between objective facts and the investigator's opinions, and personal opinions should never be presented as established facts.
A witness recants their statement after initially cooperating. What should the investigator do with the original documented statement?

Both the original statement and the recantation are relevant evidence; altering or destroying documents could constitute obstruction.
What is the primary function of an evidence log or evidence receipt?
