Crime Scene Investigation Procedures Flashcards

What is the proper term for the written account a CFL submits documenting findings, methodology, and conclusions?

Answer: Forensic examination report

The forensic examination report is the formal document recording the CFL's methodology, findings, and conclusions in a legally defensible and professionally structured format.

Why must a CFL's forensic report use precise, objective language rather than subjective conclusions?

Answer: Objective language ensures findings are defensible in court and not characterized as speculation or bias

Precise, objective language ensures the CFL's conclusions are grounded in observable evidence, making the report defensible under cross-examination in legal proceedings.

When a CFL is retained by a defense attorney, what ethical obligation applies to findings that support the prosecution's theory?

Answer: The CFL must report all findings accurately regardless of which party they favor

A forensic expert's ethical obligation is to truth and accuracy regardless of who retained them — all relevant findings must be reported honestly and completely.

What is the role of comparison standards in a CFL's forensic report on tool marks?

Answer: Known tool mark exemplars provide a basis for comparing whether a suspect tool made the questioned marks

Known exemplars created with a suspect tool allow direct scientific comparison to questioned marks, supporting or refuting tool-to-mark associations in the forensic report.

A CFL's report concludes a lock 'could not have been opened without the correct key or a bypass tool.' What type of conclusion is this?

Answer: A qualified conclusion that honestly acknowledges the range of possibilities based on available evidence

Qualified conclusions that state what is possible or consistent with evidence — rather than claiming absolute certainty — reflect sound forensic practice and honest acknowledgment of evidentiary limits.

Which case management practice is most important for a CFL handling multiple concurrent investigations?

Answer: Strict case file separation with unique identifiers to prevent cross-contamination of evidence and documentation

Strict separation of case files and evidence with unique identifiers prevents cross-contamination and ensures each case's chain of custody and integrity are maintained independently.
