A lethal weapons agent finds a firearm at a scene. What is the correct initial step before packaging it as evidence?
Answer: Clear the weapon and render it safe before packaging
Before packaging a firearm as evidence, it must be cleared and rendered safe to protect personnel handling the evidence.
When collecting biological evidence such as blood at a scene, an Act 235 agent should use which type of container?
Answer: Paper bags or breathable containers to prevent mold and bacterial growth
Biological evidence should be stored in breathable paper containers because airtight plastic traps moisture and accelerates decomposition.
During evidence collection, an Act 235 agent realizes a piece of evidence may have been moved before their arrival. What should they do?
Answer: Document the known or suspected disturbance in their report
Any known or suspected disturbance to a scene must be documented in the report so investigators and courts are aware of potential contamination.
Which of the following is a proper technique for collecting trace evidence such as hair or fibers?
Answer: Using clean forceps or tape lifts and packaging in paper folds or envelopes
Forceps or tape lifts prevent contamination from skin oils, and paper packaging prevents moisture buildup that can destroy trace evidence.
Under Act 235 standards, what must accompany each item of evidence when it is submitted to storage or a lab?
Answer: Properly completed evidence tags or labels with case number, date, and collector ID
Each evidence item must have a properly completed tag or label including case number, date, location, and the collector's identification to maintain chain of custody.
