What should be used to collect paint specimens from suspect tools found at a crime scene?

The correct choice for collecting paint specimens from suspect tools found at a crime scene is the use of small paper bindles. This method is particularly effective for several reasons.

Firstly, paper bindles allow for the proper preservation of the paint samples, minimizing the risk of contamination or degradation that can occur if the samples are stored in moisture-retaining materials like plastic. Paper is breathable, which helps prevent the buildup of moisture that could compromise the integrity of the paint.

Additionally, using small paper bindles ensures that the specimens can be easily handled and transported without risking damage. They are compact and can be securely sealed, allowing for an organized collection process that maintains the chain of custody. This is crucial in forensic investigations where the integrity of the evidence is paramount.

In contrast, while plastic bags offer safe handling and protection, they can trap moisture, potentially altering the characteristics of the paint sample. Paper envelopes, although they might seem like a reasonable choice, do not provide the same level of containment or protection as bindles for smaller samples. Glass vials, while suitable for certain types of evidence, are not practical for paint specimens due to their fragility and potential for breakage during handling.
