Final answer:
The collection and packaging of tool-mark evidence involves preserving the tool in its original state, documenting the location and orientation of the mark, and packaging it in a rigid container.
Step-by-step explanation:
The correct answer is A) Preserve the tool in its original state, document the location and orientation of the mark, package in a rigid container. When collecting tool-mark evidence, it is important to preserve the tool in its original state, as any changes or alterations to the tool can affect the accuracy of the analysis. Documenting the location and orientation of the mark helps establish its context and can be useful in the investigation. The tool should be packaged in a rigid container to prevent any further damage or contamination. . Special considerations are taken for organic artifacts, which may require being frozen to prevent decomposition or treated with special chemicals, such as an ammonium glycol solution to stabilize decay. These methods help to ensure that the evidence can be analyzed in the best possible state.
It is not advisable to clean the tool thoroughly before packaging, as this could remove important trace evidence. Additionally, creating additional marks for comparison should only be done under controlled conditions and is not a part of the initial evidence collection process. Storing in a plastic bag is acceptable only if the risk of condensation and contamination is properly managed.
