What needs to be clarified
The task is to compare the location and nature of the traces rather than choose a convenient explanation from one photograph.
Materials to prepare
- Overall and close-up photographs of the container and packaging
- Information about transport, unpacking and later changes
- The object and available comparison materials, as agreed
What to compare
- Separate damage to the packaging, body and locking element.
- Check whether the proposed contact directions and areas are consistent.
- Record features lost through repairs or subsequent use.
Possible outcome of the analysis
The investigation may clarify whether the traces are compatible with the proposed mechanisms and define questions for further comparison.
Limits of the conclusions
Similar trace locations alone do not prove a common source; identifying a particular object requires suitable comparison data.
