Evidence Examinations

Toolmark Examinations

Toolmarks

Tools can bear unique microscopic characteristics because of manufacturing processes and use. These characteristics can be transferred to surfaces that contact the tools. Evidence toolmarks can be compared to recovered tools. In the absence of a questioned tool, toolmark examinations can determine the type of tool(s) that produced the toolmark and whether the toolmark is of value for comparison.

Fractures

Fracture examinations can determine whether evidence was joined together and subsequently broken apart.


Submitting Toolmark Evidence

Questions concerning toolmark evidence should be directed to 03-9702366. Follow the Evidence Submission directions including Requesting Evidence Examinations and Packaging and Shipping Evidence.

  • If possible, submit the toolmarked evidence. The Laboratory will make a cast of the toolmark, if needed.
  • If it is not possible to submit the toolmarked evidence, submit a cast of the toolmark. For details about producing casts, see the Casting Three-Dimensional Impressions section of Shoeprint and Tire Tread Examinations.
  • Photographs locate toolmarks but are of no value for identification purposes.
  • Obtain samples of any material deposited on the tools.
  • To avoid contamination, do not place the tool against the toolmarked evidence.
  • Submit the tool rather than making test cuts or impressions.
  • Mark the ends of the evidence and specify which end was cut during evidence collection.
