Question

Which is not a method for collecting a toolmark on a doorframe
1) casting that portion of the doorframe
2) making a rubbing of the mark on the frame
3) photography
4) removing that portion of the frame

Answer 1

The answer to the question is Option 2. In other words, making a rubbing of the mark on the frame is not advisable to collect the tool mark on the door frame.

First, a cast of the portion of the door frame containing the tool mark is made. Then a photograph of the tool mark is taken to determine its exact position on the frame. Using this as a guide, remove that part of the frame which has the tool mark.

It is advisable not to do any rubbing on the tool mark as this can smudge the mark and make it difficult to find its exact location on the frame.
