Tools and tool marks are often found at burglary scenes and can be useful evidence. Proper evidence collection by the field investigator would include:
◦ Packing of tool and tool mark evidence together so that the crime lab personnel know they are thought to be a matched set.
◦ Reporting whether a tool found at the crime scene fit into the tool marks.
◦ Taking a photograph and cast of the marks if necessary.
◦ Making test marks with the suspected tool onto a soft metal surface at the crime scene.
