If you want to be a good detective, you need to know how to collect tool mark evidence. Tool marks are any marks left by a tool on an object, such as a bullet casing, a lock, or a bone. Tool marks can help you identify the type of tool used, the direction of force applied, and the possible motive of the perpetrator. Here are some steps to follow when collecting tool mark evidence:
- First, take a picture of the evidence with a ruler in the picture. This will document the size and shape of the tool mark and its location in relation to other evidence. Make sure the picture is clear and focused, and use a scale that is appropriate for the size of the mark.
- Second, record observations that might explain how a tool was used. This will help to determine the type and direction of force applied by the tool and the possible motive or intention of the perpetrator. For example, if you see a tool mark on a door frame, you might observe that the tool was used to pry open the door from the outside.
- Third, if possible, collect the actual evidence that contains the tool mark. This will preserve the physical characteristics of the tool mark and allow for further analysis and comparison with suspect tools. Use proper packaging and labeling techniques to avoid contamination and damage to the evidence.
- Fourth, if you cannot collect the mark, make a cast of the impression. This will create a replica of the tool mark that can be examined later and compared with other casts or tools. Use a suitable casting material, such as dental stone or silicone rubber, and follow the manufacturer's instructions carefully.
By following these steps, you can collect tool mark evidence that can help you solve crimes and catch criminals.
I hope this helps you understand the process of collecting tool marks from a crime scene.
